Okay, here is the skinny on Rio...if you care. :)
An entire day at the veterinary neurologist and a lot of money later...we ruled out pretty much everything else but 1. brain tumor and 2. the slim chance that the cause of Rio's seizures might be some type of infection in the brain.
We were "fortunate" (although that is kind of crazy to say) that Rio actually had a seizure on the way to the vet, so she was able to see first hand what was happening. We were also fortunate that he was somewhat mellow from the seizure, so they were able to poke and prod him, which is something he would never have allowed before. The people at the vet's office were very kind and spent a ton of time with Rio. They kept commenting on how sweet and great he was. That is kind of funny to us since his chart has "caution" all over it. :) Normally at the vet he stands the corner and growls at people. :) Anyway, the people there knew that any change in behavior (even for the better) is a sign of a problem, but they were nice to love on him anyway.
Unrelated to Rio's brain tumor, he also has a heart condition. Basically one of the valves in his heart is non-functioning. We have no idea how long it has been like this, but it is serious enough to eliminate his ability to undergo testing to rule in/out the brain tumor. All this to say, the vet believes that he has a tumor in the right frontal area of his brain, and the heart condition is serious, but unrelated.
The brain tumor is untreatable, so Rio is on some sort of doggie hospice. He takes medication five times a day (designed to slow the activity of the brain to slow down the seizures). He has quite the pill box. Our job is to keep him comfortable and allow for the best quality to life.
The good news is that Rio has been seizure free for a whole week!!! He is running around the back yard, barking at our neighbor's tractor, and otherwise terrorizing the neighborhood like usual. He is also very much enjoying his "pill delivery program", also known as cheese, sour cream, peanut butter, M&M's, and pretty much any kind of people food which was previously off limits.
Rio's medication also increases appetite, and he bangs (rather loudly) on his food bowl on average of 5 times a day. He has gained 3 pounds in 2 weeks, and is now sporting new love handles. The down side of this is that the medication has also makea him thirsty, and drinking water is his new favorite thing. He has to go to the bathroom all day (and night), and it is making me a little crazy.
We are feeling very positive about Rio's diagnosis and treatment plan. We know he won't be around forever (none of us will!), so we will do our best to take care of him while he is here. We are dedicated to that little pain-in-the-behind (Rio)!
Thanks for all of your thoughts...its is so crazy how much your pets become part of the family! We will keep you posted on Rio.
