Identify this spot please
Hi, new to the site. I rescued a 1 1/2 year old female gsd and love her to death. Awesome breed of dog. I recently noticed a small pee sized bump on her leg a da week later she licked the spot so much it's now exposed. It doesn't see to bother her a lot but I'm concerned what it might be. The bump is now smaller but it's exposed. I'll post a pic if anyone can identify this I'd appreciate it.
