Poor Snickett! Those spots on Snickett could be several things including allergies to fleas, something in the environment or food. Thyroid disease can also cause skin problems. I recommend for him to be examined by his veterinarian as they will likely prescribe treatment since it's all down his back. There are a couple things you can do at home and they can help but they are unlikely to address the underlying cause. You can try adding in an omega 3 fatty acid supplement for pets, this can help improve the skin health. You may also try changing his diet to something like Royal Canin or Nutro as they are aimed at skin health. Best of luck and please feel free to post any additional questions.
