Nope they get pick and that's it, but he might say ill only let you bread with mine for 2 pups or it could be anything really like 50 up front and pick then it's up to you if you wanna go through with it or not. Just remember, so you don't get burned that without you and your dog, even after birth are gunna have to take care, feed and give shots and take to the vet if needed. So if he wants more I would say no. It's nothing but a totally free puppy to him not you. Keep that in mind. But on the other hand if his dog a bad azz dog you might want to hear his counteroffer, if he's willing to not do it. It's all up to you. You hold the ACES here
Depends. If they are breeders and youre using their dog they may have a set contract that stipulates their terms for using their breeding male. Their terms may include more than one pup from the litter. That should be in place of or at least off set the normally astronomical price breeders usually request. I thinks thats fairly normal. Breeders dont breed for free. If they are charging a huge fee AND want more than one pup then you need to negotiate or find a different breeder.
It should all be decided mutually before studding takes place. If they're not paying costs and you're doing all the work, just borrowing their dog, yes, just pick of the litter, any pup of their choosing, should be sufficient. If you are splitting costs, it depends how you want to split it up. That being said, think about if this is what you really want. Puppies are expensive if you do it right, good food, vet care, other supplies, a lot of time. And keep in mind that for every puppy from a "backyard breeder" that is found a home, about 200 die in a shelter. Closer to 500 if you're talking about pits. If you really feel you need the "puppy experience", contact your local shelters. Tell them when they have a litter of newborn pups who need fostering, you're available. Problem solved, everyone wins.
