Wow. There are a few reasons why a dog would do this. This is not a Chihuahua Thing, this is either an emotional issue, or a neurological one. More than likely this is not a health issue. Chihuahua's can actually stress themselves out over family issues, so if the puppy has no neurological issues, stress/emotions is the cause. I can fix this, but you will have to contact me through NextDayPets. Our screen name is Jarbeth.
