I bought for my beloved chow-chow (6 years). A striking result - the coat became bright red. Prior to that, I bought the human drug Omega3 in capsules and squeezed out of the capsule in the feed. Does not smell like fish - only a delicate aroma of meat. Glass bottle. The lid closes tightly. I add in a forage - ok.1 / 2 tbsp in the morning and in the evening. Do not spare money for the health of your favorite pets!
