OP, I'm glad you've decided to neuter/spay your dogs. The rest of this isn't for you, you sound like you are becoming more knowledgeable and honest with yourself about the repercussions surrounding breeding animals.
Selzer....now that you know the bitch was from a convicted and arrested puppy mill, you still going to commit to your usual diatribe of "this one litter isn't going to be the downfall of the breed." Because in my humble opinion, this is the exact situation and thinking that occurs over and over again within this breed that is a major contributing factor to it's "downfall." What's worse, in my humble opinion, is a breeder, such as yourself, coming on and defending/supporting this type of thinking, instead of giving advice and knowledge on why this isn't the ideal way to go about getting another dog like the pet. If I go back into your posts and count how many times you say, "this one litter isn't going to be the downfall of the breed," I bet we'd have a hefty amount of dogs/puppies on our hands.
I guess you and I will never see eye to eye on what a "reputable" and "responsible" breeder is. In my opinion, it goes beyond the actual breeding itself, and flows over into educating those who don't know any better....not supporting putting pets together because this one litter "won't contribute much to the downfall of the breed." I know you didn't say that in this thread, in this thread you instead blindly defended someone putting two dogs together with little to no knowledge of pedigrees, strengths/weaknesses, experience, genetic issues and how genetics are passed down (including the trait they are hoping to duplicate), etc....
You are supporting creating an entire litter of puppies, in hopes that maybe one will be what they need. Even that is a blind guess, because you can't tell at 8 weeks whether a dog will alert to seizures. They already have three dogs, only one of which is doing what they need....and the lack of neutering and spaying is creating major issues between all the dogs....the most major being the adult male growling and cornering a human toddler. I took your posts as a, "oh it's okay, he's probably just crazy because of all the hormones running around." I don't care...what matters is, a child was in danger, the situation wasn't controlled, and now there are issues. Thank God this isn't a worse situation, ie he attacked the child.
However, this>>"he only growled once today" doesn't make me feel much better. My adult male dog growls at my four year old child he get's his clock cleaned....he does more than growl or worse, corners the child, he's gone...and not to a police officer friend's. No one who works with my husband, including the police canine handlers, would take a dog that think's it's okay to do this with children...nor would any of them take a dog from a litter like this for anything other than, hopefully, a family pet that doesn't get aggressive with children.
OP, I truly appreciate your honestly and self reflection on this entire situation. I really hope you don't have 10 puppies on your hands on top of everything else you are dealing with. If you do, please find a local breeder to assist you. Someone with hands on experience, not strictly internet advice, will give you a world of help.
Good luck!
