Native Pet Omega 3 Fish Oil for Dogs & Cats - Promotes Healthy Skin, Shiny Coat, & Strong Joints - Made with Wild Alaskan Salmon Oil for Dogs – Tasty, Fast-Absorbing Omega 3 6 9 Liquid Supplement-16oz

Native Pet Omega 3 Fish Oil for Dogs & Cats is a liquid supplement made from wild-caught Alaskan salmon and pollock oils, providing a natural and high-quality source of omega fatty acids. It contains a full profile of omega 3, 6, and 9 fatty acids, including EPA and DHA, which are key for supporting healthy skin, a shiny coat, and strong joints. The addition of biotin and wheat germ oil offers extra benefits for reducing shedding and improving dry or itchy skin. Its seafood flavor tends to be well-accepted by even picky eaters, making it easy to add to your pet’s daily meals.

The product comes in a convenient pump bottle, allowing simple, measured dosing based on your dog’s weight. This supplement suits dogs of all breeds and life stages, from puppies to seniors, helping maintain overall vitality and joint comfort. Being made in the USA with responsibly sourced ingredients adds to its appeal for pet owners concerned about quality and sustainability.

One consideration is that the 16 oz size might be somewhat small for larger dogs or multi-dog households, requiring more frequent purchases. Additionally, while the product boasts a broad omega profile, some buyers looking for very high concentrations of omega-3 alone might find it less concentrated than specialized formulas. Nevertheless, it offers a balanced approach for general skin, coat, joint, and heart health in a tasty and easy-to-administer form.

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.

Buying Guide for the Best Dog Fish Oils

Choosing the right dog fish oil can be a bit overwhelming with the variety of options available. Fish oil supplements for dogs are popular for their numerous health benefits, including improving coat health, reducing inflammation, and supporting heart health. To make the best choice for your furry friend, it's important to understand the key specifications and how they relate to your dog's needs. Here are the main factors to consider when selecting a fish oil supplement for your dog.
Omega-3 Fatty AcidsOmega-3 fatty acids are essential nutrients that play a crucial role in maintaining your dog's overall health. They help reduce inflammation, support heart health, and improve skin and coat condition. The two main types of omega-3s in fish oil are EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid). When choosing a fish oil, look for a high concentration of these fatty acids. For general health maintenance, a moderate level of EPA and DHA is sufficient. For dogs with specific health issues like arthritis or allergies, a higher concentration may be more beneficial. Always consult with your vet to determine the appropriate dosage for your dog's specific needs.
Purity and QualityPurity and quality are critical when selecting a fish oil supplement for your dog. High-quality fish oils are free from contaminants like heavy metals, PCBs, and other toxins that can be harmful to your pet. Look for products that have been third-party tested for purity and quality. Certifications from organizations like the National Animal Supplement Council (NASC) can also indicate a trustworthy product. Opt for fish oils that are sourced from wild-caught fish rather than farmed fish, as they tend to have fewer contaminants.
Form of Fish OilFish oil supplements for dogs come in various forms, including liquid, capsules, and chews. Liquid fish oil is easy to mix with your dog's food and is often more cost-effective. Capsules can be convenient for precise dosing and are less likely to have a strong fishy odor. Chews are a great option for dogs who are picky eaters or for those who see them as treats. Consider your dog's preferences and your convenience when choosing the form of fish oil. If your dog is finicky, you might need to try different forms to see which one they accept best.
Source of Fish OilThe source of the fish oil can affect its quality and nutritional profile. Common sources include salmon, sardines, anchovies, and mackerel. Each type of fish has a different balance of omega-3 fatty acids. For example, salmon oil is rich in both EPA and DHA, making it a popular choice. Smaller fish like sardines and anchovies are less likely to accumulate toxins, making them a safer option. Consider the source of the fish oil and choose one that aligns with your dog's health needs and any potential sensitivities.
Additional IngredientsSome fish oil supplements contain additional ingredients like vitamins, antioxidants, or other beneficial compounds. While these can provide extra health benefits, it's important to ensure that they are safe and necessary for your dog. Avoid products with artificial additives, preservatives, or fillers. If your dog has specific health concerns, look for supplements that include ingredients targeted at those issues. Always read the ingredient list carefully and consult with your vet if you are unsure about any additional components.
