Okay, a friend is a hobby byb. My old mutt was lonely and acting like she was on her last leg and he gave me a puppy. I raised the puppy and my old dog has plenty of life left in her, she likes puppies and dog companionship. But the mom of the puppy was a bit too game, there was fight over a hambone and my old dog needed some tending at the vets, my fence was old, he'd been wanting that dog back, the mom got hit by a car, the father of the puppy was grieving himself ill so I gave him the puppy back. People would see that 6 month old puppy and pull their wallets out but he wouldn't sell him. He bought the granddaughter of the father from a litter. I really wanted her, she was/is something special herself. I sent 40lbs of great puppy food home with him just for her. But a cousin lost a dog and the kids were crying and he gave them puppy. The cousin's job had him off working and the man's wife didn't feed the puppy right between 4 and 6 months. We made a deal. I said I'd do my best for the dog and agreed to let him line breed her grandfather one time for some pups next year. His old dog is really something special and a large part of why this puppy has such great conformation so don't lecture me about the line-breeding please. The man's uncle raises some fine dogs with great bloodlines and conformation and her grandfather is one of his. I grew up on a farm and my dad raised ****-hounds and some curs for catch dogs, pigs and bears. I could teach him a few things and make him better with dogs and he knows it. The feeding of dogs is a hot topic with me since the puppy was skinny although that was not his doing. I have been focused on health, conformation, and temperament. I have not researched color at all with regard to pitbulls. His dog is a blue and my dog is blue fawn. It is my understanding that breeding these two dogs can cause skin problems in the pups and future breeding should not be done between two dilutes. Is there enough of a health risk to the pups to go back on my word and not produce the litter I promised him? They are both healthy dogs with great conformation and in the world of byb that's almost a miracle.
