Mange treatment costs $200-$600 - caused by microscopic mites that burrow into the skin or live in hair follicles. There are two main types: demodectic mange (from Demodex mites, not contagious) and sarcoptic mange (from Sarcoptes mites, highly contagious to other dogs and humans). Both cause intense itching, hair loss, and skin infections. Treatment takes 4-8 weeks.

What Causes Mange
Demodectic (Demodex) mites live in hair follicles - normally present on all dogs. They flare when immunity weakens, typically in puppies or immunocompromised dogs. Sarcoptic (Sarcoptes) mites burrow into the skin, causing intense itching, and are highly contagious. Two types: demodectic and sarcoptic

Symptoms

What to Watch For
Demodectic: patchy hair loss on face and legs, red scaly skin, minimal itching. Sarcoptic: intense itching, constant scratching, crusty red skin on ear tips, elbows, belly. Secondary infections common in both types. Sarcoptic mange causes intense, constant itching

Diagnosis

$50-$150
A skin scraping ($50-$100) lets the vet examine a sample under a microscope to identify mites. Demodex deep in the follicles requires deeper scraping. Sarcoptic mites are harder to find, so multiple scrapings are needed. A negative result doesn't rule out sarcoptic. Trial treatment may start based on symptoms. Average $50-$150

Treatment

$200-$600
Isoxazoline medications (NexGard, Bravecto, Simparica) - the main treatment for both types, $30-$80/month. Ivermectin ($20-$50/treatment) is an older option. Antibiotics for secondary infections ($50-$150). Medicated baths ($20-$50 each). Treatment continues until skin scrapings clear. Average $200-$600

Total Cost

$250-$750
Diagnosis, 4-8 weeks of treatment, and follow-up skin scrapings. Generalized demodectic mange costs more - $500-$1,000+.

Breed Risk

Shar-Peis, Bulldogs
Shar-Peis, Bulldogs, American Pit Bull Terriers, and Staffordshire Bull Terriers are most prone to demodectic mange.

Recovery

4-8 Weeks
Treatment takes at least 4-8 weeks. Generalized demodectic mange can take 3-6 months. Two negative scrapings confirm cure.

Prevention
Monthly isoxazoline preventatives protect against sarcoptic mange. Don't breed dogs that had generalized demodex. A healthy immune system is key.

Insurance Traps

Mange treatment is covered by most policies - but there are catches.

Mange Coverage Basics

Waiting period
Most policies cover mange diagnosis and treatment as standard illness. 14-day waiting period applies. Both demodectic and sarcoptic treatment - medications, medicated baths, follow-up scrapings - typically covered.

The Puppy Demodex Trap

Pre-existing
Demodectic mange often appears in puppies under 18 months. If diagnosed before enrollment, future skin and mange claims get denied as pre-existing. Even resolved localized puppy demodex leaves a permanent record.

Treatment Cost vs Coverage

Chronic condition
Mange costs $250-$750. With a $500 deductible, simple cases may not exceed it. Insurance is worth more for generalized demodectic ($500-$1,000+) and chronic cases.

Parasitic vs Preventive

Chronic condition
Mange treatment is covered as illness care. But the isoxazoline meds used for treatment are the same as flea/tick prevention - only treatment doses are covered, not ongoing preventive use.

Common Questions

Real answers about costs, treatment, and insurance coverage.

What does mange look like on a dog?
Demodectic: patchy hair loss on face and legs, red scaly skin, minimal itching. Sarcoptic: intense itching, crusty red skin on ears, elbows, belly. Severe cases: thickened, darkened skin. Secondary infections cause oozy, foul-smelling patches.
How much does mange treatment cost?
Total: $250-$750 - diagnosis ($50-$150), medication ($100-$400 over 4-8 weeks), follow-up scrapings ($50-$100). Generalized demodectic: $500-$1,000+. Isoxazolines (NexGard, Bravecto): $30-$80/month. Antibiotics: $50-$150.
Is mange contagious to humans?
Sarcoptic mange can pass to humans, causing itchy red bumps on arms, chest, and waist. It clears up on its own: canine mites can't complete their life cycle on human skin, and it resolves within weeks once your dog is treated. Demodectic is NOT contagious to humans or dogs.
What's the difference between demodectic and sarcoptic mange?
Demodectic (Demodex): mites normally live in follicles and flare when immunity is weak - not contagious. Sarcoptic (Sarcoptes): mites burrow into skin, highly contagious. The key difference: sarcoptic causes intense itching; demodectic causes little to no itching.
Can mange go away on its own?
Localized demodectic in puppies often resolves as immunity matures - ~90% clear untreated. Generalized demodectic and sarcoptic do NOT resolve on their own. Untreated sarcoptic causes severe suffering and serious secondary infections. Always get diagnosis first.
How do dogs get sarcoptic mange?
Direct contact with infected dogs, wildlife (foxes, coyotes), or contaminated bedding, collars, grooming tools - mites survive several days off host. Dog parks, shelters, and kennels are common sources. Mites are microscopic and invisible.
What breeds are prone to demodectic mange?
Shar-Peis, English Bulldogs, American Pit Bull Terriers, Staffordshire Bull Terriers, American Staffordshire Terriers, Boston Terriers. Genetic link is strong - don't breed dogs with generalized demodex. Any breed can be affected, but these have an inherited immune deficiency.
Does pet insurance cover mange treatment?
Most policies cover demodectic and sarcoptic mange - 14-day waiting period applies. Prior mange or skin issues trigger pre-existing denial. Monthly flea/tick preventatives (isoxazolines) classified as preventive care, not covered.

Then came the shock. August 2026, I'm sitting on a bench outside a veterinary clinic in Brno. After his first epileptic seizure. Alf, healthy until recently, has just been diagnosed with a tumor in his belly and one in his head. I look at my own realvetcost.com, and it's one of the three most common conditions in Boxers.

I don't want to see the prognosis, but it's clear. How did it end?
