Is canned tuna healthy for dogs? Tuna is safe to eat in small amounts as a rare treat, but it definitely shouldn’t become a staple food for your furry friend. Like many fish, tuna is a good source of protein and omega-3 which are essential in your dog’s diet to keep them healthy.
How much can tuna can I give my dog? If you are feeding your dog fresh tuna, it is safe to feed your dog one or two small bite size pieces of tuna once or twice a week. You should do this a little bit less often for small dogs and can afford to give large dogs a little more, as their weight largely dictates how much they can consume.
What happens if a dog eats tuna? “Tuna can contain high levels of mercury,” Whittenburg says. “If a dog consumes large amounts, it could cause mercury poisoning.” And mercury poisoning can cause irreversible neurological and renal damage.
What canned tuna is best for dogs? To keep it as safe as possible, only feed your dog canned tuna that’s packed in water and not oil, and that doesn’t have any added salt. Albacore tuna will be fine in low amounts, but low-mercury picks like yellowfin are an even better way to go.
