If your pet has eaten cannabis or a cannabis-containing product, or is showing unusual sleepiness, poor balance, agitation, tremors, vomiting, urinary leakage or other concerning signs, contact your veterinarian or nearest emergency veterinary hospital promptly.Be honest about the product and possible amount involved. Accurate information helps the veterinary team provide appropriate care.Do not induce vomiting or give home remedies unless a veterinary professional specifically directs you to do so.

Veterinarians cannot authorize an animal to access cannabis through the medical-cannabis system in Part 14 of the Cannabis Regulations. That system applies to human patients and recognizes physicians and nurse practitioners as health care practitioners.Cannabis products sold by provincially or territorially authorized cannabis retailers are not approved veterinary drugs. Veterinarians cannot prescribe those retail cannabis products as drugs, although veterinary regulators permit informed discussions about legally obtained products and patient safety.Veterinarians may prescribe an authorized human or veterinary drug containing cannabis in accordance with the usual federal and provincial rules governing veterinary prescribing and extra-label drug use. At the time of this review, Health Canada reports that no veterinary drugs containing cannabis, including CBD, are authorized in Canada. An authorized human prescription drug containing THC and CBD is available, but its formulation and cannabinoid ratio are often unsuitable for veterinary patients. Health Canada’s current veterinary-cannabis framework

CBD is a phytocannabinoid and is regulated under the Cannabis Act regardless of whether it came from hemp or another type of cannabis plant. A product containing CBD is not automatically exempt from cannabis rules because it is labelled “hemp.”Health Canada permits notified hemp-based Veterinary Health Products. These products may contain eligible hemp ingredients, including permitted plant parts or hemp-seed derivatives containing no more than 10 parts per million THC. They cannot contain isolated or concentrated phytocannabinoids such as CBD.Notified Veterinary Health Products carry a Notification Number and may make limited general health claims, but not claims to treat, prevent or cure disease.Products marketed for pets as CBD products outside the authorized cannabis or drug pathways may not comply with Canadian law and may not have the quality controls or label accuracy expected of legal products. Health Canada’s information on CBD and industrial hemp

No. Hemp-seed oil is made from hemp seeds and is used as a food or nutritional ingredient. It should not contain meaningful concentrations of CBD or THC.A cannabis oil containing CBD is a regulated cannabis product, regardless of whether its CBD originated from the hemp plant.

Veterinary research includes studies involving osteoarthritis-associated pain, epilepsy, behaviour and stress, dermatologic disease, pharmacokinetics, safety and other areas.The amount and quality of evidence differ by species, condition, cannabinoid, formulation and outcome. The existence of a published study does not mean that:every cannabinoid product is effective;results can be transferred between different products;the same results should be expected in another species; orcannabinoids are appropriate for every patient.CAVCM provides access to published material through its Research Library. Treatment decisions should be made with a veterinarian and should consider established therapies as well as the evidence, risks and limitations of the product being discussed.

The endocannabinoid system helps regulate many functions in the mammalian body and interacts with the nervous, immune, gastrointestinal and other systems.Cannabinoids may also act through receptors and pathways outside the traditional endocannabinoid system. These widespread biological effects help explain why cannabinoids are being studied in many areas, but they do not establish that cannabis is effective for every condition.

THC can cause intoxication in animals, and dogs appear particularly sensitive to its neurologic effects.Risk depends on the dose, concentration, route, formulation, individual patient and whether the product contains other toxic ingredients. Even when most patients recover with appropriate care, intoxication can be serious and may require hospitalization.Edible products can present additional risks because they may contain chocolate, xylitol, raisins, caffeine, alcohol or high concentrations of THC. Smoke and vapour should not be used around animals.

Possible signs include:poor balance or difficulty walking;marked sleepiness;disorientation;agitation;dilated pupils;urinary leakage;increased sensitivity to sound or touch;vomiting;tremors or seizures; andchanges in heart rate, blood pressure or body temperature.A severely affected animal may become minimally responsive or comatose.Urinary leakage may occur but is not present in every case. Its absence does not rule out cannabis exposure.

Treatment depends on the product, amount, time since exposure and the animal’s clinical signs.A veterinarian may recommend observation, decontamination when it can be performed safely, supportive care, monitoring or hospitalization. Because a sleepy or neurologically impaired animal can aspirate, vomiting should never be induced at home unless a veterinary professional has assessed the situation and specifically instructed you to do so.The old detailed intravenous lipid-emulsion protocol should be removed. Treatment doses belong in current clinical references and must be tailored to the individual patient.

Start by speaking with your veterinarian. Share the exact product label, cannabinoid concentrations, ingredient list and any available certificate of analysis. Tell the veterinary team about all medications and supplements your pet receives and what outcome you hope to improve.Important safety principles include:Use only a legal product with clearly stated CBD and THC concentrations.Avoid products with unknown concentrations, unsupported health claims or incomplete ingredient information.Avoid human edibles and products containing ingredients that may be unsafe for animals.Avoid smoke, vapour, homemade extracts and highly concentrated products.Store all products securely and separately from pet food and treats.Record the product, lot number, concentration, amount given, timing, desired outcome and any changes observed.

There is no single dose appropriate for every animal or every cannabinoid product. Published studies have used different formulations, cannabinoid profiles and doses for specific species and conditions. Results from one product cannot automatically be applied to another product with a different concentration or composition.CAVCM does not recommend a universal public dosing chart.A veterinarian considering a cannabinoid product should evaluate the evidence for the intended use, calculate the actual milligrams of each cannabinoid, consider other medications and medical conditions, and arrange appropriate follow-up.Products containing THC require particular caution because individual sensitivity varies and adverse effects can occur at relatively low exposures.

Yes. Cannabinoids may add to sedation caused by other medications and may affect drug-metabolizing enzymes. The clinical importance varies with the cannabinoid, dose, product and concurrent medication.Extra caution may be needed for patients:receiving anticonvulsants or sedatives;receiving medications with narrow safety margins;with significant liver, kidney, cardiovascular or neurologic disease; orthat are immature, pregnant, lactating or used for breeding.Never stop or reduce a prescribed medication in order to start a cannabinoid product without speaking with the prescribing veterinarian.

Monitoring should be individualized. It may include:a physical examination;baseline or follow-up laboratory testing;medication-level monitoring;a structured assessment of the target problem;a record of the product and amount administered; anddocumentation of adverse effects.The appropriate plan depends on the patient, product, dose, treatment duration and concurrent medications.

Use current, authoritative sources and discuss animal-specific questions with a veterinarian.CAVCM’s pet-family resources explain product labels, veterinary conversations and response tracking.
