Is CBD legal for dogs in Washington?

Short answer: yes. Here's what Washington law actually says — the THC limit, whether your vet can recommend it, and how to buy for your dog without stepping wrong.

The short answer

Hemp-derived CBD (under 0.3% THC (the federal hemp limit)) is legal for dogs in Washington under the 2018 Farm Bill.

Can your vet recommend CBD in Washington?

Washington is more permissive than most. It's among the states that let veterinarians discuss and steer owners toward CBD more openly, rather than keeping them silent. Your vet still works within federal limits, but you can generally have a real conversation — so ask directly, and bring the graded evidence and your dog's weight-based dose to the appointment.

Marijuana vs. hemp CBD in Washington

People conflate these, so to be clear: recreational and medical marijuana are legal in Washington — but that's a separate issue from your dog's CBD. The CBD you give a dog is hemp-derived, with little to no THC. Marijuana and THC are toxic to dogs and cause real poisoning; never give a dog a marijuana or high-THC product, regardless of Washington's cannabis laws. Stick to hemp-derived, pet-specific CBD.

Can I order CBD for my dog online in Washington?
Yes — hemp-derived CBD ships legally to Washington. Look for a batch-matched COA, potency within 10% of the label, and a THC line under 0.3%.
