Whole mackerel is an omega-3-rich superfood for dogs that supports joint health, cognitive function, and a glossy coat. It can be fed raw as part of a balanced whole-prey diet or fed fully cooked and deboned. Always feed in moderation, as oily fish is calorie-dense.

Mackerel is packed with high-quality protein, Vitamin D, Vitamin B12, and essential Omega-3 fatty acids (EPA and DHA). These nutrients reduce inflammation, making it an excellent dietary addition for senior dogs with arthritis or active dogs needing joint support. 

Raw (Whole-Prey Diet): Advocates suggest feeding raw whole fish is highly natural and that raw fish bones are soft and safe to digest.
