Hi
I sorta have the same problem as you. I have an 18 month old girl and have just recently got an 8 week old girl also. My oldest Missy would not let the pup Boots near her at first, but she is coming round now and they are playing with each other, I think they will get on great, im just dreading when Boots gets older, i think their gonna be jumping about the place like 2 kangaroos. lol. Well ill just have to wait and see. Good Luck
