Hi, thanks for using Petco Pet Education Center, formerly Petcoach! A lot if skin bumps can look the same. But for a young dog and the location of it being on a leg it is likely a benign growth called a histiocytoma. They usually spontaneously regress in a few months. The other possibility is a Mast cell tumor, which can be common in Boxers. If the bump grows larger or doesn't go away in 2-3 months I would have your Vet examine it and consider aspirating it to see what it could be. It is never wrong to get it looked at sooner either! I hope this helps!
