My two girls..Emilee and Gidget have always gotten along, but never played with each other or gave each other that much attention. Within the last 3 months, they are together all the time and actually play together throughout the day. Shocked me silly, I tell ya. Gidget never wanted to play that much, even with toys. She will be two years old in February and is just now going through her puppyhood.....LOLOL
