I have an unfixed male dog 4 years old, and we recently acquired a female puppy. We don't want them to have puppies.
My question is if I need to fix both of them, or if I can get away with fixing one or the other, and if so, which is better. I understand that the procedure is simpler for the male. I'm more looking for information about how the animals will deal socially. E.g., will the unfixed male drive a fixed female insane (or possibly even hurt her)?
I don't want to start a discussion about why the male is un-neutered. My answer boils down to not feeling great about removing his family jewels. Let's just leave it at that.
