Introduction
Many dog owners wonder if fish is safe for their pets. Fish is a type of meat that comes from the sea, rivers, or lakes. It is rich in protein and healthy fats.

But does that mean all fish is safe for dogs to eat? Not always. Some fish can contain bones, harmful bacteria, or high levels of mercury. Feeding fish the wrong way can cause stomach problems or other health issues. This makes many pet owners question if they should share fish with their dogs at all.
The good news is that dogs can eat certain types of fish when it is prepared properly. Cooked, boneless fish in small amounts can be a healthy treat.
