BastardPup is just over 5 months old. Initially we were uncertain about neutering as he has a very good blood line, but a) he's a pet and not a show dog and b) his stumpy tail would be a dealbreaker anyway.
So, we need to plan to get him neutered, but I have no idea when we should be doing this. Previous DHounds were adopted intact aged 5 years and neutered within a month in a vain attempt to calm them down.
What is the current advice?
