Cannabis (THC) Toxicity in Dogs
Cannabis (THC) toxicity in dogs is becoming increasingly common in the UK as cannabis products become more accessible. Dogs are far more sensitive to THC than humans. Even small amounts can lead to symptoms, such as wobbliness, sedation, dilated pupils and changes in behaviour. All dogs are vulnerable, but young and curious adult dogs are most at risk. Talk to a vet without delay if your dog has consumed a cannabis product.
Cannabis toxicity (marijuana poisoning, THC intoxication) happens when dogs ingest or inhale products containing tetrahydrocannabinol (THC), the psychoactive chemical found in the leaves and flowers of the cannabis plant. Edible cannabis products, such as gummies and cannabis ‘cakes’ are especially risky due to high concentration of THC and the presence of additional toxins, such as chocolate or xylitol (an artificial sweetener). With supportive care, most dogs will recover within 1–3 days, but severe cases and dogs who’ve consumed products containing additional toxins will usually need veterinary hospital treatment.
