Unfortunately, the photo is very fuzzy and of poor contrast so I am unable to really make much of an assessment out of it. Best guess, it looks like it could have been a self-inflicted wound called a lick granuloma, but this would need to be confirmed by a vet to be certain. If the lesion is getting smaller and is non-painful to the touch, it may not be very concerning since it very well might be resolving on its own. If it is in fact a lick granuloma, the best thing you can do for it is clean it with dilute betadine or chlorhexidine solution, apply some triple antibiotic ointment to it daily, and make sure Eddie has a cone on so he can't lick the area to make it worse. However, the reality is, if you really want to know more information on the origin / cause of the lesion, you are going to need to have a professional take a look at that in person. Hope this makes sense.
