You could say my dog got "lucky" when it comes to this. He was born with only 1 testi so he didn't have the aggressiveness problems you find on young male dogs and since he's in a pretty safe place where we know he can't escape(he can try but we built some good stuff to prevent him from escaping and he stopped trying years ago) we know he won't go around impregnating other doggers around the block :^)

You might think, hey don't you take him out? Sadly we can't since in the past few years it has turned pretty unsafe around where I live and a friend of mine was walking his dog around and a thief came up to him with a gun and he got scared of the dog when he was stealing and shot the dog :-( since that day I never took him out again...
