Thank you for submitting your question regarding Piper. I recommend that she sees a veterinarian. Skin disease can be frustrating as many diseases can appear similar. Common cause of hair loss include mites, ringworm and allergies. An allergy can be to something in her diet, environment or even fleas. The veterinarian will examine her and ask questions about her lifestyle. Skin testing may be recommended. Based on these results, treatment can be started. I hope this information helps!
