Hi! How old is a male boxer puppy when he will reach Sexual maturity? Mounting as well as... Discharge... ?? I am asking because my guy is 5 months and I noticed a creamy discharge from him.

He also pees a lot and lately sometimes evidentially has accidents in the house as I have discovered...Two pee spots but I had ignored them as I didn't catch him in the act and I wasn't watching him while I was showering (locked him in my bedroom) i was worried at first that he has a bladder infection but then it dawned on me maybe he's an early bloomer...

I never see him mounting or air humping or anything though which is why I am still worried he could have a bladder infection.
