Happy Boy Otis

Our dog Otis has 3 half-dollar sized rashes with flat, round red-patches and white centers – one on his rear armpit, one closer to the center of his groin and one on his neck. He also struggles with recurrent ear infections and has mild allergies.

We have now bathed him with an oatmeal based organic pet shampoo.

What is this? And how should we treat it?

Otis is a 10 month old Labradoodle.

Comments for 3 Half Dollar Sized, Flat Red Patches with White Center on Dog’s Groin, Rear Armpit and Neck

Hi Laura,

Since Otis is susceptible to skin problems, (recurrent ear infections and mild allergies), I suspect he has very sensitive skin which produces large reactions to minor injuries/stings/etc.

Considering the location of these ‘donut’ appearing rashes, I suspect they may be secondary to a tick bite.

You did not say how long these rashes have been present. If they persist longer than 3 weeks, and become worse, he should be seen by either a conventional veterinarian or preferably a holistic veterinarian.

Another resource for vets knowledgeable in homeopathy is AVH.org.

At this time, I suggest you clip the hair from each of the lesions and clean them daily with hydrogen peroxide. Continue the oatmeal shampoo one time per week for 3 weeks. Some homeopathic remedies that might be helpful, are Sepia, Sulphur or Arnica.

Use a 6C or 12C potency, one pellet by mouth of ONE of the above three times daily for one week.

Sepia–for circular lesions, for patient that seems tired out, wants to be in room with owners but will stay at the periphery facing away.

Sulphur–for RED lesions, for very itchy lesions, for patient that never seems clean even after bathing regularly.

Arnica–for bruised painful lesions, patient does not want to be touched on that area.

Take care,

by: Laura

Dr. Tillman:

Many thanks for your response. Otis, very happily, responded immediately to the first oatmeal bath and a very light application of aloe gel on the one, most recent, patch. We have also shifted him to a grain free, organic and raw food diet, which he is tolerating well. We appreciate your help and advice.

Very best, Laura and Otis

That looks just like ringworm.

Dear Anonymous,
On *human* skin, ringworm would look similar to this photo. But in dogs and cats, this is NOT what ringworm looks like. In fact the suggestions that I gave worked very well. The subscriber wrote,
” Otis, very happily, responded immediately to the first oatmeal bath and a very light application of aloe gel on the one, most recent, patch. We have also shifted him to a grain free, organic and raw food diet, which he is tolerating well.”

If the problem were ringworm, it would have become worse, not better. So, my suspicion that is was a superficial pyoderma, must have been correct.

Take care,
