10 Best Dog Fish Oils 2025 in the United States

The Zesty Paws Wild Alaskan Salmon Oil is crafted to support the skin and coat health of dogs and cats, rich in Omega-3 fatty acids like EPA and DHA. These fatty acids are vital for maintaining a shiny coat, normal skin moisture, joint function, and immune support. One of its notable strengths is the use of salmon harvested from the Alaskan Bering Sea, which assures a good quality source of fish oil. Moreover, the product has passed the National Animal Supplement Council's quality audit, which speaks to its purity and reliability.

This supplement comes in a liquid form and serves as a convenient food topper, which can appeal to pet owners who prefer it over capsules or chews. Its inclusion of mixed tocopherols (natural antioxidants) is an added benefit for preserving the oil's quality. The provided pump makes it easy to measure and mix with pet food, tailored for pets across all life stages.

Despite these positives, some users might find the strong salmon flavor off-putting, especially if their pets are picky eaters. Furthermore, while the product promotes various health benefits, individual results can vary, and some pets might require a longer period to show visible improvements. Lastly, the product's success heavily depends on consistent usage and the specific health needs of the pet.

This product seems to be a fitting choice for pet owners seeking a reputable Omega-3 supplement to enhance their pets' coat and immune system health, assuming their pets enjoy the taste.

This product is also enhanced with biotin and wheat germ oil, supporting not just skin and coat health but also offering potential benefits for joints and heart health. The liquid form with a pump dispenser makes it easy to add to a pet's food, and its seafood flavor is likely to appeal to most dogs and cats. It's designed to be gentle on sensitive stomachs, which can be a plus for pets with digestive issues.

The product comes in a 32-ounce bottle with a pump for convenient dosing based on your pet’s weight. It is suitable for all breeds and is formulated to help maintain normal skin moisture and promote immune health.
