NutriDrops
There are no standard forms....you can search on google for contracts..protecting the puppy is your most important item on that contract. Making sure that who ever adopts your kids are the best homes possible...I have even gone to perspective homes and checked myself. Remember, new families are wanting to a reputable breeder and will question you, however, you still own those pups and you've got to feel good about the families....go with your gut, if it doesn't feel comfortable, trust your judgement.
