Malibu is 3 and we just got a girl puppy 3 weeks ago...Just a little background on Malibu-he is SPOILED and showered with attention. The first 3 days or so was a little iffy. Nothing aggressive, but I just wasn't sure if he would love her. But now they play all day every day. I feel bad for not doing this sooner because they love each other so much! Do it, but just a bit of info I read about...the best combo is boy/girl. Same sex pairs can be less submissive to each other. 2 is definitely better than 1
