Our 11 year old Lab became sick between Xmas and New Year. After nearly 3 weeks on tablets for gastritis he wasn't much better. Tests then showed that the retained testicle he had (I know this should have been sorted out when he was younger, but we only took ownership of him 4 years ago) had become a tumour and was blocking his digestive system. He had the operation just over a fortnight ago and was doing well. Then he got a slight cough. In hindsight I think I should have seen how that panned out, but I rushed him back to the vet, who wasn't our normal one. He swapped the meds our dog was on from Zitac (aka cimetidine/tagamet) and Tramadol (which he was getting waned off) and put him on Steroids and Antibiotics. Next day our dog was violently ill. I thought he was dying tbh. Back to the vets (another one) and he was put back on just Zitac along with some Pro-Kolin paste, together with a bland diet. Since then, good days and bad days. Yesterday he threw up a couple of times, just yellow bile. This morning he threw up some clear liquid after drinking water (he's drinking huge amounts). He hiccups sometimes and his breathe has an acid smell, so he's obviously having some kind of acid reflux problem. His stool are very loose. I don't want to keep taking him back to the vets. He's traumatised. I could barely get him out of the car last visit. So I need advice how to proceed. He's gone from 35kg (He's a big Lab) to 29kg, and I'm feeding it difficult to finding the balance of getting him to eat enough so he has energy and doesn't waste away, but not too much so he's instantly sick. At the moment he's on chicken and rice mixed with dog food the vet suggested called Specific Digestive Support, but he's mainly just picking out the chicken. It's been 5 weeks since he first became ill, and with the set backs it's becoming very stressful. I'm not sure if he will ever get back to normal, but I would like advice on how to manage his condition and give him a decent quality of life.
