He needs to see the vet so they can look at his skin, make sure there is nothing going on in the area, probably have skin testing (like cytology) done, and run blood work.
Sometimes things become less of an issue for dogs when they are away from home (vet, daycare), sine there are more important things to think about for them. But there could still be a problem.
