The two types — they're not the same
| Sarcoptic (scabies) | Demodectic | |
|---|---|---|
| Mite | Sarcoptes scabiei | Demodex |
| Itch | Intense, relentless | Mild — unless skin gets infected |
| Contagious? | Yes — to dogs and (temporarily) people | No |
| Typical spread | Ears, elbows, belly, then widespread | Face/legs (localised) or whole body (generalised) |
| Underlying cause | Direct contact with an infected animal | Weak/immature immune system |
What to look for
- Hair loss — patches starting on ears, face, elbows, or belly.
- Itching and scratching — often frantic with sarcoptic mange.
- Red, crusty, scabby skin; over time it thickens, darkens, and can smell if infected.
Mange looks like several other skin problems (allergies, fungal infection, fleas). That's why a vet confirms it with a skin scraping before treating — see also our guide to ticks and fleas, which cause similar scratching.
Treatment that actually works
- Modern isoxazoline products (the same class used against ticks/fleas) clear most mange safely and effectively.
- Medicated dips/shampoos help soothe and treat the skin alongside.
- Secondary infections (bacterial/yeast) are treated too — they cause much of the smell and crusting.
- Demodectic mange also means supporting the dog's overall health and immunity (nutrition, treating any underlying illness).
Never use motor oil, kerosene, or harsh home remedies. They burn the skin, can poison your dog, and don't cure mange — the mites live in the skin and need a proper anti-parasitic. Some drugs (like ivermectin) are also unsafe in Collies and herding breeds, which is another reason to let a vet prescribe.
If you've adopted or rescued a dog
Many rescued dogs in Pakistan arrive with mange — it's common, treatable, and not a reason to turn a dog away. With the right vet treatment and good nutrition, the coat grows back and the dog recovers fully. Keep a new dog separate from other pets until a vet confirms which type it is (sarcoptic is contagious), and wash bedding well.
A home-visit vet can do the skin scraping and start treatment without a clinic trip — post your request and budget on MatchVet and verified vets respond.
Frequently asked questions
What are the signs of mange in dogs?
Hair loss (often starting on the ears, face, elbows, or belly), intense itching and scratching, red or crusty skin, scabs, and — over time — thickened, darkened, sometimes smelly skin. Sarcoptic mange is famously itchy; demodectic mange can cause bald patches with less itch unless it gets infected.
Is mange contagious to humans and other pets?
It depends on the type. Sarcoptic mange (scabies) is very contagious — it spreads to other dogs and can cause a temporary itchy rash in people. Demodectic mange is not contagious; it flares when a dog's immune system is weak. A vet tells them apart with a simple skin scraping.
How is mange treated?
Modern isoxazoline products (the same class used for ticks and fleas) treat mange very effectively, often alongside medicated dips or shampoos and treatment for any secondary skin infection. Some older treatments like ivermectin must never be used in Collies and related herding breeds due to a genetic sensitivity. A vet chooses the right, safe option for your dog.
Can I treat mange at home with oil or kerosene?
No — please don't. Used motor oil, kerosene, and harsh 'desi' remedies are common in Pakistan but they burn the skin, can poison the dog, and don't cure mange. Mange needs a correct diagnosis (which mite) and a proper anti-parasitic. The good news is real treatment is affordable and works.
Why is mange so common in Pakistan?
It spreads easily among street and rescued dogs and in crowded or unhygienic conditions, and weakened or malnourished dogs are more prone to it. Many adopted dogs arrive with mange — with proper vet treatment and nutrition, most recover fully.
