Weird place to post

First off this is a weird place to post this but idk how to google this. A few weeks ago, my dog got cut and she had to have staples. She's since had the staples removed and all that stuff for a few weeks. But there's this spot (picture below) that won't heal. It's not on the scar, the scar is below. Whatever it is, it's from the actual staples. Anyone have any idea what this is? Or has anyone else had to get their dog stitches and had this? It's not causin her any pain (I was poking at it and inspecting it and she slept through it)
