It can take a little while for them to get use to another dog, especially if she is use to being the only one. When we brought our Chloe home, it took our only dog Hugo a while to get use to her. He really hated her at first, but after a couple of months they were best friends!! Hugo would lick her little head until she was soaking wet... it was soo cute! Just dont force her to like the new pup, it will just take a little time.
