The two types of mange require completely different approaches: sarcoptic mange (scabies) is highly contagious to other pets and even humans, causing intense itching, and demodectic mange usually appears when a dog's immune system is compromised or in puppies whose immune systems are still developing, and is not typically contagious. A vet must perform a skin scraping under a microscope to tell them apart — guessing based on symptoms alone leads to ineffective treatment. Both types are treatable, but demodectic mange in adult dogs sometimes signals an underlying health issue worth investigating, since it shouldn't normally appear in a dog with a healthy immune system.
Mange is a skin disease caused by mites. It can cause serious discomfort, hair loss, and skin damage if left untreated — persistent discomfort can also manifest as behavioral changes resembling fear or anxiety.
Types of Mange
Sarcoptic mange is highly contagious and causes severe itching. Demodectic mange usually appears when the immune system is weakened.
Recognizing Symptoms
Watch for scratching, hair loss, red skin, crusts, sores, odor, and irritated patches.
Diagnosis Process
Veterinarians diagnose mange using skin scrapings and microscopic examination.
Treatment Approaches
Treatment may include prescription antiparasitic medicine, medicated baths, antibiotics for infections, and cleaning the environment.
Home Care and Prevention
Wash bedding, clean grooming tools, maintain good nutrition, and keep up with regular vet care.
