I can relate to not being able to control two dogs. I have a JRT mix and a shepherd mix (both rescues, both spayed), and there is no way I can walk both at once. They wrap the leashes around each other, and me. My shepherd has been thru obedience training, but she only walks nicely when it's just her. She's a goof ball, and if there is someone to play with, all training goes out the window.
Also, I don't see anything wrong with "backyard" breeding as long as you care for the dogs correctly and make sure great homes are found. My parents bred poodles when I was a kid, and the puppies were raised in the kitchen, in a family environment with lots of love and attention - even though they weren't show quality... I would buy from a "backyard" breeder like my parents over a "real" breeder who raises their pups in pens. I don't understand why people get so bent about it. There will always be both irresponsible pet owners, and responsible pet owners, no matter where they get their pets from.
