Thanks for using Petco Pet Education Center, formerly Petcoach! This could have been a small cyst, a small sting/bite (tick, other), or something like an area where a thorn or pricker was. Clean it out gently with some warm water or a little hydrogen peroxide. Keep an eye on it and if it becomes red, inflamed, has discharge, or you have any concerns, see the vet at your earliest convenience.
