Cannanine Review: Ask Your Vet, Not the Internet
Cannanine sells THC-free CBD oil for dogs and cats, priced from $29.99 to $69.99 by strength, alongside supplements aimed at joint health and anxiety. Pet CBD is a category with genuine early veterinary research behind it and almost no regulation in front of it. This review has no weight-loss angle to offer and will not invent one — but it does carry a safety warning that matters more than anything else on the page, because the mistake it describes kills dogs.

Verdict: A reasonable product in a badly regulated category, and the THC-free formulation is the right call. Dogs have a far denser distribution of cannabinoid receptors than humans and are markedly more sensitive to THC, so a product formulated to exclude it entirely is meaningfully safer than a full-spectrum alternative. The veterinary evidence for CBD in dogs is genuinely promising in osteoarthritis specifically, with less support elsewhere. The real issue is category-wide: pet CBD faces no mandatory potency testing, so third-party lab reports are the only assurance you get.

Never give your dog a human cannabis or CBD product
Many human edibles and some CBD products contain xylitol, which is severely toxic to dogs at small doses and causes rapid hypoglycaemia and liver failure. Human THC products are also far too strong for a dog and cause a distressing toxicity that veterinary emergency rooms see regularly. Chocolate in edibles compounds the danger. If your dog has eaten a human cannabis product, call a vet or an animal poison control line immediately — this is an emergency, not a wait-and-see.
Dose by your animal's weight and start low. Higher-strength bottles are better value per milligram only if the strength suits your dog.
What veterinary research actually shows
The most solid evidence for CBD in dogs concerns osteoarthritis, where controlled studies at Cornell and elsewhere have reported improvements in comfort and activity. That is a real finding in a specific condition and the reason vets take the category seriously at all.
Evidence for anxiety, seizures and other commonly marketed uses is thinner. Some early work exists, but it does not support the confident claims that pet CBD marketing tends to make. Elevated liver enzymes have also been observed in some dogs on CBD, which is a reason for veterinary oversight rather than self-dosing indefinitely.
Why THC-free matters so much for dogs
Dogs have a much higher density of cannabinoid receptors in the brainstem than humans do, which makes them far more susceptible to THC toxicity. Signs include severe incoordination, urinary incontinence, sensitivity to sound and light, and in serious cases collapse.
A product formulated to be THC-free removes that risk, which is why it is the single most important specification in pet CBD. Verify it on the certificate of analysis rather than taking the label at face value.
Talk to your vet first
This matters more than in human supplements because your animal cannot report side effects. CBD can also interact with medications your dog may already be on, and a vet can check that.
Some vets remain cautious about discussing CBD depending on their state's regulatory position, but most will engage with the question directly. If your dog is on anything for pain, seizures or anxiety, that conversation is not optional.

Look elsewhere
Anyone dosing a pet without veterinary input, particularly if the animal takes other medication. And anyone here for human health content.
Frequently Asked Questions
Is CBD safe for dogs?
Generally well tolerated in studies to date, with elevated liver enzymes reported in some dogs, which is a reason for veterinary oversight. THC-free formulations are important because dogs are far more sensitive to THC than humans. Talk to your vet, especially if your dog is on other medication.
Can I give my dog my own CBD oil?
No. Human products may contain xylitol, which is severely toxic to dogs, and human THC products are dangerously strong for an animal. If your dog has eaten a human cannabis product, contact a vet or animal poison control immediately.
What does the research show for pet CBD?
The strongest evidence is in canine osteoarthritis, where controlled studies have shown improvements in comfort and activity. Support for anxiety, seizures and other marketed uses is considerably weaker.
How much does Cannanine cost?
From $29.99 for lower strengths up to $69.99 for higher concentrations. Choose strength by your animal's weight rather than by price per bottle.
Considering Cannanine?
If your vet agrees CBD is worth trying for your dog, a THC-free product with a verifiable certificate of analysis is the right specification. Never give an animal a human cannabis product.
