It all depends if you want to breed or not to be honest with you.

However I look at it as if I was the male dog, for example: if you were the dog in question and was with a girl and you was ready would you rather be allowed to do what you wanted or be kept away.

We had one of each sex and let them breed the first time but as I wasn't really experienced with breeding dogs I was a bit nervious but thats just me.
