I simply adore small dogs, especially Chihuahuas. I dearly miss having one. For those like me, who don't want to have biological children, yet needing an outlet for their nurturing instincts and whatnot, having a dog that was bred to be coddled is just what the doctor ordered.

Yes, I'm one of those people who adores putting a nice cozy sweater on her Chihuahua but it serves a practical purpose as well. Chihuahuas are small and easily lose body heat through their small little bodies, so wearing a sweater is a must for them on a chilly winter day. I also love talking baby talk to my dogs, and calling them cute little pet names. It's all part of dog ownership.

But to focus more on the OP, I'd go see a T about this resentment you harbor towards breeds that are made to coddle and nurture. You can work these out without taking out aggression on those innocent babies. It's certainly not their fault.
