You may be able to find an Animal Shop in the game, Harvest Moon GB.

Before you can purchase any animals, you have to have fodder stored in your silo. Once you've planted grass and harvested it, the
shop owner will allow you to buy animals from him. When you buy your first cow he'll give you a free Cow Bell, which will allow you to take your cows out for a walk on sunny days. Whenever you sell an animal back to him he scolds you and asks that you don't do it again, but you can still continue to do so.
