The canned tuna can be made by cooking and “infused” with herbs and spices. While this can make them particularly tasty for people and delicious for salads, never feed your dog canned tuna that contains other spices or seasonings, as they could cause ill health.

Mercury in tuna

A lot of our garbage and pollution end within the waters. Metals like mercury and lead are introduced into our oceans via erosion and rain, rivers, and human sludge and build up in the tissues of sea creatures that call it their home.

The longer a fish’s life spans the greater amount of these heavy metals accumulate within them. It is because they consume some amount of mercury each time they eat that can’t be removed.

Tuna is a massive and long-lived fish, which is why it has higher levels of mercury than different species. It is more likely to live in the ocean, eating a lot of smaller fish, including the mercury in those other fish. Certain species of tuna contain various quantities of mercury. For instance, skipjack tuna is tiny and contains more mercury, three times lower than bigger species such as Albacore.

When you or your dog consume, tuna and a bit of mercury gets added to your food. In the long term, it’s not a major issue. But, if you or your pet eat a lot of tuna over a short period of time, you’ll take in excessive amounts of mercury and get poisoned.

If your pet shows symptoms of poisoning following a meal, like tremors or excessive drooling, consult your veterinarian immediately.

To prevent the danger of mercury poisoning, it’s best to feed your dog tuna in moderate amounts. If you’re concerned about mercury levels in your dog’s diet, consider feeding them other types of fish, such as salmon or whitefish. These fish provide the same benefits in terms of nutrition but contain much less mercury and thus don’t pose the same dangers as tuna.

If you have a big dog, you should never feed them more than one can of tuna in the time of the week, and never offer them a can of tuna every single week. Smaller dogs have less tolerance to eating and therefore should be eating less, perhaps half a can in the course of a week. Whatever what size your dog is do not allow them to consume a complete can of tuna at once.

If you do give your dog tuna, you shouldn’t give them more food for several weeks. Larger dogs may take tuna back sooner than smaller breeds. However, most owners tend to err on the safe side and would rather keep tuna for a treat.

To be safe, you should avoid giving your pet tuna every day. A small amount of tuna added to their meals every few weeks should not cause harm. If you’re making your own tuna sandwich or pasta bake, keep a small portion of fish to pamper your dog with. You could also give your dog the cod, salmon and mackerel as well!
