1 you cosisin's dog has has multiple litters that means he is a back yard breeder. Get on line and do some research on puppies, no 8 week old puppy is still on milk. You need to learn a little about dogs before the puppy comes home. You feed twice a day in the same place. Good quality puppy food is the best to feed. 2-3 times a day. The food you choice will tell you how much to feed by the dogs weight. Ask you BYB cousin what he feeds, then start moving to a better food, slowly. (BYB's don't feed good food) Look for one the has no by byproducts, meat as the first ingredient, no corn, wheat, or soy. I'd also suggest you do some research on back yard breeders and the number of dogs that die each year in shelters from these bad breeders, and try to talk you cousin in to getting his dog spayed and stop the deaths. Step one with your puppy will be getting spayed or neutered.
