It is always very sad when you see your dog lose its hair. Most times when your dog loses its hair, there is an underlying infestation or infection which is making your dog miserable. Unfortunately, some of these issues can be very difficult to diagnose, and can take months to isolate.
I have spent many hours researching the health issues that cause hair loss in dogs because of the health of my own dog. I compiled a list conditions that cause hair loss, how to diagnose them, and where possible, how to treat them. I hope you find these articles useful.
