Marijuana toxic to pets




There are few cities in the United States that have as much access to medical marijuana as Boulder does. With the increased availability of medical marijuana in our area, our pets are encountering more exposure to marijuana and its active chemical ingredient, tetrahydrocannabinol (THC). Unfortunately, THC is toxic to our pets, and exposure to marijuana can result in a very sick animal.

How exposure occurs


The vast majority of pet exposure occurs in dogs (95 percent). Our canine companions are notorious for eating, well, just about everything. Ingestion of marijuana is the most common way pets are exposed to the toxic THC. Marijuana edibles including butter, cookies and brownies are very tempting to pets. We all can imagine the Labrador Retriever sneaking onto the counter to eat those chocolate pot brownies. Some animals will ingest the raw plant leaves, seeds and even joints without hesitation. Finally, pets can also be exposed to second-hand marijuana smoke.


What marijuana does


THC is rapidly absorbed into the bloodstream. Signs of marijuana toxicity typically become apparent within minutes to a few hours. The most common symptoms of toxicity are neurologic abnormalities, including stumbling that potentially progresses to an inability to walk, depression, agitation, dribbling urine, twitching, seizures, pupil dilation and occasionally coma. Death is rare but can occur. About 30 percent of animals exposed to THC will develop gastrointestinal signs including drooling, vomiting and diarrhea. Because THC is lipid (fat) soluble, pets may exhibit mild to moderate symptoms for days as the chemical is slowly released from fat stores.

What to do


Seek medical attention immediately from your veterinarian. Depending on the timing of ingestion, your veterinarian will try to "decontaminate." He or she will likely give a medication to induce vomiting and administer activated charcoal to help limit further absorption of THC. Then, your pet may need hospitalization and supportive care including an intravenous catheter, IV fluids, heat support, heart rate and blood pressure monitoring. If symptoms are very severe, your pet may need more aggressive care to manage seizures and possibly breathing support. The good news is that with mild to moderate exposure and prompt medical care, most pets will recover from this toxic exposure.
Most importantly, be honest and up front with your veterinarian that your pet was exposed to marijuana. Our interest and goal is to help your pet achieve a healthy condition as quickly as possible. If we know right away what toxin we are battling, we will be able to provide appropriate and efficient medical treatment. Veterinarians are not obligated to report marijuana exposure, so there is no need for legal concerns regarding your use of marijuana.

Keeping pets safe


Foremost, please keep your medical marijuana, weed, bud, ganja, pot, brownies and joints safely contained and out of your pets' reach (i.e. closed cupboards, drawers, high closet shelves, etc.). Do not leave remnants in an open trash container nor in a compost bin that your pet may sneak into for a snack. When smoking, ideally keep your pet in a separate room away from the smoke. If this is not possible, smoke in a well-ventilated area to minimize your pets' exposure to second-hand smoke.

THC test


Yes. THC can be detected via blood or/and urine tests.


Do pets get high?

No. Marijuana exposure in pets causes neurologic toxicity, which is not the same as the "high" that people experience. The symptoms (staggering, agitation, stupor, etc.) that develop in pets do not appear enjoyable for them.


Med pot for pets?

Currently, marijuana is considered a toxin to pets, and there are no recommended uses. Marijuana is a complex substance, and the effects of THC on individual animals are extremely variable. Some animals become highly agitated from marijuana, while others exhibit signs of depression. There have been studies that show THC may have anti-seizure effects, while other studies indicate THC may provoke seizures. Some feel marijuana may reduce nausea, but roughly 1/3 of animals exposed to marijuana will develop signs of nausea and vomiting.
Furthermore, dosing in animals is challenging. The THC content varies in marijuana plants, complicating the ability to control a drug dose. Thus, at this time, there are no generally accepted medical or prescription uses for marijuana in pets.

Pet Toxins




As the weather clears, we usually see more pets with toxicity from mushrooms; however, there are many other toxins which your pet may ingest, like rat bait and snail bait. The new ones are even more toxic and difficult to treat than older ones. If you think your pet has ingested some, try to bring in the container that it came in so we know what the toxin is.



We see pyrethrin toxicity from some of the over the counter flea medications, especially in cats. Always come in ASAP if you suspect poisoning so we have a chance to induce vomiting.


Did you know that garlic, onions (including shallots and leeks) and even raisins and grapes can be toxic to dogs and cats?


Most people know about chocolate toxicity, but we see similar poisoning from coffee and other caffeine stimulants.


Human medicines are often dropped on the floor and scooped up by your pet. Pain pills, sedatives and vitamins can be toxic, as well as alcohol, marijuana and other drugs. Even lilies can be toxic to dogs and cats.

Here is a list of more pet toxins:

·         Easter Lily (All Lillies)
·         Mistletoe
·         Ethylene Clycol (Anti-freeze)
·         Snail Bait (Metaldehyde)
·         Macadamia Nuts
·         Rat or Gopher Poison
·         Some Flea Products with cats
·         Human & Pet Prescriptions
·         Illegal Recreational Drugs
·         Human & Pet Non-steroidal Anti-inflammatory Drugs
·         Antidepressants
·         Moldy Walnuts
·         Grapes or Raisins
·         Chocolate
·         Cocoa Mulch
·         Wild Mushrooms
·         Insecticides
·         Compost
·         Garbage

Technology Brings Stem-Cell Therapy In-House

Stem-cell therapy for the treatment of joint diseases in animals, particularly dogs, cats and horses, has been available in the U.S. for a number of years. Today, second-generation technology is enabling more veterinarians to take advantage of this modality by making the investment less expensive and improving the process and delivery.

Proponents say stem cells harvested from adipose tissue accelerate the healing of muscles and joints in adult animals suffering from osteoarthritis, hip dysplasia, ligament and cartilage injuries and other degenerative joint diseases.

Researchers have found that “activating” stem cells before returning them to the animal’s body enhances the healing of these musculoskeletal problems.

“This technology can be adapted for any animal, be it a dog, horse, cat or an exotic,” said Mike Hutchinson, DVM, owner of Animal General of Cranberry, near Pittsburgh. “We take that individual’s fat, process it and activate the stem cells. Then, we put them back into the same animal. We are using the animal’s own repair system, the adult stem cells.”


Because it is an autologous procedure, he said, it is safe and effective.

MediVet America of Nicholasville, Ky., is the company that sells the in-clinic equipment, adipose stem cell procedure kit and provides banking services for harvested cells.

Hutchinson said MediVet’s recent improvements in processing have increased the number of stem cells collected, shortened the time from harvest to delivery because everything is performed in-house, and made the technology less expensive to the veterinarian.



How It’s Done



Under anesthesia, adipose tissue is harvested from the thorax or abdomen.


Stem cell therapy in animals starts with the harvesting of adipose tissue from the thorax or abdominal area while the animal is under general anesthesia.

“The animal will be anesthetized for about 10 to 15 minutes,” said Hutchinson, a national spokesman for MediVet who has performed the procedure about 300 times. Then, the pet is awakened and kept in recovery while the veterinary technician extracts the stem cells. Once the cells are processed, the animal is sedated and the stem cells are injected into the affected joint(s) and given intravenously.

Veterinarians need harvest only about 20 grams of fat—a little more than a tablespoon—to collect 400 to 600 million stromal cells, and the extra cells can be banked for future treatments, said Darren Marks, DVM, a partner at McGilvray Veterinary Hospital in Toronto, and a spokesman for MediVet Canada.

Instead of sending the harvested tissue to a laboratory to separate the stem cells from the adipose tissue, this process now can be performed in the veterinary clinic.

The harvested adipose tissue is broken down by an enzyme wash, then centrifuged to obtain stem cells.


During the process, a blood sample is also taken and is centrifuged to separate contents and create platelet rich plasma (PRP). Rich in many growth factors, PRP is used in veterinary medicine, particularly in equine medicine, to aid tissue healing. The veterinary technician adds the PRP to the stem cells and puts the mixture under an LED light, which activates the cells outside the body.

“We are using PRP and photostimulation, which activate the stem cells and cause them to proliferate in much higher numbers, and that is a big advantage,” Hutchinson said. “It also helps enhance the amounts of anti-inflammatory growth factors that are helping the body reduce pain and inflammation.”

Once the fat is harvested, processing the stem cells takes about 21/2 hours, with the veterinary technician doing about 80 percent of the work, Marks added.

Most owners report improvements in range of motion and mobility in three to 10 days. The stem cells will continue healing for weeks to months, and the effects last at least a year or more on average, Hutchinson said. Depending on the extent of the joint injury and the age of the animal when it first receives regenerative medicine, some animals will need periodic treatments.


Hutchinson said it is important to frame owners’ expectations so they understand that the animal is suffering a degenerative disease, and that stem cells cannot “cure” arthritis. Instead, he said, stem cells will aid in healing, reverse some of the degenerative process and provide substantial pain relief, but over time, the joint will begin to degenerate again.

It bothers him when people talk about getting their “puppies and kittens” back.


“We are not turning a 10-year-old dog back into a puppy, but we are providing tremendous pain relief, so they feel better and they move around better,” he said.




The tissue is collected for processing on site.

Getting Ready

Because the patient undergoes general anesthesia, veterinarians are advised to perform an examination and pre-surgery blood chemistry. In addition, stem cell therapy is contraindicated in animals with malignancies, so experts recommend a radiograph of the chest and abdomen to make sure there are no tumors. Hutchinson said if the results show any abnormalities that would signal the animal might have problems with anesthesia, he might do more tests. For instance, an animal with a slightly enlarged heart or a murmur might be given an EKG. He likened the pre-surgery work-up to what an older dog receives before a dental.


Small Learning Curve

Veterinarians looking at this new technology tend to ask two questions:

  • Can I do it?
  • What are the side effects?
Marks said the collection and processing of stem cells is already in the skill set of every veterinarian and every veterinary technician.

“We all do surgery,” he noted. “We make an incision and remove the fat pad. I take it from the behind the shoulder; some people take it from the abdomen. Then, we hand the fat to the technician, who processes it. Technicians do lab work all the time.”

The administration of stem cells is also simple.

“Intra-articular joint injections can be tricky, but we’ve all been trained to do them, so most veterinarians just need to be reminded how to do them,” Marks said. When tissue is injured, damaged cells release chemicals to attract anti-inflammatory cells, so the stem cells will home in on injured tissue, even if the veterinarian misses the exact spot where the stem cells are needed when injecting the joint.

MediVet recommends administering an intravenous dose of stem cells, which circulate around the body seeking inflammation. They appear to help other inflammatory conditions, Hutchinson said.

“Owners come in and ask, ‘By the way, Dr. Mike, does this help the skin? Because my dog has allergies, but isn’t scratching as much,’” Hutchinson said. “As a result, researchers are testing the effect of regenerative medicine on immune system diseases like atopy and inflammatory bowel disease.”

Veterinarians should watch for injection-site reactions and infection, although Hutchinson and Marks said that if the veterinarian follows basic infection control procedures, infection should not be a problem.

“There is always a possibility that you can introduce infection when you inject a joint, so sterile technique must be used,” Hutchinson said. “But I’ve injected more than 900 joints, and I haven’t had one infection. We don’t expect a lot of adverse events with stem cells.”




Once processed, the animal’s stem cells are injected intra-articularly.

"Why are vets so expensive?" by Dr. Marie Haynes



Sometimes I hate my job. Well, that’s not true. I almost always love my job. But what I hate is that everything I do costs people money. Multiple times per day, I am helping people make decisions for their pets based on how much they can afford.

“All vets think about is money!”

“You don’t care about my pet, all you care about is getting rich!”

“Why does it cost so much to clean my pet’s teeth? My own dentist is cheaper!”

Unfortunately these are remarks that I hear on a regular basis. And I feel for you guys! It can be expensive to keep a pet healthy these days. I thought I would write this article to explain some of the facts about the financial side of veterinary medicine.

 

A veterinary hospital is a business:


Doesn’t that sound heartless? But it’s true...a vet clinic is a business and needs to make money. Just like any other business we have bills to pay (and often these bills are huge). We pay rent, electricity and gas bills. And we pay large bills to buy and maintain equipment. An xray machine costs anywhere from $30,000 to $90,000. An ultrasound is going to cost about the same. And there is a lot of other equipment that needs to be purchased and maintained - dental equipment (most veterinarians have similar equipment to what a human dentist has), equipment to run laboratory tests, surgical instruments, and on and on.

We also have salaries to pay. The staff at veterinary clinics are, in my opinion, usually severely underpaid for the quality of work that they do. A veterinary technician is an extremely skilled individual, able to place a catheter, draw blood, do a dental cleaning, counsel clients and multi-task animal care all day long. According to Payscale.com a Technician generally gets paid between $10 and $12 per hour.

It’s a crummy wage for someone with so many skills. Most technicians have gone to school for three years and carry some student debt. Compare this to a registered (human) nurse who gets paid between $20 to $36 dollars per hour. Why are techs paid so poorly? It's because we’d have to raise our prices in order to afford to pay them more.

 

What about the veterinarian’s salary?


I have a confession to make. I drive a BMW. There you go. Is this why vet bills are so expensive? To pad the pockets of greedy veterinarians? Well, here’s the rest of the story. My husband is a successful real estate agent. His recent business successes and hard work have paid for my car. Prior to this, for the last 10 years I have driven a 2002 Honda Civic. Now, there’s nothing wrong with a Civic...it’s a great car. But my point is that a veterinarian’s salary is not one that allows you to live in luxury.

Veterinarians on average have spent 7 years of their lives in college/university doing intensive study. According to the Journal of the American Veterinary Medical Association, the average veterinarian graduates with a debt of a whopping $142,613! And, according to Payscale.com, a veterinarian generally makes between $45,000 and $106,000 depending on experience. Let’s compare this to a few other professions:

  • Family Physician: $75,000 - $204,000
  • Pharmacist: $50,000 - $130,000
  • Dentist: $61,000 - $201,000
  • Ophthalmologist: $93,000-$304,000
  • General Surgeon: $65,000 - $368,000

A veterinarian does all of the things that the professions above do, but usually gets paid much less. Many vets work 10-12 hour days, and some are on call throughout the night. We get scratched and bitten on a regular basis. A good amount of our day involves intensive grief counselling of clients. This is not a “cushy” job. It’s hard work!

 

Explaining the charges for a vet bill


I thought I’d explain the way that some things are charged for. I'll occasionally hear people talking about their vet, saying things like, “I was in there for 20 minutes and paid $200! I’m in the wrong profession!”

Here is an example scenario:

John brings his Golden Retriever, Andy to see me, Dr. Marie, because he has a problem with his ears. I have a good look at Andy from nose to tail and notice that the ears are red, inflamed and full of debris. The skin between the toes is a little red as well and there is saliva staining which shows me that he has been licking at his feet. (This is likely a sign of allergies). Otherwise, he looks good. I put a swab in each ear and hand them off to my technician. We have a good discussion about underlying allergies and what kind of things we can do in the future if things are getting worse. (I decide not to do allergy testing or special hypoallergenic food now because I don’t want John’s bill to be outrageous. We’ll consider those things in the future.) We talk about the type of things that cause infection and what we could do to prevent further ones. Ten minutes later, my technician tells me that the ears have yeast and cocci (bacteria). She takes Andy to the back to thoroughly clean his ears. We send him home with some medication to put in the ears twice a day and instructions to come back and see me in a few weeks.

Here are the costs for the visit, along with an explanation:

Office visit: $68.00.


What you’re paying for: The most important part of the office visit is the time and expertise of the veterinarian. In that 20 minute time period, the vet will examine the pet, make a diagnosis and share valuable information with you. I have had clients say things like, “I knew there was an ear infection! I didn’t need you to tell me that. I just needed medication.” But, it’s the vet’s experience that tells us how long we need to treat for, what medication is best, whether or not there are ear mites, whether we need to treat one ear or both, whether there is possibly a resistant type of bacteria present, whether the ear drum intact (because if not, then regular ear medications could be dangerous) and whether there is an underlying problem such as allergies or a thyroid condition.

This charge also covers the time that I take to make notes in your file. Did you know that almost everything that is discussed and done in your office visit is documented? This is often one of the most time consuming parts of the visit for the veterinarian.


Cytology: $31.00.

What you’re paying for: This is a lab test where we take the debris from the ear, put it on a slide, stain it and look at it under the microscope. Some clients will say, “Just give me the medicine that worked last time. I don’t need a test.” But this test tells me a lot. It usually tells me which medicine is best. It also tells me the severity. If I see a mild amount of bacteria I may just treat for 10 days. If I see lots, I could treat for 3 weeks. If I see rod bacteria, then I'm suspicious I'm dealing with a nasty pseudomonas infection and I know that I should be doing additional tests such as culturing the ear to find out exactly what the bacteria is and what medication is going to work.

At the recheck exam I do a cytology again and it tells me how well our treatment worked and whether we need to keep going. If we stop too soon then the infection will come back again. Spending a little money now and dealing with the problem properly can save you hundreds of dollars in the long run.

Ear cleaning: $28.00.

What you’re paying for: The expertise of the technician. Cleaning an infected, inflamed ear takes skill and expertise. If the ear is not properly cleaned, then the medicine is not going to work as well. If you don’t know what you are doing, then you can damage the ear drum which is a horrible thing.


Medication: $38.00.


What you’re paying for: The bulk of this charge is due to the cost of the medication. There is a markup on the cost, because (gasp) we are a business and yes, we do make some money off of medication. There is also a dispensing fee. This is another thing that people will gripe at. “Why charge me to put pills or cream in a bottle and slap a label on it?”. The dispensing fee also covers the explanation on how to use the drug and answering questions that you have about it.


Taxes: In my area the taxes on this bill would be $21.45.


Total: $186.45

What happens when clients can’t pay?


This is the part of my job I hate the most. I think every new veterinary graduate goes through a phase where you want to just pay for the bill for anyone who can't afford it so that no animal has to go without help. It truly sucks when an animal needs care but the owner is not able (or not willing) to pay for that care.

So, whose responsibility is it to make sure that that animal gets help? Let’s take the above scenario. Let’s say the client comes in with a $50 bill in his pocket and says, “Doc, I love my dog so much and I’ll do anything for him but all I have is $50. I know you love animals and don’t want him to suffer so please help.” What am I to do?

One one hand, I could look at the situation like this:

“Well, what does this actually cost me? The office visit and tests really only cost me time. So, if I just charged for the medication, this dog could have some relief.” But, how is that fair to the next person who comes in with a dog with an ear infection? What if I give an inappropriate medication (because I didn't do tests on the ear)? If the dog doesn't improve, is it then my fault? And what happens the next time this dog has a problem? Do I always give this owner a huge discount? What happens when he tells his friends that I gave him a huge discount? I’m sure there will be others who want the same treatment!

Here’s another, much more difficult scenario:

 

Need life saving surgery - but can't afford it!


Susan comes in with her beloved chihuahua, Peppy. Susan could not afford to spay Peppy and although she tried hard to keep her away from other dogs, a big dog jumped the fence in her yard and bred Peppy. Now, she is pregnant, in labor, and struggling. Susan comes in crying. She and I both know that Peppy’s going to need a C-Section in order to survive. She has $100 to pay me today. And she promises to pay me $100 per month until the bill is paid off.

A C-Section can cost anywhere from $800 to $2500 or even more if there are complications. Often, extra staff needs to be brought in and the costs to the clinic are significant. What do I do? What would you do if you were the vet?

Unfortunately, history tells me that if I set up a payment plan, I will not receive any of that money. Susan has good intentions, but good intentions don't pay bills. In 13 years of practice I have unfortunately been in this situation many, many times. In the past, when I have made arrangements for clients like this, it has been extremely rare that we have received the full payment for the bill. In most cases, we may get one or two payments. We end up spending money on collection agencies to try and get the rest of that payment back but usually it gets written off as bad debt.

So, whose responsibility is it to help the animals in a situation like this? Do I do the surgery, knowing that I will likely not get paid, simply because the dog needs it? (Keep in mind that a situation like this can happen several times per week in a veterinary hospital. Where do we draw the line?) Do I send the dog away and tell her to come back when she has the money?

Can you see why I hate this part of my job?

 

What can be done?


There are options for people who are in a difficult situation like this. These options are not always what the client wants to hear, but we have to set some limits. The first thing I do is give the client the option of using Medicard or Care Credit. These are financing agencies that will give you a loan to help you pay a veterinary bill. I hear the cries now, “I don't want to pay interest!”, “I have bad credit...I won’t get approved.”

If a client's credit rating is not good enough to be approved for one of these loans, then I ask the client to find a family member or friend who would be willing to lend them the money. Sometimes this is a solution.

But what happens when you have bad credit and no family or friends at all to help? If this is the case, then why should the veterinarian pay for your pet’s treatment? If your children are hungry and you can’t afford groceries, is it the responsibility of the grocery store to pay for their food?

 

Organizations:


Sometimes, we can draw on charity help in situations like this. In Ontario, where I practice, we have something called the Farley Foundation. This organization will give us up to $500 per year to help pay the veterinary bill of someone who has a documented disability. $500 is not a lot, but it can help. I get to use this once a year. It's often tough to choose which client gets the help.

Before my mom succumbed to cancer in 2001, she went to the veterinary hospital where I had worked in high school and asked if she could set up a fund to help people who had trouble paying their vet bills. (She did this because when I was growing up we struggled to pay our veterinary bills. She didn't want others to be in that situation.) When she died, instead of asking people to donate to the cancer society, she asked for donations to the fund in her name at the animal hospital. This helped many animals, and, to this day, people still contribute to this fund in order to help more pets. But, again, this can only go so far.

I have compiled a list of similar charities that help as much as they can. You can find this list here: organizations that help with veterinary bills. If you know of other organizations that do this, then leave me a comment below and I will add them to the list.

 

Humane Societies and the SPCA


If an animal is suffering and needs care, in many areas an option is to take them to the local humane society or SPCA. In the case of the dog needing a C-Section this is likely what I would have suggested. Many times the humane society or SPCA will take in the pet and do whatever medical care is necessary. The unfortunate thing is that in many cases you will need to sign the pet over to the care of the shelter and you may not get them back.

 

Conclusion:


Oh, how I wish that I could do my job and not care about how much things cost! For those of you reading this, I would highly advise that you look into getting pet insurance to cover you in case you find yourself in a financial bind. Or, if you are an organized person, put some money aside each month in an account that for your pet.

I sympathize with you on how expensive veterinary bills are. It would be so wonderful, as a vet, to be able to practice and make decisions for animals based on what they need rather than what their owners can afford (or are willing to pay). I do all I can to work with my clients’ budgets and to do the best for their pets. But, sometimes we do face difficult situations!
