This information was found at https://wagwalking.com/condition/marijuana-poisoning

With the legalisation of Cannabis Veterinary Clinics have seen an increase in Cannabis Intoxication in pets. As pet owners we have to be more vigilant when we are out walking our dogs. Cannabis users have the responsibility to make sure they discard the joint bud safely and if they use cannabis at home to keep it out of reach.

Symptoms of Cannabis poisoning include:



 Hypermetria (spastic, high stepping “over-measurement” gait in all four limbs, most evident in the thoracic limbs).


Mydriasis (dilated pupils)

Body tremors

 Bradycardia (low heartrate)



Ataxia (unsteady on their feet)

Tachycardia (increased heartrate)

Tachypnea (breathing faster than normal)

Nystagmus (unintentional eye movement)



Dogs can become poisoned by marijuana in various forms. Different ways of marijuana ingestion that can greatly affect dogs include:

Inhalation of smoke

 Ingesting pills or tinctures

Eating edible items that contain the plant, such as brownies, candies, cakes, breads, and other baked goods

 Drinking liquids that contain marijuana oils, known as “shatter”, BHO, or “dabs”

 Treatment of Marijuana Poisoning in Dogs:

 Marijuana poisoning can be serious if your dog consumed a large quantity of the plant. Due to the varying toxicities that dogs have, treatment methods will vary. Techniques the veterinarian will use to treat your dog may consist of the following:

IV Fluids: IV fluids may be necessary if your dog has been vomiting in order to prevent dehydration.

Sedation may be given if your dog is overly excited. Diazepam and chlorpromazine may be given to assist in any negative central nervous system effects.

Medications:  Your dog may be given a medication to prevent him from vomiting. Due to the toxic properties of marijuana and the sedative effects your dog may be having, any vomiting your dog does must be controlled and monitored. Repeated vomiting also can cause dehydration. Your veterinarian may decide to induce vomiting if your dog has a high level of toxicity and will follow this up with activated charcoal. 

 Monitoring: Your dog’s oxygen levels and blood pressure will need to be monitored the whole time he is with the veterinarian and being treated. In severe cases of marijuana poisoning, many dogs are put on a ventilator or respirator. Thermoregulation is also conducted in severe cases.

Recovery of Marijuana Poisoning in Dogs:  Marijuana toxicity can be very serious if treatment is not administered as soon as possible. Once your dog recovers, your veterinarian will discharge him. When home, you will need to closely monitor his recovery and follow any instructions your veterinarian has given you.  Your veterinarian will give you detailed directions on how to care for your dog and will tell you what you need to watch for in terms of any new symptoms. Depending on your dog, if his gastrointestinal tract was severely irritated from vomiting or diarrhea, your veterinarian may suggest a special bland diet while he is recovering. It is important to keep any follow-up appointments with your medical professional so you can be assured your dog is becoming well once again. To prevent marijuana toxicity, it is important to keep all marijuana and all types of substances that contain marijuana out of the reach of your loved one.
