self-made, thank you so very much. He's had another surgery yesterday. When the Vet saw him first she showed me a little piece of dissolvable suture in his subcutaneous tissue. She placed it there during last surgery in November of 2008 and it normally takes about 6 mths to completeley dissolve. Regarding the opening in his skin was right above the remnants of the sutures she suggested he might be rejecting the suture material. It's like his immune system has gone wild and is rejecting anything foreign placed in his body. So she removed whatever was left of those sutures. While performing the surgery she realized that the tissue looked somewhat abnormal where the sutures were placed, so she sent out a biopsy to the lab. It could be something as benign as reactive tissue(which I definitely hope so) or recurrent malignant growth. He might be also having some antibiotic resistant bacteria...So we'll know the lab results in a week. For now he's home, and seems to be recovering well, taking pain medication and antibiotics. Oh, I really have to fight him to squirt those things into his mouth. I'm keeping my fingers crossed that this time we've resolved the issue.
