CBD for the Great Dane

Q: How much CBD should I give my Great Dane?

For a giant dog in the 110–175 lb range, the trial-based figures are roughly 25–40 mg per dose to start (twice daily), 75–119 mg for the standard daily range, and about 200–318 mg as a single dose before a stressful event. Weigh your dog and use the calculator for the exact number, and start at the low end for the first week.

Q: Is CBD safe for a Great Dane?

CBD's canine safety record is the strongest part of the evidence — including a 26-week daily-dosing trial. The known signals are drowsiness, soft stool, and elevated ALP liver values at higher doses. THC is toxic to dogs, so use only pet-specific whole-spectrum products. If your Great Dane takes other medication, talk to your vet first. Full safety guide .

Q: Will CBD sedate my Great Dane?

At studied doses, CBD isn't a sedative — trials describe reduced stress behaviors, not a knocked-out dog. If your Great Dane seems flattened, the dose is too high or the product isn't what its label claims (check the COA).

Q: Does CBD actually help Great Dane anxiety?

Honestly: promising, not proven. One placebo-controlled trial found a single dose lowered stress markers during separation and car travel; the fireworks trial came back negative. We grade all of it on the evidence page — the science is the same regardless of breed; the dose is what changes with your dog's weight.

Anxiety triggers, weight-based dosing, and the honest evidence — tuned for a giant dog in the 110–175 lb range. No hype, just the numbers from the actual trials.

How much CBD for a Great Dane?

Every clinical trial doses by body weight, so a Great Dane (110–175 lb) lands in these ranges. Start low for the first week, give it with food, and dial in the exact milligrams with the calculator.

Starting dose

25–40 mg

twice daily · week 1

Standard daily

75–119 mg

twice daily · ongoing

Single event

200–318 mg

once, ~2h before

Ranges reflect the 110–175 lb weight span for the breed (0.5 / 1.5 / 4 mg per kg from Gamble 2018, Hunt 2023, Bradley 2022). Weigh your dog for the precise dose.

Anxiety in the Great Dane

Gentle giants that lean on their people; separation and noise stress are common. Breed temperament is real — a large study of over 13,000 dogs found meaningful breed differences in noise sensitivity and fearfulness — but the dose doesn't change with breed, only with weight. What changes is which triggers you're managing.

For a Great Dane, the situations most worth reading up on:

Separation anxiety — the best-studied use case (a single 4 mg/kg dose lowered stress markers).
Fireworks & thunder — where the evidence is weakest; read before you rely on it.
Car & travel stress — measured directly in the 2023 trial.
Restless sleep — no direct trials yet; here's the honest extrapolation.

Which product for a giant dog

The oil is the most precise way to hit a Great Dane's exact milligrams — you can dose to the drop. Treats are easier on the road but fixed at 5 mg each, which suits larger dogs less precisely — you may need several.
