Koi Naturals CBD Pet Spray
Koi Naturals CBD Pet Spray
Koi Naturals CBD Pet Spray is a 500mg broad-spectrum hemp extract in a coconut oil base, in a pump bottle you spray onto food or directly into your pet's mouth. It is the only delivery format in Koi's pet line that is not a chew, which matters more than it sounds: a spray lets you scale the dose to a five-pound cat or an eighty-pound dog off the same bottle.
Koi calls it veterinarian-formulated and makes it without gluten, dairy, artificial colors, flavors or preservatives. It is broad spectrum, which is the right call for pets because it removes the THC.
Quick Verdict: Who Is This For
Buy this if you have a small animal, a cat, or a picky eater. A 30-pound dog and a 9-pound cat need very different amounts of CBD, and a soft chew gives you one fixed dose per piece with no easy way to give a half. A spray gives you per-pump control.
Skip it if you have a large dog who happily eats a treat. The chews are cheaper per milligram at the 60 and 120 count sizes and far less fuss than pinning a squirming animal to spray its mouth.

What This Does Well
Dose control
A pump is the smallest reliable unit of CBD you can give an animal. With chews you are stuck at one piece or two. This is the difference between guessing and measuring for a cat or a toy breed.
Broad spectrum, no THC
Dogs are far more sensitive to THC than people, and THC toxicity is one of the more common cannabis-related vet visits. Broad spectrum removes that variable entirely.
Two ways to give it
Spray it on food if your pet is cooperative, or into the mouth if they pick around it. A chew only works if the animal eats the chew.
Pros and Cons
Pros
- 500mg in a format you can actually titrate
- Broad spectrum, so no THC to worry about
- Works for cats, which most CBD pet lines ignore
- Coconut oil carrier is well tolerated
- Free of gluten, dairy and artificial additives
- Three-pack and five-pack cut the per-bottle price meaningfully
Cons
- Koi does not publish a per-pump milligram figure, so you are dosing by bottle math
- More expensive per milligram than the 60 and 120 count soft chews
- Some animals object to being sprayed in the mouth
- No flavor options if your pet dislikes the light taste
- Coconut oil can separate; needs a shake before use
How to actually dose it
Koi does not print milligrams per pump on the label, so work it out from the bottle: 500mg across the full bottle. Start low, hold for several days, and increase only if you see nothing. The common starting point vets use for CBD in dogs is roughly 0.2 to 0.5mg per kilogram of body weight twice a day, but this is not veterinary advice and there is no established dose for pets in the way there is for approved drugs. If your animal is on any medication, especially anticonvulsants or NSAIDs, talk to your vet before starting, because CBD competes for the same liver enzymes.
On drug testing
Not applicable to pets, but worth stating for the person holding the bottle: this is broad-spectrum extract with THC removed, so there is no intoxicating dose in it for your animal. Do not substitute a human full-spectrum tincture for a pet product. THC is genuinely dangerous to dogs.
Where to Buy
Koi sells this direct at koicbd.com. The five-pack is the best per-bottle price if you have multiple animals or a large dog; the single bottle is the sensible way to find out whether your pet will tolerate the spray at all before committing.
Koi’s published refund policy gives a full refund on returns started within 90 days of purchase, and 50% back between 91 and 150 days. Shipping is free on orders over $69, and current discount codes are on our Koi coupon page.
FAQ
Can I use this on a cat?
Yes. Koi lists it for dogs and cats, and the spray format is the practical reason to choose it for a cat over a chew. Cats need much smaller amounts than dogs, and you cannot meaningfully split a soft chew.
Will this make my pet high?
No. It is broad spectrum, which means the THC has been removed. There is nothing intoxicating in the bottle.
How long before I see anything?
CBD is not a fast-acting sedative. Most owners who report a change describe it over one to three weeks of consistent daily use, not on the first dose.
Is it third-party tested?
Yes. Koi publishes a certificate of analysis for each batch, searchable by the lot number on the bottle.
Is it better than the soft chews?
Different jobs. The spray wins on dose control and works for cats. The chews win on cost per milligram and on ease if your dog will eat anything.
