What Seafood Is Bad For Dogs

Consider adding fresh or processed fish to your dog’s diet if you want to stick to smaller, younger, wild-caught fish because these are typically safer selections.

Safe Fish for Dogs

Dogs can eat a variety of fish, including:

  • Whitefish
  • Flounder
  • Salmon
  • Herring
  • Catfish
  • Cod
  • Whiting
  • Light tuna fish (canned) (canned)

These fish are typically less likely to have severe parasite burdens or high tissue mercury levels.

Can Dogs Eat Sardines?

Due to their small size, sardines appear to be universally recognized as a fish that dogs can safely eat. They can be eaten whole, including the skin and bones. But you should seek out goods that are salt-free and packed in water. Additionally, look for brands that feature the MSC Certified (Marine Stewardship Council) blue fish labels, which denote that the fish in question were caught using sustainable wild-caught fisheries, aiming to have the least possible detrimental impact on nearby marine habitats.

Can Dogs Eat Tilapia?

If properly prepared (skinned, deboned, and just the boneless fillets supplied as food), tilapia can be eaten to dogs. It would be wise to check for products whose labels include the certification of either the Global Aquaculture Alliance or the Aquaculture Stewardship Council as tilapia is a farm-raised, hybridized aquaculture product. Additionally, tilapia caught in Ecuador and Peru has been suggested by the Monterey Bay Aquarium Seafood Watch Program as being “greener farmed and consequently healthier selections.”

Types of Fish That Aren’t Safe for Dogs

Guidelines from the Food and Drug Administration advise against eating the following kinds of fish:

  • Shark
  • Tilefish
  • Swordfish
  • monarch fish
  • Bluefin tuna (canned)

When these fish species are harvested, they are frequently older and larger. Not only are they more likely to accumulate unhealthy levels of mercury in their tissues, but they also frequently have parasites living inside of their internal organs, muscles, and skin.

Fish that has been farmed should typically be avoided as well, especially if it comes from regions with minimal industry standards limiting the kind and standard of the fish’s diet. Additionally, hazardous residual antibiotic levels, dyes, and other possible poisons are more likely to be found in the skin and muscle of farm-raised fish after they have been collected and processed.

Which fish are off-limits to dogs?

Can dogs consume tuna? Yes, in moderation. Only give your dog a small amount of it because it is rich in important fatty acids but also contains significant amounts of mercury and histamine.

Atlantic mackerel is a healthy source of omega-3 fatty acids and is safe for your dog to consume because it has less mercury than other varieties.

What fish can dogs not eat?

It’s time for the naughty list now that we’ve completed the good catch. Unfortunately, not all fish is healthy for dogs. Here are some types of fish and seafood that dogs shouldn’t consume:

Salmon is acceptable when it’s plain, but when it’s smoked, your dog won’t like it because of the high salt content.

As filter feeders, shellfish including prawns, oysters, mussels, and clams can have dangerously high amounts of pollutants such heavy metals. They frequently result in food poisoning. While glucosamine can be found in abundance in green-lipped mussels, there are other, safer ways to offer this joint-friendly vitamin to your dog.

According to Dempsey, fish is used by Purina because it is a good source of many of the nutrients that dogs require. Additionally, fish is not only good for dogs—people also enjoy the flavor of fish.


Fresh tuna has the highest mercury levels despite being extremely palatable. Regularly feeding your dog tuna is sure to have long-term ramifications, as mercury poisoning can have lethal results. However, if your dog accidentally ate some tuna, it won’t hurt them. Just be sure not to regularly feed them tuna.

What about tuna in a can? In addition to chemicals and preservatives that can harm your dog, the particular kind of fish used to produce canned tuna ranks even higher on the list of mercury contaminants. Avoid this since canned salmon is often a bad choice for dogs!

Fish Oil

Fish oil wound up on the list of dietary undesirables after years of dominating the market for omega-3 supplements. Why? Fish oil may contain arsenic, mercury, cadmium, and lead due to the high levels of pollution in our oceans, which can cause canine cancer and irreparable harm to a dog’s nervous system.

Shellfish (Shrimp, Lobster, Crab)

Dogs can eat shrimp, lobsters, and crab that have been cooked and completely cleaned of their shells and unpleasant parts. Dogs can only be fed the meat of shellfish, and only if it is fresh and cooked correctly (no leftovers!). A few nibbles won’t hurt your dog, but it’s not a good idea to give it as a meal. Shrimp are frequently contaminated with poisonous poisons, lobsters are heavy in fat and sodium, and crab flesh has a very high iodine content. There is a chance of allergic reactions even in situations when eating shellfish was a one-time treat. In the end, it’s better to be safe than sorry!

Bivalve Molluscs (Clams, Scallops, Oysters)

If the clams, scallops, or oysters were cooked, even a tiny bite won’t be fatal to your dog. However, feeding them as a meal can result in major issues, and that’s before I even mention the hard shells, which can create problems of their own. These rare bivalves are prized for their ability to filter water, but the toxins end up in their flesh. A bivalve with dinoflagellates in its meat, for instance, can give your dog paralytic shellfish poisoning if they eat it.


The least dangerous aspect of giving your dog sushi is the chance that they could get parasites from the raw fish. Sushi may contain a variety of substances that are unsafe or not suggested for canine ingestion, such as avocado or rice vinegar, depending on the preparation method. Therefore, order takeaway only the next time and save some for later! Fido, I’m sorry!

Fish Sticks and Imitation Crab Meat

Both of these dishes are derived from fish, specifically whitefish species, and a significant amount of carbohydrate. They are not necessarily hazardous, and it won’t damage your dog if they eat a few fish “fingers,” but they are nutritionally worthless. Although there are no advantages to using imitation crab meat or fish sticks in your dog’s daily diet, the low quality of the components may eventually become a problem.

Are shrimp safe for canines?

In addition to being delicious, shrimp are a great source of vitamins and minerals for dogs, including phosphorus, niacin, vitamin B12, and antioxidants. The metabolic functions of your dog depend on vitamin B12, which is also crucial for gastrointestinal health. Niacin, commonly known as vitamin B3, is necessary for a variety of functions, including the synthesis of fat, blood circulation, chemical signaling, and correct enzyme activity. Healthy bones require phosphorus, and antioxidants combat free radicals and slow down the aging of the brain.

Shrimp are a healthy option for dogs on a diet because they are low in fat, calories, and carbs. Shrimp contain a lot of cholesterol, though. This means that while eating shrimp occasionally is a good pleasure, eating too many shrimp might cause your dog’s diet to include excessive amounts of cholesterol.

Does tuna fish harm canines?

The amount of mercury in fresh tuna is significantly higher than that in salmon and tilapia, two other common fish. Too much mercury in the body can lead to mercury poisoning, which can have serious or even fatal health effects.

Our lakes, rivers, and oceans become contaminated by mercury as a result of industrial processes like coal-fired energy generation. Fish then start to collect mercury. The concentration of mercury in a fish’s tissues increases with size and lifespan. Tuna have significant levels of mercury since they are massive, enduring fish.

Consumer Reports, a non-profit, advised people to base their tuna consumption restrictions on their weight. It is better to avoid giving your dog any tuna at all because they are smaller than people and there are no guidelines for how much tuna a puppy may consume safely.

Fish with lower mercury content should be chosen if you wish to pamper your canine friend. The fresh fish that is most frequently used in commercial dog food is also the most secure. Salmon, whitefish, herring, flounder, and Arctic char are examples of this.

If your dog manages to steal some tuna off your plate while you’re not looking, don’t worry too much. Dogs are not poisonous to tuna, and even a small amount won’t result in mercury poisoning.

Make sure your dog isn’t eating your cat’s food if you have both a dog and a cat because tuna is frequently found in wet cat food. Because cats are also prone to mercury poisoning, think about choosing a cat diet that contains different types of fish.
