It is acceptable for dogs to eat tuna or tuna salad as long as you feed it to them in moderation. Like any other animal it is important that they eat the type of food that is best for them on a regular basis, though there are certainly a lot of nutritional benefits to eating tuna for both people and animals.

One of the best things about tuna in particular is the fact that it usually contains a fairly low amount of mercury and has a lot of omega-3 fatty acids in it which help to prevent against heart disease as well as other things. Just make sure that you feed your dog the kind of tuna that is kept in water and not oil.
