Mange Treatment Checklist
Mange in Dogs: Types, Symptoms, and What to Do
Mange is a skin disease caused by parasitic mites that burrow into or live on a dog’s skin. It causes hair loss, itching, and skin irritation that ranges from mild to severe. Two distinct types exist — sarcoptic and demodectic — and they differ in contagiousness, cause, and treatment. Always have your vet diagnose and treat mange; this article is for educational purposes only.
| Feature | Sarcoptic (Scabies) | Demodectic |
|---|---|---|
| Mite | Sarcoptes scabiei | Demodex canis |
| Contagious? | Yes (dogs & humans) | No |
| Primary Symptom | Intense itching | Hair loss, scaling |
| Most Common In | Dogs exposed to strays | Puppies, immunosuppressed dogs |
| Typical Locations | Ears, elbows, belly | Face, paws, or generalized |
Sarcoptic Mange (Scabies)
Sarcoptic mange is caused by a microscopic mite that burrows under the skin. The intense itch is an allergic reaction to the mites’ presence. It spreads through direct contact and can temporarily affect humans in the household. Dogs with sarcoptic mange scratch relentlessly, often leading to secondary bacterial infections from open sores. Isolation from other pets and prompt veterinary treatment are essential.
Demodectic Mange
Demodex mites are a normal part of canine skin flora. Demodectic mange develops when a dog’s immune system fails to keep the mite population in check — most commonly in puppies, senior dogs, or those with underlying illness. Localized forms (small patches) often resolve on their own. Generalized demodectic mange (widespread hair loss, skin thickening) requires veterinary treatment and investigation for an underlying immune cause.
When to Call Your Vet
Call your vet immediately if your dog has: significant hair loss; skin that is red, crusted, or oozing; intense, relentless scratching; a foul odor from the skin. Do not attempt to treat mange at home with over-the-counter remedies — many are ineffective, and some can be harmful.
Frequently Asked Questions
What is the difference between sarcoptic and demodectic mange?
Sarcoptic mange (scabies) is caused by Sarcoptes scabiei mites, is highly contagious to other dogs and humans, and causes intense itching. Demodectic mange is caused by Demodex mites that naturally live on dogs’ skin; it is not contagious and is associated with immune system issues rather than contagion.
Can my dog’s mange spread to me?
Sarcoptic mange can temporarily spread to humans, causing a red, itchy rash. The mites cannot complete their life cycle on human skin, so the condition self-resolves once the dog is treated. Demodectic mange cannot spread to humans.
How is mange treated in dogs?
Treatment depends on the type of mange and must be directed by a veterinarian. Options include antiparasitic medications (topical, oral, or injectable), medicated shampoos, and in some cases antibiotics for secondary skin infections. Do not self-treat.
