Can my dog eat tinned tuna?
A little.
Tuna in spring water, drained, in small amounts is fine. In brine or oil it is not.

How much is fineA tablespoon of water-packed fish, once a week at most.
WhySalt is the problem, and tuna is a large predatory fish that carries mercury, so it stays occasional. Sardines in water are lower in mercury.
Already ate it?
