THC Delta 8 Toxic To Dogs?

Yes, according to websites that sell CBD.

This paragraph brings the whole issue into perspective.

This ran on a web site that sells CBD. Obviously they want to avoid customers changing to THC Gummies. They have a massive investment in a business that sells CBD, which is practically a placebo unless it contains ‘traces’ of THC. 

KEY POINT: While the site does a good job of showing that given in GRAMS per dog, THC full spectrum can be toxic, it fails to remark that a therapeutic dose of Delta-8 Isomer THC is ONE THOUSAND TIMES less.

Keep in mind that a therapeutic dose of pure Delta-8 THC is a HALF a MILLIGRAM per kilogram of dog. I repeat MILLIgram. A thousandth of a gram. Now, read on.

Relievet: “According to the Alameda East Veterinary Hospital, the minimum lethal oral dose for dogs for THC is 3 g/kg. Meaning a 30-pound dog needs to ingest 39 grams* of pure THC to have a lethal dose.”

*(That’s three thousand nine hundred milligrams of a compound that should never be needed MORE than twenty five MILLIgrams! A sixty pound dog maxxes out at 25 milligrams.)

Relievet: “Since cannabis is usually consumed through ingestion or inhalation, the lethal dose of cannabis flower for a 30-pound dog is 195 grams. That is more than a quarter-pound of material a dog would have to eat. THC percentages vary in different strains, so even more caution should be employed if you have weed containing upwards of 20% THC.”

Relievet: “In the case of concentrates, marijuana is distilled down to a concentrated form, and the lethal dose is much lower because of the higher percentage of THC available. In this case, a product containing 80 percent THC would require 48.75 grams of concentrate to cause lethality in a 30lb dog potentially.”

Here, the author provides the useful information that full-spectrum THC can cause untoward reactions when given at SIXTEEN TIMES the therapeutic dose: 8mg/kg versus 0.5mg/kg

Relievet: “In a safety-specific CHE investigation in dogs (17), CBD-only doses up to 62 mg/kg resulted in no adverse events, whereas ascending doses of THC (up to 49 mg/kg) or CBD and THC (up to 12 + 8 mg/kg, respectively) resulted in increasing and medically significant neurologic adverse effects.”

The article references several times that the administration of massive doses of CBD caused no effect. This is not surprising since “actual” studies of CBD show that it takes a month to bind canine ECR cannabinoid receptors in any meaningful way.


CBD Businesses need to either engineer a THC Isomer Gummy, or go out of business. In the meantime, demonizing something as useful as THC Delta 8 is tacky and does a disservice to canine customers.

And so it goes as you cross the internet looking for viable information about THC in dogs. Sites that quickly latch on to articles to re-word, that discuss mega-dosing THC full spectrum as a “bad thing” which is it. Where’s the information that damns THC Delta 8 at therapeutic doses?

So, from this article, you can calculate safe doses of THC Delta 8 Isomer for your dog. Assuming your dog is healthy, and not on competing medications and under the advice of a cannabinoid-savvy veterinarian.

But how does that translate into “how much actual GUMMY does the dog need?
Or, if my dog needs 15mg, how much of a Gummy should I give it?

So this chart is based on the fact that Koi Brand only has two ‘strength’s of gummies. They have a 25mg and a 50mg gummy of Delta 8 isomer THC

NO WE ARE NOT TALKING ABOUT MILQUE-TOAST Flimsy CBD here.

Delta 8 Isomer THC Gummies by Koi Brand FOR HUMANS. If they ever come out with a dog-brand I won’t be recommending them. There is MORE QUALITY CONTROL in the manufacture of human products.

For most companies the idea in pet products is “They’re just dogs, how much could the law suit cost us?”

So get the human product.

Use THIS chart to figure out how many milligrams your pet needs.


And then use THIS CHART to figure out what that translates into as far as a 25mg or 50mg Gummy. Delta 8, Koi Brand for people.
