I have a Shih Tzu and a Yorkie. They don’t have Seborrhea, but I add organic coconut oil to their food. They love it, will eat it right out of my hand. It has a lot of positive health benefits for dogs, as well as humans, but what I’ve noticed with my Shih Tzu is that his coat is softer than it’s ever been. I attribute that to the coconut oil. I am not a health-food nut, but I’ve read a lot about the benefits of coconut oil for dogs-and there are many! My dogs HATED Dinovite too, I quit using that. I also use coconut oil on their foot pads, to moisturize them—search on-line-the benefits of coconut oil for dogs. It may just help the Seborrhea too–I hope so.
