This is the first time I've had just one boxer. I have always had a male and a female. I wouldn't allow my female to get pregnant. Didn't want any pups. I won't get them fixed though. Right now I have a female. I wanted to get a male, but have been putting it off for some time now. I have been looking for an older male (6 months to a year old). I don't plan on getting one thru a shelter for the above reason.
