Seeing your dog constantly chew at their skin is heartbreaking. You notice a small bald patch. Then another. Pretty soon, your house smells like old gym socks and your best friend looks like they’ve been through a paper shredder. If you're trying to figure out how to get rid of mange in dogs, you’ve likely realized this isn’t just a simple case of fleas. It’s microscopic mites. It’s an invisible war happening in the hair follicles.
Mange is a bit of a "catch-all" term that scares people, but it’s actually two very different beasts. Honestly, treating the wrong one is a massive waste of time and money. You’ve got Sarcoptic mange, which is basically the canine version of scabies, and then there’s Demodectic mange. One is a highly contagious nightmare that can jump to you; the other is mostly about your dog’s immune system hitting a glitch.
The Scabies Scare: Dealing with Sarcoptic Mites
Sarcoptic mange is the one that makes everyone jumpy. These mites, specifically Sarcoptes scabiei var. canis, are burrowers. They don't just sit on the skin; they tunnel through it like tiny, angry miners. This causes an allergic reaction that is, frankly, legendary in the veterinary world for how much it hurts and itches.
If your dog has crusty ear edges or "elbow sores," you’re likely looking at Sarcoptes. Dr. Jerry Klein, the Chief Veterinary Officer for the AKC, often points out that this version is "zoonotic." That's a fancy way of saying you can catch it. You won't become a permanent host—human skin isn't their favorite flavor—but you’ll get red, itchy bumps until the dog is cleared up.
How do you actually kill them?
Forget the old-school "motor oil" myths. That’s dangerous and can give your dog lead poisoning. Today, we have much better options. Most vets are going to steer you toward Isoxazoline medications. You might know them by brand names like Bravecto, Simparica, or NexGard. These were originally for fleas and ticks, but they’ve been found to be absolute nukes against mange mites.
Usually, a single dose starts killing mites within hours. However, since the mites have a life cycle of about 21 days, most pros recommend a second dose a month later to ensure the "grandkids" of the original mites are dead too.

You also have to think about the "secondary" stuff. The mites cause the itch, but the dog's scratching causes the infection. If the skin is oozing or smells like yeast, your vet will probably hand you a bottle of Cephalexin or a similar antibiotic. Without fixing the skin barrier, the mites are only half the battle.
Demodex: The Mite That’s Already There
This is the weird part. Your dog already has mites. Right now. Demodex canis lives in the hair follicles of almost every healthy dog on the planet. They usually just hang out and mind their own business.
Problems start when the immune system takes a nap. This is why you see "localized" Demodex in puppies—their immune systems are still learning the ropes. They get a few bald spots around the eyes or mouth. Usually, these clear up on their own as the pup grows. But "generalized" Demodex? That’s a whole different story.
When an adult dog suddenly gets covered in Demodex, it’s a red flag. It usually means something else is wrong—maybe diabetes, cancer, or a massive thyroid issue—that is distracting the immune system.
Treatment nuances for Demodectic Mange
For a long time, the only way to treat this was Amitraz dips (Mitaban). If you’ve ever smelled it, you know it's basically liquid poison. It makes the dogs lethargic and smells like a chemical plant. Thankfully, it’s mostly a thing of the past.

Again, those oral flea and tick meds (the Isoxazolines) have revolutionized this. Studies published in journals like Veterinary Dermatology have shown that drugs like afoxolaner (NexGard) are nearly 100% effective against Demodex. It's much kinder on the dog's liver than the old dips.
The "Home Remedy" Trap
You’ll see a lot of people online swearing by apple cider vinegar or coconut oil. Let's be real: these can help soothe the skin, but they won't kill a deep-seated mite infestation. Vinegar is acidic; if your dog has open sores from scratching, pouring vinegar on them is basically torture.
Coconut oil is a great moisturizer. It might suffocate a couple of mites on the surface, but it won't reach the ones deep in the follicles. Use it as a topper to help the skin heal, but don't rely on it as the "cure."
Deep Cleaning Your Life
If you’re dealing with Sarcoptic mange, your house is now a crime scene. These mites can live off the host for a few days. You need to wash every blanket, bed, and plush toy in the hottest water the fabric can stand. Vacuum the rugs. Throw away the vacuum bag immediately.
If it's Demodectic mange, you can relax a bit on the cleaning. Since those mites are part of the normal "fauna" of a dog, they aren't going to infest your carpet and jump on your neighbor's poodle. Focus more on high-quality nutrition—think Omega-3 fatty acids and probiotics—to get that immune system back in the fight.

Why "Wait and See" is a Bad Idea
Mange isn't just a cosmetic issue. When the skin barrier breaks down, it opens the door for Staphylococcus infections. This can lead to sepsis in extreme cases. Also, the constant "itch-scratch" cycle causes massive spikes in cortisol (the stress hormone), which further weakens the immune system. It’s a literal downward spiral.
Check the Paws
One specific thing people miss is "Demodectic Pododermatitis." This is when the mites move into the paws. It’s notoriously hard to treat because the skin there is so thick. If your dog is limping or their paws look swollen and "heavy," mention this specifically to your vet. It often requires a much longer course of medication than skin-based mange.
The Road to Recovery
It takes time. You’ll see the itching stop within a week or two of starting the right meds, but the hair? That can take months to grow back. Sometimes the skin stays dark or "elephant-like" for a while. That's hyperpigmentation from the chronic inflammation.
- Get a Skin Scraping: Don't guess. A vet needs to press a scalpel blade (gently!) against the skin to collect cells and look at them under a microscope. Seeing the mite tells you exactly which "war" you're fighting.
- Standardize the Meds: Ask about the once-a-month oral chewables. They are the gold standard in 2026 for mite control.
- Bathe with Medicated Shampoo: Look for ingredients like Benzoyl Peroxide. It’s "follicle flushing," meaning it gets deep into the pores where the mites hide.
- Boost the Diet: Switch to a limited-ingredient diet or something high in Zinc and Vitamin E to support skin regeneration.
- Environment Control: For Sarcoptes, use an environmental spray meant for mites and fleas on your baseboards and furniture.
Mange is gross, sure. It’s frustrating. But unlike 20 years ago, it is no longer a "death sentence" or a reason to give up a dog. With the right oral medication and a bit of patience with the vacuum cleaner, your dog will have their coat back before you know it.
