Thanks for the replies!
Villette- one of the many vets I brought him to thought it was his collar so h e hasn't worn one since ( i know that's bad... but I don't want him itching) but the rash is back. He gets an oatmeal bath once a week with medicated shampoo... still a rash! He doesn't wear clothes very often at all. Maybe once a month for 20 minutes. Still a rash! I'm running out of options and I might need to do the allergy testing.
