Many on this site (myself included) use NuVet, it really works wonders on their coats. I'm sorry I don't have experience with this but I hope your baby is feeling better soon!
@michaelsbroly Starting him on NuvetPlus, and giving him a tsp. working up to a tablespoon of plain active culture yogurt would help his skin and immune system,too.
“It came to me that every time I lose a dog they take a piece of my heart with them. And every new dog who comes into my life gifts me with a piece of their heart. If I live long enough,all the components of my heart will be dog,and I will become as generous and loving as they are"
