Anyone know a good Podiatrist?

Noticed that something didn't look right with Samson's foot about 4 days ago and today he was finally sunning that foot and I got a pic. Web feet dont heal themselves so this is definitely alarming. Called Bob the Swan Guy and he said looks like we might have an aggressive fish in the pond. Ughh, so we will keep and eye out. Looks like Delilah feet are both fine, as is Samon's other foot.
