Can Dogs Be Friends?

Now I have to wonder if dogs can really be friends.

I have had Jada for 7 months and she is very attached to me. Now we have this new baby rat terrier in our house and, at first, Jada seemed to like her and kind of treated her as a play toy. I thought it was really cute.

Three weeks have passed and Jada seems to not care for Maggie too much these days. She has been biting at her and playing really rough. Maggie is starting to show nervousness when Jada comes charging at her. This is not the way it is supposed to be! I was hoping that we could just all get along.

Jada still sleeps with me every night and Maggie sleeps in her room. Shouldn't that be enough to prove to Jada that she is my number 1 dog? I love Maggie too and they really need to learn that I have enough love for both of them.

What does an owner do? Should I just move out?
