"Can I give my dog hemp?" is one of the most-asked hemp questions. The short answer: hemp seed and hemp seed oil are safe and nutritious for most dogs and cats. CBD products are a different category with separate rules. This article keeps the two distinct.
The two categories: keep them separate
Hemp products for pets fall into two regulatory and biological categories that often get conflated in marketing:
- Hemp seed and hemp seed oil: nutritional, considered food. Safe for cats and dogs in modest amounts.
- CBD and broader cannabinoid products: regulated. In Canada, CBD for animals is legal only when prescribed by a licensed veterinarian under the Cannabis Regulations. Most "hemp pet" products sold without prescription are seed-based, not cannabinoid-based.
This article covers category 1. For category 2, talk to your vet.
Hemp seed and hemp seed oil for dogs
Why it works
Dogs use the same essential fatty acids humans do: linoleic acid (omega-6) and alpha-linolenic acid (omega-3). They cannot synthesize either. Hemp seed provides both in a moderate ratio along with high-quality protein. The GLA content is particularly relevant for dogs with skin conditions.
Common reasons owners use it
- Skin and coat improvement (the most-reported benefit)
- Joint comfort in older dogs
- Picky-eater appetite stimulant (the smell is appealing to most dogs)
- Protein supplementation for senior or active dogs
Dosage guidelines
| Dog weight | Hemp hearts (daily) | Hemp oil (daily) |
|---|---|---|
| Under 5 kg | 1/4 teaspoon | 1/4 teaspoon |
| 5-15 kg | 1/2 teaspoon | 1/2 teaspoon |
| 15-30 kg | 1 teaspoon | 1 teaspoon |
| Over 30 kg | 1-2 teaspoons | 1-2 teaspoons |
Start with a quarter of the listed amount for the first week and observe stool consistency. Loose stool means too much oil; reduce and reintroduce slowly.
How to give it
- Drizzle hemp oil on kibble or wet food at room temperature.
- Sprinkle hemp hearts on top of food.
- Mix into homemade dog treats (do not heat above 165°C).
Hemp seed and hemp seed oil for cats
Cats are obligate carnivores and have lower fat conversion efficiency than dogs. They benefit from omega-3 supplementation but tolerate plant sources less well. Most cats accept small amounts of hemp oil mixed into wet food but turn away from hemp hearts (texture, not flavour).
Conservative dosing for cats:
- Under 5 kg: a few drops of hemp oil daily, working up to 1/8 teaspoon
- 5-7 kg: up to 1/4 teaspoon daily
- Discontinue if vomiting, loose stool, or refusal to eat.
Important cautions
- Hemp seed is not catnip-like or psychoactive. Whole hemp seed and hemp oil contain only trace cannabinoids well below pharmacological thresholds.
- Hemp foods for humans are NOT the same as cannabis-infused edibles. Edibles containing THC are toxic to dogs and cats and should be kept far out of reach.
- Talk to your vet before adding any new oil or supplement to a pet with pancreatitis, liver disease, or food allergies.
- Watch overall fat intake. Pets prone to pancreatitis may need extra caution with any added oils.
- Store properly. Rancid hemp oil is unpleasant for pets and humans alike; refrigerate after opening.
What about hemp protein powder for dogs?
Generally safe in small quantities mixed into food. The amino acid profile complements meat-based dog food. Stick to a teaspoon for medium dogs daily; more is not better. Cats should not be given concentrated protein powder routinely.
Buying for pets
- Use food-grade hemp products meant for humans rather than pet-marketed versions; they are usually cheaper and identical in content.
- Choose organic if available, since pets often consume relatively larger doses by body weight than adults do.
- Check that the product is hemp seed or hemp seed oil, not "hemp extract" or "phytocannabinoid-rich oil," which suggest CBD inclusion.
