I did find out that the vet she goes to is into neurology. Here is his info.
Wabash Valley Animal Hospital Terre Haute, IN, 47802 - YELLOWPAGES.COM
Mom has been using him for years. He saved her other Yorkie, who was in horrible condition from the pet shop she got him from. He had pneumonia and weighed less than a pound. He needs eye drops everyday. (Pet shop was closed by health department) Mom also has a dog who has seizures that is on meds and goes to the same vet. He even prolonged the life of my mom west highland, giving her a few more years than she would have had. Hopefully he can save little Pebbles. My mom is just sick over this. If you pray, please pray for her and my mom. Thanks so much!
