Hi, thanks for using Petco Pet Education Center, formerly Petcoach. It's hard to say with out seeing a picture or without knowing more information. If he was neutered recently or in the last few weeks and the blister is by the old incision it could be a suture reaction. There are many reasons for red skin bumps. You can gently warm compress the bump twice daily. If you can post a picture it may help. Otherwise get it checked by your Vet if it doesn't get better
