I was so surprised to read your post about nasty Chihuahuas. I've got tons of friends or neighbours who have a couple each or even just one and they are the sweetest ,most cuddly little dogs . I've actually never seen a nasty Chihuahua, that's why your post surprised me. I've seen some that thought they were huge and macho and would bark to warn someone was at the door but as soon as you go in they beg to be petted.
