In recent years, more and more pet owners have started supplementing their dogs’ and cats’ diets with fish oil. Whether it is for skin allergies, excessive shedding, joint degeneration, or cardiovascular support for senior pets, fish oil has become one of the most popular nutritional supplements available today. However, many pet owners do not realize that the true value of fish oil lies not in the oil itself, but in the Omega-3 fatty acids it provides. EPA and DHA are the key nutrients responsible for most of the health benefits associated with fish oil supplementation.
