Is any amount of THC safe for pets?

No. Dogs and cats are highly sensitive to THC and can experience marijuana toxicosis even at low doses. Choose zero-THC, pet-formulated products instead.

How long does THC affect pets?

Much longer than in people. Effects can last 12–24+ hours because pets metabolize THC slowly.

What should I do if my pet ingests THC?

Call your veterinarian or an emergency clinic immediately and describe what was ingested. Early, accurate information helps direct prompt care.

Are zero-THC hemp products a safer option?

Yes—when they are pet-specific, third-party tested, and include clear weight-based dosing (like Hemp Well). Always follow label directions and consult your vet.

THC and Pets: Why Zero-THC Matters for Dogs & Cats

THC (delta-9-tetrahydrocannabinol) is the primary psychoactive compound in cannabis. While cannabis contains hundreds of additional compounds that may have wellness value, THC is the component that creates a “high.” For pets, especially dogs and cats, THC isn’t just intoxicating—it can be dangerous.

Does THC have health benefits?

In human medicine, THC has been explored for pain relief, appetite stimulation, and certain neurologic conditions. That said, pets are not small humans. Dogs and cats have more cannabinoid receptors than we do, which makes them extremely sensitive to THC and at risk for what veterinarians commonly call marijuana toxicosis. Even small amounts can cause profound effects, and pets metabolize THC more slowly—what might be a 2–3 hour experience in a person can linger 12–24+ hours in a pet.

Bottom line: Do not give your pet THC. Until robust veterinary safety data exist, stick to zero-THC options formulated for animals.

Why THC Is Risky for Pets

Higher receptor density: More CB1 receptors in the brain means stronger, longer psychoactive effects.
Slow clearance: Pets take longer to eliminate THC, extending adverse signs.
Product uncertainty: Human products (oils, edibles, vapes) often combine THC with other actives not evaluated for pets.

Common Signs of THC Exposure in Dogs & Cats

Lethargy, disorientation, imbalance (ataxia), dribbling urine
Glassiness of eyes, dilated pupils, abnormal vocalization
Hypersensitivity to touch/sound, agitation, or tremors
In severe cases: low heart rate, low blood pressure, seizures

If you suspect exposure: Contact your veterinarian or an emergency clinic immediately. Be honest about what may have been ingested—this speeds appropriate care.

Safer Alternatives: Zero-THC Hemp Options for Pets

When you want hemp support without the “high,” choose pet-specific, zero-THC formulas with clear dosing guidance by weight. Hemp Well products are crafted for animals, feature 0% THC, and are tested for quality.

Hemp Well Calm Dog Soft Chews — gentle relaxation support without sedation.
Relief Plus CBD Oil for Dogs & Cats — zero-THC, labeled by weight for easy dosing.
Hemp Well for Cats — cat-focused options with clear administration directions.
Hemp Well for Horses & Bird — species-specific, zero-THC hemp supplements.

Note on human products: Many human cannabis products contain THC (sometimes alongside CBD). Avoid these for pets. Choose pet-formulated, zero-THC options only.

Terpenes caution: Some essential-oil–like terpenes used in human formulas can irritate pets; certain terpenes may be especially harmful to dogs and can be dangerous for cats. Stick with pet-specific products that disclose terpene content and safety.
