We created our Fish Oil as a do-it-all supplement for your dog or cat! It all starts by supporting a healthy skin and coat. But the benefits don't stop there. Fish oil is also known to promote immune function, cardiovascular health and joint strength. Even better, Fera's Fish Oil contains the highest amounts of EPA and DHA Omega-3 essential fatty acids per teaspoon compared to other leading brands, making it the go-to fish oil for your pet. No additives, no fillers and no toxins!
