Male Rottweiler & Mating

Question
Hi, I have a 2 year old male rottweiler.  He disappeared a week ago for a morning, but came back.  Then disappeared for a whole day, but came back.  He has been gone now for 4 days...I've heard it has something to do with mating season...is this true and what are the chances that he will come back?  PLEASE HELP!!

Answer
Hi Helga

A intact male will wander further when a female is in heat, and can be gone for days at a time. However, the chances of him catching brucellois or a STD from a female that you know nothing about or become fatally injured rise every time he leaves home increases.   That is a chance I wouldn't take with my animals.   Do him a favor by either having him fixed or penning him.
