My dog has a red belly but no itch. Is it a contact or food allergy?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Large (61lb +) | Female | spayed | 3 years and 7 months old | 73 lbs

Red on her abdomen but no raised bumps or patches. Doesn't seem to itch or bother her. No idea whether it's a contact allergy or something she is ingesting. Difficult to tell when it started because it was very, very mild and got worse gradually over the last week and a half or so. Have changed a number of things over the last month, both diet and environment, at vet's recommendation, so I'm trying to narrow down the cause. Is this contact allergy or food?

There is no way of knowing for sure from a picture but the location is more suggestive of something she is lying on. Food sensitivities can appear in many ways but itchy feet, ears and perineum are most common
