My dog has sores, blisters, and hair loss. Could it be pyoderma?
Skin lesions can be caused by bacterial, parasitic or fungal infection, dietary or environmental allergies or sensitivities, immune system disorders, or a combination of the above. Logan may indeed have pyoderma, but further testing is needed to help determine if this is the case. Make note of if there is a seasonal recurrence of the lesions, as environmental allergies often cause recurring irritation. I recommend making an appointment to have Logan seen by your veterinarian to help determine the cause of the red areas you’ve noticed and to make sure they are treated appropriately. The vet may want to look at a sample from the area under the microscope to determine if there is an infection and to figure out what medication is appropriate for treatment.
