Brewer's yeast for dogs
Brewer's yeast (inactivated Saccharomyces cerevisiae) is a nutrient-dense flake rich in B-vitamins, amino acids and beta-glucans. It is a long-standing, food-based way to support coat condition and appetite — and dogs tend to love the savoury taste.
What it does for your dog
Skin & coat
B-vitamins support skin renewal and a glossy coat.
Energy metabolism
B-complex helps the body turn food into usable energy.
Palatability
Its savoury flavour makes fussy eaters more interested.
Gut & immune
Beta-glucans in the cell wall support gut and immune function.
The evidence
Brewer's yeast is a genuine, food-based source of B-vitamins and beta-glucans that support coat and general condition. Note: the popular claim that it repels fleas is not supported by controlled studies — use it for nutrition, not pest control.
How much does a dog need?
Effective amounts scale with body weight. As a daily guide, given with a meal:
| Dog size | Typical daily amount |
|---|---|
| Small (<10 kg) | ~0.5–1 g |
| Medium (10–25 kg) | ~1–2 g |
| Large (25 kg+) | ~2–3 g |
When to skip it
Well tolerated by most dogs. Use inactivated brewer's yeast, not active baking yeast (which can cause dangerous bloating). Avoid in dogs with yeast allergies, and check with your vet if your dog has skin allergies.
