my dog got his umbilical hernia repaired about a month I noticed that it is taking a long time to heal there isis still a spot that seems to be still oozy and today I felt somthing pointy coming out of hiS Incision. I am freaking out! My poor baby I cannot get a good picture of it but it looks like clear fishing line. I had no idea it was sticking out until today. Does anyone know what this is ?
