[Thatcher]

Hi there,
I have a two year old yorkshire terrier, Thatcher. He is 7 1/2 lbs.

Every 2-3 months he gets violently ill. He usually gives no warning and just starts to throw up. It usually occurs every half hour and then eventually diarrhea begins also. He has had at least 5 overnight visits to the vet hospital costing anywhere from $950 - $1600 per trip. He is so dehydrated by the time he gets to the vet that he always goes on IV. He is not allowed human food but occassionally grabs something. Usually this doesn't bother him.
He has also had pure blood vomitted up too during these violent illnesses. There have been no signs of poison or ingestion of a toy or other object.

I've seen a specialist for ultrasound but he has no clue. They have ruled out a few deseases but nothing solid yet.

Any thoughts or advice would be greatly appreciated.

Kind regards,
Thatcher's Mom
