Can Dogs Eat Fish Sticks?

Fish has long been celebrated as an excellent source of protein for humans. Its nutritional benefits, especially from oily fish, can be a good source of omega-3 which can lead to a healthy coat. Yet, many dog owners ponder: can their four-legged friend enjoy fish sticks?

Understanding Fish Sticks

Fish sticks, typically made of white fish such as cod, haddock or pollock, are usually breaded and deep-fried. Although the taste of fish appeals to many, the additives in fish sticks can be a concern for our canine companions.

While some human cuisines favor raw fish, it’s essential to note that feeding raw fish to dogs, just as it does to humans, can pose risks, including harmful bacteria and parasites. Most fish sticks are fully cooked so this should not be a major concern.

So, how much fish (in the form of fish sticks) is safe for dogs?

Fish Sticks: The Good, The Bad and The Fishy

Fish — Most fish sticks use white fish or fish fillets. Fish is an excellent source of protein and essential fatty acids. However, the type of fish matters. While fresh fish like arctic char or ocean whitefish can be beneficial, others like king mackerel and albacore tuna might have high levels of mercury.

Breading — Fish sticks’ outer layer, despite adding to the taste of fish, is loaded with added salt and doesn’t offer any nutritional benefits. This breading, especially if consumed in large quantities, can contribute to various health conditions in dogs. This is particularly true if the fish stick breading is flavored with spices that can be harmful to dogs.

Frying — This process, though enhancing the flavor, introduces unhealthy fats. Overconsumption can lead to heart disease and other health issues. Some fish sticks are baked instead of fried eliminating this as a potential issue.

What dog owners should know about fish sticks

  1. Salt and mercury — Fish sticks, especially those made from larger fish, can contain high amounts of salt and mercury, posing a risk for mercury poisoning and other medical conditions.
  2. Garlic, onions and harmful bacteria — These ingredients, often found in human food including plant-based meat products, can wreak havoc on a dog’s health. Garlic and onions can cause gastrointestinal upset and even anemia. Meanwhile, raw salmon and undercooked fish can carry harmful bacteria causing salmon poisoning disease.
  3. Small bones are a choking hazard — Fish bones, especially small bones in certain kinds of fish, can be a choking hazard or damage the dog’s internal organs or your dog’s mouth.
  4. Allergies — Just like humans, dogs can have food allergies. An allergic reaction to fish, although rare, can manifest, impacting the immune system.

Benefits of feeding fish to dogs

While fish sticks may not be the best choice for dogs due to their processed nature, fish, when prepared properly, can be a great addition to your dog’s diet. Fish is a healthy source of protein and provides essential nutrients promoting a healthy skin and coat. Other benefits include:

  1. Variety — Different types of fish, especially shorter-lived species like sardines, can offer healthy nutritional profiles.
  2. Essential nutrients — Fish provides vitamin B, vitamin D, amino acids and omega-3 fats. These are not just beneficial but an important part of a home-cooked diet for dogs.

Many commercial dog food brands, with the endorsement of veterinary nutritionists, use fish as a primary ingredient. They ensure safe fish species are used, devoid of high levels of heavy metals. Brands such as Inukshuk’s Marine 25 formula can provide a good source of protein for your furry friend.

How to introduce fish to your pup’s diet

Small portions — As a general rule of thumb, introduce any new food, including fish, in small quantities. Observe for any allergic reaction.

Chose cooked versus raw — Always offer your dog cooked fish over raw to avoid harmful bacteria. Avoiding added salt and spices is crucial.

Types of fish dogs should eat — Shorter-lived fish species are safer due to their small size and reduced exposure to contaminants. Chose wild-caught varieties when possible to avoid the feed given to farm-raised fish.

So, can dogs eat fish sticks?

If you’re inclined to give your dog fish sticks, do so in moderation. Make sure there are no harmful spices, herbs or other ingredients in the breading of the fish stick first and remember that too much salt can lead to serious health problems for canines.

If you want to add the benefits of fish to your dog’s diet, it’s best to choose plain cooked fish rather than processed fish sticks. Canned sardines, mackerel, anchovies or salmon are much better options than commercially produced fish sticks coated in breading that offers no added nutritional benefits to your pup.

Dehydrated fish treats or salmon jerky are much more suitable fish options for dogs that they’re sure to love. A seaweed supplement can even be a better choice for introducing some of the health benefits that come from the sea to your dog’s diet.


While fish sticks can be introduced into a dog’s diet, pet parents must tread with caution. The health benefits of fish are many, but fish sticks, with their additives, pose challenges. Always prioritize your dog’s nutritional needs, ensuring they receive the best types of fish without harmful additions.

As always, consult a veterinary nutritionist before making substantial changes to your dog’s food or introducing them to the delights of fish for the first time.
