Hi Iliana,

Without a specific diagnosis, it’s too difficult to suggest any specific treatments. There could be allergies but they could also be due to underlying infection with bacteria, yeast, or mange mites to name a few possibilities. Some treatments may actually make the hair loss or bumps worse. The hair will likely grow back once the underlying cause is identified and treated. A visit to your veterinarian is the next best step to get your pup back on track.

Best of luck,

Dr. Ryan Llera
