my guy has gotten bitten in several areas on his belly. he keeps biting on them and is making his tummy very irritated. i used peroxide on the bites (whatever kind of a insect, it had a field day on my guy. he must have about 8 - 10 bites) and a cortisone spray to relieve the itch. is there anything else you can recommend that i can do for him? thanks for your answers.
