Also Yorkies are know for having Atlantoaxial Instability. This is a congenital defect in the neck.. SO please ask your vet about this too. He will need to do xrays(digital xrays) to be sure.. And some vets do not hear of this very often but believe me it is out there.. My Babybear is one that has had it, and we have a few others on here that have Atlantoaxial Instability(AAI for short) you will see many of us using the AAI/AAS instead of the Atlantoaxial Instability.. If you would like to read more on this defect you can go to Babybear's webpage on Dogster and read his diary the information is in there and in his story on the right handside of his page..
