Hello everyone! So I have a 3 yr old chihuahua and I wanna get another..but I'm afraid my chihuahua 'dottie' won't like her? She hates other dogs I also have a st.bernard mix and she just hates Kim when he gets close her..lol! But she has never meet another chihuahua or ever meet a small dog before actually! So will she like another or am I gonna have to pass up the pup and just have Dottie..
