chihuahuas are little vibrating machines. My aunt had one and it would always shake. The stupid thing never would stop shaking, it was ridiculous. I hate them, they are very vicious and territorial. Get a mastiff/GreatDane mix. My cousins had one and it is my favorite dog ever.
AHH THERE IS MY POODIE DOGG!1`:francesco::francesco::francesco:~ (we called him poodie, but his name was judah) :bucky!:

Its head was so big we could play basketball with it and it could hold the basketball in its mouth, no joke.
