If it&;s for the sake of prestige, it&;s definitely a male dog. It&;s not as simple as being bigger. A good breed can be about half as big. A male dog can be sterilized one month after the first time, but why do you want to sterilize him? Have you asked the dog how he feels? On the other hand, if you were sterilized, would you like it? Besides, there is no need to sterilize it. If your dog breed is pure, it is not your dog&;s business to give birth to a dog. You will also be given money after it is matched. Another point is that an adult Alaska with pure breed can never hold back and must be strictly trained.
