They are 3/4 rat terrier and 1/4 Chihuahua
In case if any of you were wondering, I got that combonation because, the owners were going to kill her because they weren't purebred (who knows what that means anyways?) They couldn't get money off of them because they were "mutts". Once again, I'm sorry for the confusion, I should have thought before I wrote.

(Thank you everyone else too for sticking up for me, I didn't have time to type that before!)

Everyone else that was angry, I understand, and I hope I wasn't sounding like a snot thanking them, I'm not trying to call you mean or anything!
