My dog has sudden red spots on her belly and armpit. What's wrong?

Updated On September 23rd, 2025

My dog has perfectly circular or oval shaped, bright red spots in her groin area, and one in her armpit. They appeared over night it seems. They do not itch, they are not raised. She does have allergies that show near her tail.

I would recommend going to the vet. Sometimes this can occur with insect bites, but it could also happen with autoimmune disease or bleeding disorders. The vet will do a thorough examination, and based on their findings and the medical history, may recommend blood work or other testing.
