  • Fear. Some Chihuahuas shake from fear, especially is they have been subjected to any form of abuse. Firm but kind handling can go some way towards helping him overcome fearful emotions.
  • Cold. Shaking raises the metabolic rate and warms a little dog up. These pooches don’t have much in the way of body heat to keep them warm in winter and they tend to lose what little body heat they do have rather quickly. Sometimes just warming them up will stop the shaking.
