Our darling yorkshire terrier's health continued to decline very quickly. It appeared that Kelsey had a fast-growing brain tumor. Only 3 weeks after her first seizure, I made the difficult decision to have Kelsey put to sleep. The date of her death is September 10, 2008, nine days shy of her 13th birthday. Our home is painfully empty, so our plan is to wait a couple of months, then consider getting another dog.
