Can Dogs Eat Fish? Well, it depends on the type of fish because some fish are safe for dogs and some are not. It also depends a lot on how you prepare fish for your dog.

Best Fishes for Dogs

Fishes who have longer lifespan are not preferable for dogs i.e. Tuna and swordfish, whereas fishes with relatively shorter lifespans are best for dogs i.e. salmon, ocean whitefish, lake whitefish, herring, walleye, flounder, and arctic char.

Due to the constant dumping of industrial waste by industries in water bodies, there is a high concentration of heavy metals, such as mercury, in water. Fishes that live longer tend to have greater mercury build-up in their tissues vs those with shorter lifespans. Fishes with greater mercury content can lead to kidney failure in dogs if they eat them over a long duration of time.

How should you give Fish to Dogs?

Fish is healthy for dogs and is best served cooked, steamed or boiled. It is important to ensure that fish is not cooked in oil, herbs or salt since these can be toxic for dogs.

Following are the precautions you must take while giving fish to dogs:

  1. Fish should be well cooked since they can carry bacteria like salmonella and listeria. These bacteria can make your dog sick and can spread from dogs to humans.
  2. Fish should not have any bones since bones in fish are extremely fragile and can splinter while eating. Splintering while eating or chewing might lead to internal bleeding.
  3. Fishes with long life span should be avoided i.e Swordfish and Tuna.
