Domestika; I know the breeder you are posting about. Yes, she is a puppymill. A few police agencies use her dogs because she talks a good talk and when you produce as many dogs as she does; some have to turn out o.k.. The dogs I have seen of hers with the police departments (and granted that's not all) are ****; I've seen them work. She's had 1 or 2 good dogs; a couple that could have been better had she not browbeaten them into submission. A lot of her titles on her dogs aren't real either, seriously -- a lot of what she writes seems to be wishful thinking. She had parvo in her yard (which granted anyone can get; but she is a major importer/flipper of dogs). She keeps and breeds some very sketchy dogs (your Nova is now one of them). GSDs are tricky as a breed anyway; maybe try to get an adult that you know doesn't have any health issues. My trainer (who has worked with this breeder's dogs) has now put down 4 different GSDs (different lines) due to; brain tumour; spinal myelopathy, OCD/Pano/osteoporosis, epilepsy and now her puppy has one testicle. Getting a good working GSD is a long row to hoe. My friend is just happy her pup isn't lame; never mind the single testicle.
Don't feel too bad; lots of people have been caught out by her breeding tactics; we (trainer friend and I) never recommend her dogs to anyone.
