Is it permissible to raise a small dog until it grows up to be used for guarding the farm?

It is forbidden to own or raise dogs except out of necessity, such as guarding, which is one of the permissible necessities. It is permissible to raise a young puppy for the purpose of benefiting from it in ways that allow the ownership of dogs, such as guarding, as training a dog can only be achieved through owning it.
