I first ordered this product when my American Bulldog lacked the nutrition his body required due to a decrease in his appetite. The Vet. didn't expect him to make it past two weeks if his appetite didn't return. I ordered the Cod Liver Oil as soon as I got home, and Domino lapped it up! He is now doing awesome! It regulated all of his digestive issues he has had since puppydome, and his skin/coat are shinier than ever! I works so well that I now give it to all my doggies. I will forever sing the praises of this product!
