Yeast tablets are not only healthy for your dog, but they help your dogs coat. They aid in healthier hair growth and prevent fleas and other pests both on the dog and in his living spaces. ie: bed, couch, door mat etc. They make excellent doggie treats and come in a variety of flavors in your finer pet shops if your dog doesn’t like the naturally flavored ones. – My dogs liked all the varieties I bought for them.
