Do dogs have to go to the vet to have their ascites pumped?

It is advisable to go to a regular hospital for abdominal fluid extraction. Also do the relevant tests to see the nature and source of the ascites. Only with a rigorous diagnosis can you make a better plan to treat the disease. The pumping of ascites at home, if not properly disinfected, can easily lead to abdominal infection and result in peritonitis.
