I'm desperate for any thoughts. Sorry it's so long but I don't want to miss any details. Buster is an 8 1/2 year old neutered male. It started the beginning of May, Labor Day actually. He started to refuse his regular meals but would still eat canned food. So we played the waiting game with his food, we thought that maybe he was just being stubborn. 4 Days of that was about all I could take. Took him to the vet and they ran blood work, which came back fine and prescribed an antibiotic for his gums (he's got gingival hyperplasia). They said to go ahead and just keep him on canned food. Well, that night he started to refuse canned food as well. So we stared him on rice and chicken. He ate a bit at two different meals and stopped that. Long story short he had only been eating maybe an eighth of a cup of whatever he will eat and many hours later (6+) he'll vomit it up undigested. Of course he has diahrea as well because he isn't digesting anything. He went back to the vet on this past Monday. They did a few xrays and found absolutely nothing on those. Sent us home with anti nausea and stomach ulcer medicine. He has gone from 94lbs. and is now down to 62lbs in a matter of 3-4weeks. I was doing some research yesterday and came across the possibility of Addisons disease. Called the vet and to find out their thoughts on this and they are going to recheck his blood for electolyte levels. But until I hear back this afternoon I'm just a wreck. It is so heartbreaking to look at him and still see him so mentally healthy and happy to be loved and not be able to help him. Please, if you have any thoughts on what else could possibly be going on I would love to hear them.
