Poor Chalie! Black discoloration in the skin can occur as a result of chronic inflammation (from infection, fleas, allergies, etc.) or due to endocrine/metabolic conditions (such as hypothyroidism or Cushing's disease). Make sure that Chalie is receiving a high quality flea preventative (such as Nexgard, Bravecto or K9 Advantix II) regularly. You can also try bathing him in a gentle oatmeal based dog shampoo, because this can be soothing on the skin. I also recommend taking Chalie to his vet for further evaluation of his skin to determine if there are more chronic conditions that should be addressed. I hope that all goes well!
