First (because it's driving me nuts) bread is what you eat. Animals are bred.
Onto the breeder issue. Breeding for 'ball drive' is a load of junk. There are a million other things I'd like to hear a breeder tell me they're breeding for. Ball drive? Whatever. Next issue- why take generations of 'police dogs' and breed to a white GSD for "calmness"??? It sounds like this breeder doesn't know what they're doing in their breeding. If you haven't bought a pup from them, DON'T. I'd also like to see proof of the 'generations of police dogs'. There are sleazy breeders out there that will say all kinds of junk, and people buy it without checking it out. Most shepherds love balls. Over the years, I've seen so many pics of shepherds with tennis balls (or other balls) in their mouths I began to wonder if they weren't born with a ball in there, lol! Seriously, though, I don't think this is a reputable breeder. I've been wrong before, though. I don't like what they're telling you, though, or what they're putting together to breed.
