Dogs and THC: What Every Dog Parent Should Know

By Guest Author 2 min read published: January 29, 2026

As cannabis becomes more accessible, many pet owners have questions about safety. You might be curious if the products that help humans relax or manage pain can do the same for your four-legged family members. You need to know how dogs and THC interact to keep your pet healthy. The short answer is THC isn't safe for dogs, and this guide explains why.

What Is THC?

Tetrahydrocannabinol, or THC, is the main chemical in the marijuana plant that causes a high. It’s different from CBD, which is a non-psychoactive compound found in hemp. Although you might see CBD products marketed for pets, products with high levels of the psychoactive agent THC are meant for human systems only.

How Does Cannabis Affect Dogs?

Dogs have a high number of cannabinoid receptors in their brains. These receptors make them more sensitive to the chemical than humans are. A small amount that a person might not even feel can make a dog very sick.

Because they’re so sensitive, veterinarians agree that recreational cannabis isn't appropriate for pets. So, if you’re wondering about how much THC is safe for a dog, the safest answer is none. The risk of poisoning is higher with edibles, which often contain other toxic ingredients such as chocolate or xylitol.

Signs Your Dog is Intoxicated by Cannabis

Marijuana toxicity in dogs usually shows up between 30 minutes and a few hours after they eat or inhale the substance. Look for these common signs:

  • Stumbling or looking wobbly, often called ataxia
  • Appetite loss
  • Glassy or dilated eyes
  • Sensitivity to loud noises or sudden movements
  • Vomiting or excessive drooling
  • Sleepiness or lethargy

Does Pet Insurance Cover Cannabis Intoxication?

It’s vital that your dog only eats foods that are safe for dogs. Veterinary treatment for toxicity often requires fluids, blood tests and monitoring, which can lead to an expensive bill. Most pet insurance plans cover accidents, including the ingestion of toxins. 

A solid dog insurance plan allows you to focus on getting your pup better instead of worrying about the cost.

FAQs About Whether THC Is Safe for Dogs

Is THC Bad for Cats?

Cats can experience cannabis toxicity just like dogs can. However, they’re often better at hiding their illness, so you might not notice signs right away. In some cases, they may act agitated or drool excessively.

Can Cannabis Intoxication Be Treated in Dogs?

When treating cannabis intoxication, veterinarians focus on treating the symptoms because an antidote doesn't exist for THC. The vet might give your dog IV fluids to keep them hydrated and medications to stop vomiting. Additionally, they’ll keep your pet warm and quiet until the effects wear off.

How Can I Prevent My Dog From Getting Intoxicated?

To prevent your dog from getting anywhere near your THC, keep cannabis products in a high, locked cabinet. Make sure you throw away packaging in a secure trash can that your dog can’t open. Be sure to ask guests to keep their bags or coats out of reach, as dogs often find treats in pockets.
