13 year old Yellow Lab won't eat or drink
I have a 13 year old Yellow Lab that recently had surgery to remove his spleen which had grown a mass on it. It did not appear to be cancer. His recovery seemed to go well the first few days but he slowly stopped eating. At first we thought it was that he wouldn't eat his dry food because the vet was feeding him wet food, so we caved, and tried wet food but now he won't eat that either. He also stopped drinking and began to have very loose bloody stools. We took him back to the Vet and he is now on an IV with antibiotics. We were hoping he was perhaps having a bad reaction to the medicine he was on but he has been off all meds for 1 week and still no appetite after 24 hours of IV. The Vet wants to do more x-rays and blood work that it seems like we just did a week ago. I don't know where to go from here. I don't necessarily feel like I'm being milked, but aren't there other things to try before another $500 in tests? Maybe this is more of a rant that a question but I am at a loss.
