I started adding a fish oil supplement, 3v Free Form Liquid, as recommended by my vet (at Integrative Holistic Health in Bolton, MA). My bulldog has had bouts of dry skin with hair loss for most of the summer months mostly on her back. We did all the testing for allergies and ruled out the obvious like ring worm and mites. Her fur was stiff, dry and had lost it's shine. After 2 weeks of the daily top dress of her food, her coat started to become soft and shiny and the circular bare spots sprouted new hair. It has been 4 months now since we began, and she looks fantastic. Like a puppy again. Just wanted to recommend it to my fellow Doggie Group friends. I have no $ interest in the company... lol.

According to the literature:

Fish oil that is "recommended to support the immune system and joint health by helping to reduce inflammation associated with normal daily activity. It also promotes healthy skin and hair coat and provides a concentrated source of beneficial Omega-3 Fatty Acids in a patented free fatty acid form.
