Hello and thank you for your question about Gizmo! Although I can't say for sure what the problem is with Gizmo without examining him first and running a few skin tests, I can provide a few possibilities. Loosing fur can have many causes: a mite infection, bacterial or fungal infection or it could signal a endocrine disorder such as hypothyroidism or cushing's disease. The brown spots may signal a fungal or yeast infection. You veterinarian will run a few skin tests to determine the cause and provide the appropriate treatment based on diagnosis. I hope this helps and best wishes to you and Gizmo!
