Puppy with Ringworm Like Lesion

Yesterday after hiking I noticed my dog had a bright red blood blister like lesion on his tummy, it was raised and had a small black spot on it, but the overall texture was smooth and it wasn’t bothering him. We first checked to see if it was a tick, but it wasn’t. Now it has been 32ish hours and it has healed to look similarly to ringworm, though it doesn’t feel scaly and it’s not bothering him. Is this how ringworm usually manifests in dogs? It’s possible (and likely) he scraped his belly as he went over some rocks. We’re not sure if we need to go in to the vet or not. The top picture is about an hour after our hike, the second photo is it healing after 32ish hours.

Hello - First of all, we would recommend that if ever you suspect Ringworm, you wash your hands very well and be aware that ringworm is infectious, so be particularly careful and please keep your dog away and yourself away from children, pregnant women or anyone else who may be immunocompromised.   IN the case of this picture, we think that you should call your vet and ask them to triage the case to establish how soon they want your dog to be seen or what to do in the meantime.  Dogs don't get the same target lesions that we see in people with Lymes disease, but there are other strong differentials:  for example, reactions to fly bites can look like this.

as can reactions to some foods and drugs.

In answer to your questions, this is not how Ringworm usually presents.  Autoimmune diseases and Erythema Multiforme may also be on the list, but are perhaps more unusual.  Your vet should triage - perhaps you can show them a picture - and take it from there.

Hi, I have the same issue with my 5 month Maltipoo, please help. What was the issue?
