    Guide to Finding the Best Krill Oil Supplements for Dogs

    If your dog suffers from allergies, it may be tricky to find the best remedy to relieve their scratchy skin. Adding foods high in omega fatty acids, such as krill, is a fantastic approach to improving your dog’s general health. Below are some aspects to consider when choosing a krill oil supplement.

    Product Type

    There are many types of krill oil for dogs that you can buy. Some are basic, only benefitting the skin and coat, and others are advanced, improving other areas of health like joints and immune systems. You should determine what kind of product you need and then buy the one that suits your dog’s condition. For example, the basic one is the best choice if you only want to focus on allergies. However, more advanced options will offer more benefits, but usually at a higher price.


    As with any food for your pet, it’s essential to look at the ingredients in a krill oil supplement. In particular, you’ll want to look for the presence of omega fatty acids. Supplements that include fish oil and salmon oil in addition to krill oil will likely have the most omega fatty acids. Other important aspects include EPA, DHA, and astaxanthin.


    Krill is an excellent source of nutrients that will unquestionably improve your dog’s health. However, some products work better than others. The effectiveness can be determined by ingredients, how it’s made, and what form it’s in. When in doubt, look at the product reviews to see how successful a supplement is.

    Treat Form

    For dogs, krill is primarily available as treats or liquid oil. It depends on your preference because both are effective for dogs.

    Supplement in Liquid Form

    You can easily incorporate liquid supplements into your dog’s regular diet. All you have to do is pour the oil onto your dog’s food. It usually has no flavor and blends in with the food. Given that this product comes from the sea, it will naturally have a fishy flavor. Oil is usually better purchased in pump form because pouring it can be messy.

    Supplement in Chews

    Chews may be a more convenient and effective way to give your dog krill oil. Although chews can have a variety of flavors, the most common are cheese, bacon, or a natural fishy flavor. Dogs are more inclined to indulge in these supplements because they’re carefully made to appeal to their taste buds and they look like treats.

    This kind of krill can also be used as rewards. Your dog will believe they’re receiving a tasty treat, but that treat can improve their health too.

    FAQs Related To Krill Oil Supplements

    What is krill oil?

    Krill oil is a natural extract from tiny, shrimp-like creatures called krill. Krill swim in dense flocks in the world’s oceans, feeding on microscopic seaweed. They’re the most abundant food source for other marine species, and their vast flocks provide millions of tons of food for everything from fish to whales.

    Is krill oil better for dogs than fish oil?

    Yes, krill oil is better for dogs than salmon oil, especially regarding omega-3 absorption rates. Fish oils, such as salmon oil, contain omega-3 fatty acids in the form of triglycerides. On the other hand, krill oil for dogs has phospholipid omega-3 fatty acids.

    Why do people give their dogs krill oil?

    Krill oil is a fantastic source of omega-3 fatty acids. Specifically, krill oil has a particular kind of polyunsaturated fat. Thus, krill oil has good essential fats that our bodies require.

    Omega-3 fatty acids are known to be good for human health, but it turns out that dogs can also benefit from them. The only way for a dog to get omega-3 fatty acids is through food or, in this case, a convenient supplement made from krill because a dog cannot make them on their own.

    Happy Golden Retriever


    With so many options, deciding which krill oil supplement is best for your dog can seem daunting. We recommend that you always discuss your options with your pet’s veterinarian, as they will understand your pet’s needs best.

    Hopefully, the list we created will help you narrow down your options. Omega-3 fatty acids support your pet’s immune function, muscle recovery, joint health, and heart health. If your dog has dry or flaky skin, hot spots, or a dull or weak coat, adding omega-3 fatty acids to their diet will likely help. So, if your dog’s skin and coat health isn’t improving on its own, consider trying one of the best krill oil supplements for dogs.
