Hi Garry,
Sorry to hear about your Dad and the dog. What a piece of work....
Anyway my sister is a dog breeder and is high up the ladder on several national organizations in the States (Rottweiler, Shutzhund, etc.). Maybe she can spread the word and get that breeder at least casually blacklisted? She is absolutely scrupulous, and few people are willing to mess with her anymore...
PM me and tell me the type of dog, place where the deed occurred, and the name if you dare.
I will see if my sister knows anything and might be willing to pass on this information.
Don't know if it would help, but this breeder's reputation needs some adjustment in terms of reality.
