We're extremely touched by everyone's comments and suggestions and help!
Yoda is now back home! YAY! He has been more active today, they took him for a little walk around the vet clinic and he got to sniff around and mark some territory. We brought him home and he was able to eat more food today. He has been feeling like walking around the house more and was even able to walk up his three stairs to lay in his favorite position, which is Daddy's lap on the couch. He's also been able to bark and growl when he feels someone may be intruding upon his domain.
Yoda is due back at the vet in a week or two to do bloodwork to see if there are any changes. We're going to be putting him on a strict diet, most likely rice with chicken breast, along with the vet recommended Royal Canin Digestive Low Fat LF. He is still supposed to get famotidine (Pepcid AC) 2.5mg by mouth twice daily for a while.
Thanks again to everyone that has supported us and given us support and hope through this whole ordeal. We hope Yoda continues to get stronger and stronger each day. I hope every member that posts in this Sick & Emergency forum gets support and help they need for their troubled Yorkies.
