One of the downsides to the legalization of marijuana has been the increase in it’s availability to dogs. THC is extremely toxic and many dogs end up with a medical crisis due to carelessness around cannabis products. I know two dogs in the last year who hoovered up a butt end of a joint, found on the sidewalk, and ended up at the veterinary emergency.
We also need to be aware that the use of CBD with dogs is increasingly popular, but you need to discuss this with your vet and ONLY use products approved for the use with dogs. The research on the efficacy of CBD products with dogs is in it’s infancy so there is currently not a lot of research one way or the other about it’s use with our companion animals.

“The main toxic component of marijuana for dogs is the psychoactive chemical called tetrahydrocannabinol (or THC). Dogs can experience a toxicity by ingesting the plant directly, inhaling marijuana smoke, or eating baked goods or other foods laced with marijuana. Symptoms can start to appear 30 minutes to 3 hours after ingestion depending on the amount consumed, and the effects can last up to several days.
Symptoms of marijuana ingestion include:
In-coordination or walking wobbly/drunk
Low heart rate
Low blood pressure
Diagnosis and Treatment
If you know your dog may have ingested any marijuana, it is very important that you be honest with your veterinarian.
You aren’t going to get in any trouble and they aren’t going to call the cops on you! It is critical for the doctor to get all of the information to be able to properly treat your pet.
Diagnosis can often be made with the history and clinical symptoms alone. There is also a urine test, similar to a human drug test, that can detect any levels of THC or other drugs.
If not much time has passed since the marijuana ingestion, the veterinarian may induce vomiting. Another option is to orally administer activated charcoal to your dog, which will bind to the toxins in the GI tract and prevent them from being absorbed. However, once the symptoms start to show, it is often too late for these options, and the dog is instead treated with supportive care until the drug wears off.
Supportive care may include
IV fluids to keep them hydrated, help maintain organ function and flush the toxins out of their system quicker
Medications to regulate heart rate and respiration
Anti-anxiety medications to minimize agitation
Close monitoring of the dog’s blood pressure, oxygen levels, and body temperature
Keeping the dog confined to a small, safe and comfortable space, such as a kennel
Keeping the dog away from excessive noise, light, or other sensory stimulation
If you suspect your dog has ingested marijuana, it is crucial you bring them in right away to see a veterinarian. While it is extremely rare for marijuana ingestion to be fatal in dogs, it is not impossible.
If you use cannabis for any reason, be aware of the risks to leaving it out where a curious pug can get into it.
