I think I have my husband finally convinced that Emma needs a playmate. (At least he doesn't argue when I show him potential candidates on petfinder.com) Any suggestions on how to know if a dog is the right one and getting the two adjusted to each other. We are looking at one that is about the same age as Emma, probalbly a rescue. Does gender matter? (I've heard that different gender from different litters work best) Any way to tell if, even though they may be skittish together at first that they will eventually get along. Emma gets along great with my mom's chihuahua and begs to play with him. (even though he wants nothing to do with her) However when I have taken her to the local pet supply store (they allow you to bring your dog in) she seems fearful of other dogs even when they are obviously friendly with her. (In fact she seems more interested in the more timid ones she meets) Any and all advise would be appreciated in this important decision.
