That looks like it could be a mild skin infection, irritation from a leash or harness or even the result of an insect bite. If you use a harness I'd suggest not using it for a few days to allow the skin to heal. You can apply a small amount of triple antibiotic ointment to the area. If the area is not healing in a few days you may want to bring Champ to your veterinarian. Your veterinarian can take samples from the area to make sure it isn't a more significant infection or other skin issue. Thanks for using Petco Pet Education Center, formerly Petcoach and I hope Champ's skin heals quickly!
