How safe is fish for your dog?
So long as the fish is not contaminated and is cooked appropriately, most fish is healthy and safe for your dog to eat.
However, you don’t want to feed certain parts or feed your dog fish that has been seasoned, smoked, or salted.
It also depends on the type of fish that you are feeding. Generally, fresh fish is a great source of nutrients and helps build a healthy immune system.
What are the health benefits of fish in a dog’s diet?
Fish is healthy because it contains a range of healthy fats, vitamins, and minerals. All fish are a great source of protein and amino acids. Some, like salmon, are a great source of Omega-3 fatty acids.
Fish skin contains collagen, and the flesh is a good source of vitamins D, B2 (riboflavin), B12, calcium, phosphorus, iron, zinc, iodine, healthy enzymes, and potassium.
Fish is one of the best sources of essential fatty acids, which is perfect for your dog’s health. That’s why so many commercial dog foods are including fish and why nutritionists recommend it.
What parts of Fish can your dog eat?
Cooked fish skin is a treat for your dog, and some pups absolutely go crazy for fish skin.
Fishbones, fins, and tails are a big no-no, however. The bones and spikes can impale your dog’s digestive system or can become a choking hazard.
Dogs can eat fish heads, but with a few exceptions. They must be cooked, and only some fish are acceptable, such as salmon. Also, avoid fish heads if your dog hasn’t regularly been eating fish.

How should you feed Fish to a dog?
Dogs cannot eat raw fish. Not only can it make them sick, but if they carry certain parasites or bacteria, it can kill them.
On the other hand, cooked fish is fine as long as it has been deboned and cleaned properly. However, fried, battered, or breaded fish is too fatty and should be avoided.
The same thing goes for frozen fish sticks. These aren’t very nutritious and aren’t healthy for your pup.
Canned fish is fine so long as it isn’t packed with added salt or sugar. The best way to prep fish is to bake it, grill it, or broil it. If you need to add oil, make sure you only add a small amount.
What types of fish can dogs eat?
Not only are sardines tasty and safe for your furry friend, they are high in omega fatty acids, selenium, and copper but low in heavy metals.
A small amount of tilapia is acceptable, but make sure you are purchasing from a reputable source.
Many dogs love catfish, but again, be aware that some catfish come from dirty water. Buy from a reliable source.
Cooked or canned tuna is an excellent option for your pooch. Don’t choose canned fish that contains added salt, however. Learn more in our article “Can Dogs Eat Tuna?”
Salmon, especially wild-caught, is one of the best fish for dogs. It is lower in contaminants and high in omega 3 fatty acids, b12, and selenium.
Avoid smoked salmon or salted salmon, however. Remember that fish should always be cooked.
Raw salmon can cause salmon poisoning, which is caused by a fluke called Nanolhyetus salmincola, and it can be deadly.

Anchovies, sardines, mussels, and herring are all sustainable and nutritious and are a good part of a balanced diet.
How much Fish can your dog have?
A little fish goes a long way. Too much, and you’ll make your dog sick or cause them to become obese since fish and fish oil can contain a high concentration of calories.
Check with your vet for specific recommendations for your particular dog and the type of fish you’re feeding.
In general, fish shouldn’t make up more than ten percent of your dog’s diet, according to the AKC. Too much fish can cause health problems and negate the health benefits of fish. Too much can cause illness or pancreatitis.
Can Fish be harmful to dogs?
Although fish can be very healthy, there are some instances when you’ll need to use caution. For instance, just as humans can ingest toxic metals from eating fish, so can dogs.
Some fish have high mercury levels. This can cause serious problems in high enough doses. Mercury poison can cause central nervous issues, which appear as weakness or disorientation.
Other fish are contaminated with industrial waste or other chemicals. Some fish carry parasites or bacteria such as salmonella or listeria. Not only can that make your dog sick, but it can make you sick, as well.
Types of Fish that aren’t safe for dogs to eat?
Generally, the higher the fish is on the food chain, the more mercury it will have in its flesh. Think shark, tuna, mackerel, and swordfish. High levels of mercury can be incredibly damaging.
Other fish can be infested with industrial waste. Eel, bass, cod, and flounder are particularly susceptible.
Finally, raw fish can contain parasites that can make your dog extremely ill. Always cook your fish.
Allergic Reaction to Fish
It’s rare for dogs to have an allergic reaction to fish; however, it’s not impossible.
If you notice your dog is constantly scratching their skin or paws, they keep getting diarrhea or vomiting after eating; they might have food allergies.
Try removing fish from their diet to determine if fish is the culprit in their allergies. If it is, your pup should recover from their allergies once you take it our of their diet.
How can you add fish to your dog’s diet?
Fish can be given as a stand-alone treat, or you can add it to their food. Some dog foods contain fish, usually whitefish or salmon. Make sure the fish is boneless and cooked whenever feeding fish.
How to prepare fish for your dog
