Confused about Mercury and Heavy Metals when it comes to feeding your dogs fish?

Omega-3 fatty acids, low fat, and high protein: We all know the benefits of eating fish.

On the other hand, high levels of mercury and other toxins in polluted environments cause many health professionals to question the safety of seafood in general.

Fish, when prepared properly, can provide many major health benefits to your dog’s diet, but if not done properly, it can easily go wrong.

If you want to add a fish treat to your dog’s diet, not every type of fish should be eaten by your pup.

Before feeding your dog a fish-rich meal, it is important to understand the benefits of fish and the types of fish that are safe to feed your puppy.

Here’s what you need to know.

Should You Feed Fish to Your Dog?

Should You Feed Fish to Your Dog?Even if there was no ongoing debate about the benefits and healthiness of marine foods, the question remains: is it safe for a dog to eat fish, shrimp, or any other type of seafood?

The short answer is that dogs can eat some types of seafood, but it all depends on the species and preparation method. Unsurprisingly, dogs do best with fish, whereas clams, shellfish, shrimps, and other aquatic critters usually come with a set of warnings before serving.

Here are some general pointers as to what to look for in fish before you feed it to your furry baby:

  • Lifespan: Always go for shorter-lived species of fish. In species with longer lifespans, such as tuna, mackerel, or sea bass, high levels of heavy metals and toxins accumulate over their lifetime.
  • Size: The same rule applies when it comes to size. Smaller fish have less mercury, while bigger specimens accumulate as they eat massive quantities of other fish.
  • Bones: Fish that are hard to clean bones are a safety risk for dogs. Brittle bones can tear through your dog’s intestine wall and pose a choking hazard.

Of course, even with seafood and fish that are safe for dogs, moderation is key. While your pooch might benefit from an occasional meal, this type of food shouldn’t make up most of their diet.

Benefits of Fish for Dogs

Benefits of Fish for DogsDogs love the smell of fish. You probably know this if you’ve ever eaten fish and your dog won’t move from your side.

Not only do fish smell great to dogs, but they are also a very healthy alternative for pets with food sensitivities caused by common proteins, such as chicken or turkey.

Adding fish to your dog’s diet can also provide them with a rich source of omega-3 fatty acids.

These essential fatty acids are also found in avocados and have been associated with supporting your puppy’s healthy, beautiful skin and coat.

Finally, fish is low in fat, making it an excellent alternative for supporting weight.

Risks of Feeding Seafood to Dogs

In some cases, the risks may outweigh the benefits. Not all seafood is rich in the nutrients needed in a dog’s diet, and some can actually be harmful to your dog.

  • Presence of toxins, heavy metals, and other pollutants
  • Commercial pet food containing fish may contain harmful preservatives
  • Risk of bacterial infection such as salmonella and listeria (if raw or not cooked properly )
