Mange is a skin disorder caused by microscopic parasitic mites that burrow under a dog’s skin, causing irritation and discomfort. While once common globally, mange is now relatively rare in the UK, though it still occasionally occurs. Understanding mange is important because some types can spread to humans and other dogs, while others are not contagious but may affect a dog’s health.
This guide answers the most frequently asked questions about mange in dogs, helping UK dog owners recognise symptoms, seek timely treatment, and promote responsible care.
Mange refers to infection with one of two microscopic mites that live on or under a dog's skin:
Both types cause skin problems but differ greatly in transmission, symptoms, and treatment.
Sarcoptic mange can be passed to humans through close contact with infected dogs, causing itchy skin rashes. However, the mites cannot complete their lifecycle on humans and infections are usually self-limiting with no permanent infestation.
Demodectic mange is not contagious to people as it arises from mites native to the dog’s own skin flora.
Sarcoptic mange is very contagious and can spread from dog to dog through brief direct contact or contact with contaminated environments like bedding or grooming tools. Dogs diagnosed with sarcoptic mange require isolation until fully treated to prevent spread.
Demodectic mange is generally not contagious. Puppies may acquire mites from their mother shortly after birth, but these mites usually do not cause illness unless the puppy’s immune system is compromised.
Sarcoptic mange often causes intense itching, redness, inflammation, and hair loss, usually affecting the ears, elbows, chest, and abdomen initially. Untreated, skin becomes crusty and sore from constant scratching.
Demodectic mange may present with patchy hair loss and scaly skin, occasionally accompanied by bacterial skin infections. It can be localised or become widespread, especially in dogs with weakened immune systems. It sometimes affects paws predominantly, creating swelling and secondary infections.
A vet diagnosis is essential to confirm mange types through skin scrapings examined microscopically.
Diagnosis typically involves:
Yes, mange is treatable with veterinary care:
Prompt veterinary diagnosis and treatment are key to a successful outcome. Do not use human scabies treatments on dogs, as these can be harmful.
See your vet promptly if your dog shows:
Early veterinary intervention improves prognosis and reduces spread risk.
Aspect | Sarcoptic Mange | Demodectic Mange |
---|---|---|
Contagious | Highly contagious between dogs; transmissible to humans | Generally not contagious; mites from dog’s own skin |
Symptoms | Severe itching, red crusty skin, hair loss | Patchy hair loss, scaly skin, occasional infections |
Treatment | Antiparasitic drugs, steroids, antibiotics | Licensed dips/spot-ons, supportive care, antibiotics |
Prevention | Avoid contact, hygiene, isolation | Good immune health, vet care |
Understanding mange and quick action ensures your dog recovers well and protects your household. For more advice on dog health and finding healthy puppies, please consult reputable breeders and registered vets.
