I am fairly new to breading BP's, but in my opinion as it would me nice to borrow, lets say a Sunset the time needed to quarantine and the entire breeding process it would probably be better to just buy the animal. Especially when you add in the trust factor. I believe it is easier for dogs or horses because the breeding time is predictable and doesn't take most of the year and in most cases you don't have to leave your animal in someone else's care.
