Cosmo (my big ole 2.5 yr old Cav) has finally warmed up to Buster (3.5 month old Cav). I was worried about Cosmo as he was totally stressed for a while. I still think that he has further to go, but he's heading in the right direction.
The one thing that I don't remember is how old Cosmo was when he stopped growing. The size difference now is huge, as Cosmo weighs around 27 lbs and Buster about 4.5 lbs. How old typically do Cavs grow until?
