Dog has fluid in belly, weak pee, slow. Vet suggests surgery. Why?

Updated On September 23rd, 2025

Pet's info: Dog | Siberian Husky | Male | neutered | 8 years and 8 months old

My dog was bloated so I thought he overate, then a day or 2 later still bloated, his peeing stream was weaker , walking slower. Vet ran tests(pictured)& they can’t tell me what’s wrong but that there is fluid in in abdomen with protein trances. They want to do exploratory surgery & sample his liver & small intestine. i mentioned the peeing multiple times to the vet but he didn’t seem to consider it much, which I think is a little wierd since he usually peed with ease before. Any suggestions?

Without a hands-on exam I really cannot say much about the peeing. It is quite possible that the excess fluid in the abdomen (often a sign of liver disease, cushing's disease, heart disease and tumors) could be pressing on the bladder and so hinder urination. An exploratory surgery will lay open the abdominal content and your vet will be able to immediately tell what your dog's problem is and possibly why he has ascites (fluid in the abdomen). Without seeing the results of the tests I also cannot tell you what your veterinarian may suspect, however since he wants to do an exploratry laparotomy he is likely suspecting a problem with the liver. The bloating is actually an expansion of the abdomen caused by the fluid. I am sorry about your dog being so sick. I would say an exploratory laparotomy is likely the best way to find out what is wrong with your dog.
