Hello, sorry to hear about Lenny. This could indeed be associated with his allergies and has not developed a local skin infection. This means that Lenny may require topical and/or oral antibiotics to treat the rash. Lenny should be evaluated by his veterinarian if this rash is not improving on its own or if its getting worse so that he can have medications. Hope this helps and best of luck.
