another trip to the vet

my poor sweet boy.......foster had to make a quick trip to the vet yesterday.
dave and i noticed yesterday morning that foster had a large swollen and bloody area around where his stitches had been for his neutering 6 weeks ago. vet's diagnosis: allergic reaction to the stitches which dissolved in that spot. rare but happens. everything is still stitched up and secure but now he's having a bit of an immune reaction to perhaps whatever coats the stitches.
meanwhile he's taking amoxicilin and getting a warm compress on the spot 2X a day. he will head back to the vet in one week. :((
seriously, is there anything this dog doesn't get?! he's worse than my mother!!
