Thank you all for your thoughts & hugs. Jack is at the specialist right now. I had to fashion a muzzle to get him loaded up into the car. My dog has never growled at me, so I knew he had to be VERY uncomfortable. I packed a pillow case from one of our pillows to put in his kennel to help him while he waited for the vet. We are hoping that he is just going to have to be confined for a while longer and then he'll be better. When I find out more I will post it.
