My dog has itchy rash spots on his belly. Is it just allergies?

Updated On September 23rd, 2025

Pet's info: Dog | Beagle | Male | neutered | 12 years and 8 months old | 35 lbs

Charlie recently developed 3 separate rash spots on his belly, and I’m wondering if there’s reason to be concerned or if it’s just allergies? They have been itchy, but he can sleep through the night without waking up to itch them. He was previously on sensitive skin and stomach food from prior history of allergies which helped significantly. Within the last year he had to switch to bladder diet food due to oxalate stones. No obvious signs of infection or pain. One has small raised circle.

I am sorry to hear about Charlie! This could be a mild allergy or skin irritation if it is just a small area. You can try starting a[ fatty acid supplement](https://www.petco.com/shop/en/petcostore/product/vetri-science-laboratories-omega-3-6-9-dog-and-cat-gel-caps) which can help decrease inflammation and itching in the skin. Ask your vet if they feel an antihistamine, such as Benadryl or Zyrtec, is safe for Charlie given his health history. You can also try a topical product such as Duoxo Calm spray or gel on the area. If more lesions develop or these aren't resolving then a trip to the vet is recommended.
