Why does my dog have a painful rash on his inner thigh?

Updated On September 23rd, 2025

Pet's info: Dog | Miniature Pinscher | Male | neutered | 20 lbs

Hi I have no idea where my dog acquired this strange blustery rash on his inner thigh but I noticed it today and it is very painful for him. It seemingly appeared overnight and I’ve been applied dog anti septic spray and veterinarian grade steroid/anti fungal/antibacterial cream to the rash which seems to be helping, the middle photo is before application of the anti septic and triple action cream. What does this look like to you?

Hello. This is very typical of an allergic dermatitis reaction. Your treatment is appropriate so just continue until the skin is fully healed. Then, at the first sign of it coming back, start the cream again. You should also contact your veterinarian to see if the newer anti-allergy medications like Apoquel or Cytopoint would be appropriate to prevent these flare ups from happening. Thanks for contacting Petco Pet Education Center, formerly Petcoach.
