Is my dog's itchy, red skin with pus an infection or allergy?

Question

My shepard has very itchy, red, inflammed lesions at the base of his tail in multiple spots. It is also on the tip of his penis. I seemed to be finding new spots that start off at very red & raised which then turn into lesions with greenish scabs and puss.

Hi, and thanks for your question. This could be due to an allergy, although it could also be infection or mites. First of all, in order to rule out skin parasites, you will need to treat with a high quality flea treatment, then ask the vet to perform a skin scrape - this might reveal an infection or a mite infestation. If all of those came back negative, the next step is to treat the allergy symptomatically and try to discover the cause of the allergy. Three main type of allergies are usually affecting pets: food allergies, flea and parasite related ones and environmental type (allergens coming from trees, pollens, dust etc etc). Some medications can be given by the vet in order to repair any possible skin lesions (like steroids and antibiotics).
