Can Dogs Eat Tuna?
In moderation — a little tuna is safe, but regular feeding risks mercury accumulation. Stick to small, occasional portions.
Small amounts of tuna are OK — watch the mercury
Tuna isn't toxic to dogs and is a good source of protein and omega-3 fatty acids. However, tuna accumulates mercury at higher levels than most fish. Occasional small amounts are fine, but tuna shouldn't be a regular part of your dog's diet. Canned light tuna has less mercury than albacore.

What to Do
A small amount of tuna is fine. Here's how to feed it safely.
- Choose canned light tuna (less mercury than albacore)
- Feed tuna packed in water, not oil
- Keep portions small — a tablespoon for small dogs, a few tablespoons for large dogs
- Don't make tuna a regular meal — once a week at most
- Avoid tuna with added salt, spices, or sauces
