That Nobby Salmon Oil is a 100% natural supplement of salmon from Scotland for dogs and cats. It provides a high quality source of essential and unsaturated omega-3 and omega-6 fatty acids. The fatty acids are called “essential” because they can not be produced sufficiently by the body and should be supplied to the organism in sufficient quantity. It can also support the immune system, growth and the cardiovascular system. It comes in a transparent bottle with UV protection.
