Mostly I have had female dogs. Currently we have a male bichon and, of course, now I want to get a sheltie. At first, I thought that I needed to get a female to make sure they get along. But I noticed that some of you have 2or more males. If they are both fixed, are you sure they will get along? I don't want to buy a male and have to get rid of it, if they can't be friends. The bichon we have likes every dog he has ever met, male or female. Also, what about bonding--is it the same regardless of the sex of the dog?
