Was your cell phone set to vibrate last time you saw it? :-)
It could be cold, nerves, fear, or low blood sugar. Ask your vet.
Chihuahua's are very small dogs, because of its small size, it does get cold much faster. This explains the Chihuahuas "burrowing" nature. They like to stay under soft warm covers.
overexcitable perhaps. im not a behavorist though so dont count on it :) if your seriously worried though talk to your vet.

I mean they are so small.....to them everything else is big and scarry
she probably needs to take a S.H.I.T
i think it's inherent to the breed.
