I've fed canned tuna in the past, but it did give my dogs fairly runny poop, but I've fed canned salmon much more often with no ill effects on digestion.
I'd love to feed canned chicken, but it is more expensive than fresh chicken! Next time I do a trip to costco I think I'll check to see how much they charge for canned chicken.
However, as Barb E. suggested you could try Evangers canned dog food. Seriously, they have products that are real meat. You can see the difference from any other brand of canned dog food. It does not look or smell like dog food! The one that my dog loves the most is called (I know
)"Hunk of Beef", and it is a chunk of beef slow cooked to incredible tenderness. It flakes apart like a roast that has been cooked in a crock pot! They do not add anything to this recipe, it is strictly meat.
If you can find a store that carries it, you should buy one can and see how your dogs like it.
Anyway, I think canned meats are fine to feed as long as they don't have too much sodium. I've seen that some companies will can without salt, but the products are usually more expensive. Of course!
