Overgrooming – dogs excessively groom to address stress or pain.Parasites like fleas – these lead to intense itching and chewing.Poor diet, which can lead to loss of vibrancy and hair loss in dogs.Allergic reactions – to food or environmental substances.Inflammation that can damage the hair follicles.Endocrine system abnormalities like Cushing’s or hypothyroidism.Autoimmune disease where hair follicles are destroyed by the immune system.Trauma such as a burn or repeated action like scratching or chewing.And that’s when you may want to ask your vet to examine your dog, to make sure he doesn’t have more serious health issues.Īny time there’s a disruption in the growth of the hair follicles it can lead to hair loss.
