100% Wild Sardine Oil A bowl of oil shines and ensures your four-legged friend receives a good dose of omega-3: wild-caught sardine oil. The fact that fish oil contains a lot of omega-3 is probably nothing new, but did you know that our sardine oil contains the most? That's because sardines live in the wild. Omega-3 is good for: skin problems, heart and blood vessels, a dull coat, better concentration, increased food intake, flexible joints, improved fertility, and finally, it has an anti-inflammatory effect. A valuable addition for every loyal snout.
