Some daily exercise will help also. I liked to add a couple tablespoons of desiccated liver in the dog feed as well. A antibiotic treatment is not a bad idea. That Hampton's Boze dog (sibling to J. Johnson's Rage) that C. Middleton had was hitting and missing. Later sold to F. Jacobs, and when bred got no pups. Jacobs called the previous owners and wanted to return the dog and get his money back. In the meanwhile took Boze to his local Veterinarian and dog was given a antibiotic treatment and got some pups when bred to his Jacobs Hog dog. This was told to me by the M. June. Cheers
