Can dogs eat liver?

Caution icon
Caution — cooked, small amounts only

Plain cooked liver is nutrient-rich and most dogs love it, but too much causes vitamin A toxicity. Use as an occasional treat.

The full picture

Liver (beef, lamb, chicken) is a powerhouse treat — extraordinarily rich in protein, iron, vitamin A, B vitamins, and copper. Dried liver is a classic high-value training reward. The catch: liver is so high in vitamin A that regular large amounts cause vitamin A toxicity (hypervitaminosis A), which damages bones and joints over time. Rule of thumb: liver should never be more than 5% of total diet. Cook plain (boil or bake, no seasoning), or buy freeze-dried liver treats. Raw liver carries bacterial risk.
