THC vs. CBD in Dogs: What Pet Owners Need to Know

As cannabis-derived products become more mainstream, pet owners are increasingly curious about their potential benefits and risks. But when it comes to dogs, the distinction between THC (tetrahydrocannabinol) and CBD (cannabidiol) is crucial.

What's the Difference Between THC and CBD?

THC is the main psychoactive compound found in marijuana. It's responsible for the "high" and is toxic to dogs. Even small amounts can cause serious side effects like disorientation, tremors, seizures, or coma.

CBD, on the other hand, is non-psychoactive and has shown promise in treating conditions like anxiety, arthritis, and seizures in pets. Many veterinarians are now recommending CBD products specifically formulated for animals.

Is THC Safe for Dogs?

No. THC is considered toxic to dogs. According to the ASPCA, ingestion can lead to vomiting, seizures, tremors, and even death in extreme cases.

Can Dogs Have CBD?

In moderation and under veterinary guidance, yes. Studies show CBD may help dogs with arthritis, anxiety, and inflammation. However, it must be THC-free and pet-specific to be safe.

Symptoms of THC Toxicity in Dogs

Loss of coordination
Vomiting
Excessive drooling
Tremors or seizures
Low body temperature

What to Do If Your Dog Ingests THC

Seek immediate veterinary care. THC toxicity is not something to treat at home. Be honest with your vet — it could save your dog’s life.

Legal Status in the U.S. and Canada

U.S.: THC is illegal federally and in most states for use in animals. CBD is federally legal but not regulated by the FDA for pets. Use only vet-recommended, tested products.

Canada: THC for pets is not legal. CBD for pets is only legal if it’s approved by Health Canada, which limits availability. Be cautious of unapproved products sold online.

Choosing Safe CBD Products for Dogs

Look for 3rd party lab testing
Confirm 0% THC content
Use only pet-formulated products
Start with the lowest dose

Natural, Legal Alternatives

Try these calming or pain-relieving options:

Herbs like chamomile and valerian root

FAQs

Can my dog get high from secondhand cannabis smoke? Yes, and it can be toxic. Always keep pets away from smoke.

Is CBD addictive for dogs? No, CBD is non-addictive and non-psychoactive.

Safe Products to Try

If you’re interested in calming products that don’t include cannabis, try:

Crafty Beasts' Fetch Canine Pale Ale
CharDOGnay – a wine-inspired dog beverage

These are alcohol-free, herbal-based, and pet-safe beverages that offer novelty and calming effects without the risk.

Conclusion

THC has no place in your dog's diet — it's dangerous, illegal, and potentially fatal. CBD, when used appropriately, offers promising benefits but still needs more research. Always consult your veterinarian, understand local laws, and use pet-specific products from reputable sources.

Treats That Should Be Marketed for Both Dogs and Cats

Treats That Should Be Marketed for Both Dogs and Cats Because good ingredients don’t need a species label. We live in a world where dogs steal cat treats and cats nibble on dog jerky—and the truth is, many treats don’t need to be separated by species at all. Especially in multi-pet homes, the overlap in healthy, species-appropriate ingredients is huge. So why are treats marketed so differently? Why the Divide Exists Short answer: marketing and money. The pet industry thrives on duplication—more labels, more packaging, more sales. But if you read the back of a high-quality single-ingredient cat treat and compare it to a dog treat… they’re often identical. Dogs are scavenging carnivores, cats are obligate carnivores, and both benefit from meat-first, low-carb, additive-free snacks. Treats That Are Perfect for Both Dogs and Cats 🐟 Freeze-Dried Fish (Salmon, Minnow, Whitefish) Why it works: High in Omega-3s, supports joint and coat health, and irresistible to both speci...

But did you know that cold weather can also affect your dog’s weight? When the snow starts to fall and temperatures drop, many of us notice changes in our dogs — from lower energy to dry skin. One change that can sneak up on pet parents is weight fluctuation . Dogs may gain or lose weight in the winter depending on their activity level, metabolism, and environment. Understanding these seasonal shifts can help you keep your pup at a healthy weight year-round.

Extra calories: Many owners add “comfort foods” or extra treats during the holidays, leading to calorie overload. Indoor l...

Why Dogs Should Never Consume Alcohol

Why Dogs Should Never Consume Alcohol Updated for 2025 It may seem like harmless fun to let your dog have a sip of beer or wine during a celebration, but even small amounts of alcohol can have serious — even fatal — effects on your dog. Unlike humans, dogs process alcohol inefficiently, making them extremely sensitive to its toxic effects. Understanding the science and dangers behind alcohol consumption in dogs is critical to ensuring your pet's health and safety. Why Alcohol is Toxic to Dogs Alcohol (ethanol) affects the nervous system, liver, kidneys, and brain. Dogs lack the metabolic enzymes to safely break down ethanol, even in small amounts. This can lead to ethanol poisoning within just 30 to 60 minutes of ingestion. Their smaller size means it takes far less alcohol to cause damage compared to a human. Common Sources of Alcohol Exposure Many dog owners don’t realize how many household items contain alcohol. These include: Beer, wine, ...
