Outbreeding of dogs
Outbreeding is the way in which males of different systems mate with females (that is, between dogs that do not share a common ancestor) although they belong to the same breed. When breeding in this way, because there is less commonality and dogs with different genetic factors mate, it is more difficult to obtain puppies with the same nature and fixed shape. However, if the strengths of both male and female breeds are clearly demonstrated, it is possible to breed a new breed.

However, no matter what kind of peeling method is used, the skin should be spread flat, nailed to the plank, and dried and taken off.
