I really want to get my second B. I've had Diego for a year and he is about 2 1/2 or 3. I think he would love a playmate and I would really like another one too. If not this year for sure next year. So I need to know, what is better to get already having a male- a female or another male, or does it not matter and just depend on the specific dogs. I would like your opinion. Thanks!!!
