8 Omega-3 Rich Foods That Reduce Inflammation in Senior Dogs

Salmon is one of the richest natural sources of omega-3 fatty acids, especially EPA and DHA. These healthy fats support joint lubrication and help reduce stiffness. Cooked, boneless salmon can be a delicious and safe treat for senior dogs. Make sure it’s free from added seasoning, oils, or sauces that may upset their stomach.

Sardines are packed with omega-3s and are also an excellent source of calcium, protein, and vitamin D. Because of their small size and soft bones, they’re easy for older dogs to chew and digest. You can offer canned sardines packed in water as a topper on your dog’s regular meal. Avoid sardines in oil or with added salt.

Mackerel is a smaller, oily fish that’s full of anti-inflammatory omega-3s. It also contains selenium, a nutrient that helps protect cells from oxidative damage. Cooked, plain mackerel fillets can be mixed into your dog’s food. As always, avoid giving raw fish or fish prepared with spices.

Flaxseed

Ground flaxseed is a plant-based source of ALA, another form of omega-3. While dogs don’t convert ALA as efficiently into the active forms (EPA and DHA), flaxseed still offers some anti-inflammatory benefits. It also adds fiber to support digestion. Sprinkle a small amount of ground flaxseed over your dog’s food for a nutritional boost.

Chia Seeds

Like flaxseed, chia seeds are a plant-based option that’s rich in ALA omega-3s. They’re also loaded with antioxidants, protein, and fiber. Soak chia seeds in water before adding them to your dog’s food to make them easier to digest and reduce the risk of choking.

Green lipped mussels are a natural powerhouse of omega-3s, glucosamine, and chondroitin, which support joint repair and flexibility. These shellfish are particularly helpful for dogs with arthritis or age-related stiffness. The Green Lipped Mussel and Chondroitin Hip and Joint Supplement (on Amazon) is a convenient way to give your dog the benefits of mussels in chewable form.

Omega-3 Salmon Oil Supplements

If your dog doesn’t eat enough fatty fish, supplements can be an easy and effective option. Salmon oil is one of the most concentrated sources of EPA and DHA. It promotes a healthy coat, supports cognitive function, and reduces inflammation. iHeartDogs Norweigan High Omega-3 Salmon Oil (on Amazon) is specially formulated for dogs and can be added directly to their food.

Krill

Krill is a small crustacean that contains omega-3s in a form that’s easily absorbed by the body. It also includes astaxanthin, a potent antioxidant that adds an extra layer of anti-inflammatory support. While not as widely used as salmon oil, krill oil is a good alternative for dogs with fish sensitivities or allergies.
