I brought Massimo home at 8 weeks, and never had ANY problems with him or his behavior. I've often wondered what he would be like if I did get him at an older age.....I wonder if he would love me as much as he does now, or if he would be this well behaved. I've met his parents (and he often visits with his sister) and they may be CUTE, but they are by no means WELL behaved. His sister is more aggressive than Massimo...when they get together she likes to "dominate" him.He's such a mama's boy! When she's around, I always end up holding him more..... If I ever get another Maltese, or small breed pup, I'm going to make sure I get an older one though. I was just LUCKY with Massimo.
