Gobo

This past weekend my little baby, Gobo, was sick. he seemed constipated and eventually decided he really didn't want to eat. When we did get him to eat, he'd eventually just throw everything back up. So yesterday he and I went to see the vet. I was hoping they'd find a blockage or something that could easily be "fixed" though deep down, I suspected something more. We spent 3 hours there yesterday while they ran blood tests and tried to collect a urine sample to test that. Unfortunately, we got our answer. My poor little boy is dealing with kidney failure. He was born with several obvious birth defects and we always kind of wondered if there might not be some internal issues he'd eventually have to deal with as well. We never expected this, at least not his soon. He is 4.5 years old, barely out of puppyhood and kidney failure this severe and sudden is very uncommon for one so young. Because things have already progressed as far as they have, and as sudden as this all was (he really didn't seem at all sick or have any sudden changes in habits until this past weekend, though he has lost nearly 3 pounds since last year's visit..) there really isn't much we can do for him except wait and try to keep him comfortable. He has managed to keep some food down since yesterday, so that is good.
At this point we are just hoping that he can do ok and keep going for another 2 weeks at least. Tom would really like the chance to get to say good bye. The last 2 dogs we had that passed, both went while he was away and very suddenly. This time we at least have warning and can prepare, though that just means my grief has already started to set in. They figure he probably has a few weeks, maybe even a few months. Any treatment we could do would be very expensive and, even then, maybe only give him an extra month or two, if it did anything at all.
I really do wish there were more we cold do for him, but at this point, there just isn't. The numbers from his tests were insanely high, several were well beyond the parameters, they were literally off the charts.
I'm loosing my baby and it's tearing me to pieces..
