What do I have?

I have been sick since I got kennel cough. This week I have been acting so strange. I have acted as if I am chewing gum and my head quivers. Friday, mommy pet my ears and I fell on my side and kicked. Sat. I was so restless and could not find a place to be. I had something on my mane so mommy told me to sit. She came over and wiped the front of my mane and my front feet went from under me and I was rocking my head. Thankfully, we had a vet visit scheduled already. The vet had mommy put me on the floor and he just watched me. He said it looked as if I was about to go into a siezure. I was put on anti-siezure med. and he took alot of blood. He called mommy this morning and said my thyroid tested low. He is going to do another test on the blood and see if my thyroid was low before I acted strange. He said siezures can cause a low thyroid but, a low thyroid can cause these type of symptoms. I will let you know how I turn out tomorrow when we get the report. Mommy told the vet right out that she was so worried and scared for me. Keep your paws crossed. Thanks!
