My puppy is 17 days old. His mother left him and he is the only one still alive from his litter. I am bottle feeding him. He has developed patches of his hair falling out. What do I need to do?

Hair loss can be caused by bacterial, parasitic or fungal infection, dietary or environmental allergies or sensitivities, immune system disorders, or a combination of the above. I recommend making an appointment to have Toby seen by your veterinarian to help determine the cause of the hair loss as soon as you can. The vet will likely want to look at a sample from the area (taken by a procedure known as a skin scraping) and examined under the microscope to determine what kind(s) of infection may be present and to figure out what medication is appropriate for treatment.
