A bit of bad news. Not a bit really - more like a mountain. Our little Truffles has idiopathic encephalitis. Sorry for the medical speak, but we have lost three dogs in five years and have likely spent somewhere in the neighborhood of forty thousand dollars on vet bills in that time, so we have become accustomed to vet lingo. We knew something was wrong when she had what appeared to be a petit mal seizure and began circling left whenever she attempted to walk.
In layman's terms, there is an area of her brain that is swollen. We have not identified the cause, but it's more important that we know what we are dealing with. It took a few thousand dollars and a battery of tests to narrow it down: Now we are going through a painful process of elimination as it pertains to treatment. Since the cause is not known, the usual course of treatment does not apply. She has gone through four rounds of meds and we're not there yet.
So we treat, and wait, and hope. The good news is that she is holding steady; her condition has not worsened. She is a tough little cookie, and that huge heart of hers is brimming with love. Please send good wishes her way - throw her a bone in your prayers. She'll love you for it, as will we.
