THC/CBD Poisoning in Dogs and Cats
THC/CBD POISONING IN DOGS AND CATS
THC/Cannabis poisoning in pets is becoming increasingly common, especially since cannabis products such as edibles, oils, gummies, capsules, and v**e products are more widely available in homes.
Dogs are particularly at risk because they are attracted to the smell and taste of edible products. Even small amounts of THC can cause significant illness in pets. There is no current veterinary therapeutic indication for THC in animals and exposure by oral or inhalation route leads to clinical signs at low doses.
Common signs of THC poisoning may include:
• Sleepiness or appearing “out of it”
• Wobbling, stumbling, or inability to walk normally
• Vomiting
• Dilated pupils
• Dribbling urine
• Agitation, anxiety, or unusual behavior
• Low heart rate
In severe cases, pets can develop seizures, breathing difficulties, coma, or other life-threatening complications.
CBD products are often marketed as “safe” or “natural,” but they can still cause problems in pets, especially if taken in excessive amounts or contaminated with THC. Many over-the-counter cannabis products are not well regulated, making accidental poisoning a real concern. Human on-site urine drug tests (THC) often return false negative results for pets so are minimally useful for diagnosing THC poisoning in veterinary settings.
If you suspect your pet has ingested cannabis or CBD products:
• Stay calm
• Remove access to the product
• Contact your veterinarian immediately
• Do not attempt home remedies unless directed by a veterinarian
Most pets recover well with prompt veterinary care and supportive treatment, but early intervention is important. For pets ingesting a small to moderate dose of THC the
prognosis is good; full recovery is expected within 3 days. Conversely, pets ingesting high doses of THC or ingesting synthetic THC (Spice/K2) have a worsened prognosis for recovery and death has been reported.
Please help keep your pets safe by storing all cannabis products securely and out of reach — just as you would medications or toxic household items. Pet Poison Helpline (855-764-7661), an animal poison control center based out of Minneapolis, MN is available 24/7 for pet owners and veterinary professionals that require assistance treating a potentially poisoned pet.
