Dear Tracy,
He is proably getting bitten by fleas and they are causing an allergy called miliary dermatitis. You can see it here:

You can treat it at home with cortaid but do not let him lick it off. Also use a monthly flea control product like revolution you can order from www.1800petmeds.com
Please let me know if you have any more questions. I will be happy to help.
Very sincerely,
Terri
