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!

Unfortunately boxers are very prone to skin tumours, and this looks like one on Mia's leg. The good news is that many are benign, and even the cancerous ones stand a good chance with early surgical removal. It is impossible to tell just by looking exactly what a lump is, so I would advise you to take her to your vet. They can have a good look at it and decide a course of action with you, be that monitoring it, testing it or removing it. Try not to worry too much as these things are normally fine, it is best to be cautious with boxers though.
