My 8yr old Anatolian Shepherd had a mass removal surgery done about a month ago. At the end of the second week of recovery he developed a large seroma (it was tested and not infected). The vet has since put 2 different drains in and although they work, the seroma re-develops after each time. He just had his most recent drain removed on Sunday and today (5 days later) I notice a small amount of liquid coming back. I really don’t want him to have to go into another surgery 🙁 will the seroma go away on its own? He doesn’t seem to be in any pain and the seroma is not warm to the touch, and it is much smaller this time around but I am worried it is going to just keep growing.
