Itchy. Contagious. Miserable.
The burrowing carnivorous mite Sarcoptes Scabiei is responsible for causing Sarcoptic Mange. It is sometimes known as the scabies mite or the itch mite.
The microscopic flesh eaters gnaw through the skin, creating a maze of damage and causing what is considered to be the itchiest type of mange.
Good to know:
- Zoonotic – highly contagious to people & other pets
- Fast, mobzile & invasive. Penetrates in 25–30 minutes
- Will infest homes, cars, yards, other pets & people
- Every person & pet is potentially both a carrier and victim
- Invisible flesh-eaters
Sarcoptic mites (sarcoptes scabiei) are flesh eating mites that tunnel deeper and deeper as they chew through your dog. A fair comparison is an ant farm, only in this cast it’s microscopic.
Your dog just picked the contagious creeps up somewhere. Innocently being in the wrong place at the wrong time where the wrong critters are can cause a world of misery. (It’s helpful if you can backtrack to determine where transmission happened so you can avoid returning to the scene of the crime. The last thing you want is more parasites keeping you & your pack company.)
Sarcoptic mange in dogs can be transmitted two ways: directly and indirectly. Most people associate Sarcoptic mange with direct transmission. That’s when the mites are passed by casual contact with an infested host (pet, person, or even wildlife) in a physical setting. Indirect transmission happens in an environment with no host present. A dislodged mite can survive up to 5 days on their own. Merely visiting an area where an infested host has deposited a few mites can cause your dog to become a victim in no time.
Mites get hungry when they’re off of a host. These starving speed demons sense available food sources through heat and odor, so a nearby is likely to be the parasites’ next meal.
All it takes is one fertile female to start the cycle. She will begin laying eggs within 2 hours of infesting the dog; which hatch in 2-4 days. After being fertilized just once, she will lay up to 90 eggs in her lifetime.
Sarcoptic mange almost always brings severe itching as the mites carve a maze of tunnels throughout the dogs epidermis.
Some degree of hair loss is almost always a given as well. Other possible symptoms include red and inflamed skin, crusty ear tips, and red pustules with yellow crusts. Commonly affected areas include elbows, ears, armpits, hocks, chest, and belly, as these mites usually prefer areas that have less hair. As the mange worsens it can spread over the entire body.
More subtle signs may include lethargy, depression, loss of appetite, and weight loss. Intense discomfort can lead to nervous, restless or agitated behavior and possibly a habitual scratching habit.
If the infestation goes untreated or is mistakenly treated, the skin may darken due to the constant irritation, and the surrounding lymph nodes may become enlarged.
Good to know:
- Sleep deprivation not uncommon due to nocturnal scratching
- Symptoms begin to appear about 10 days after exposure
- Bite Marks may be visible on the surface of the skin
- Itching may intensify in warm conditions
- Unlike allergies, itching is non-seasonal
- Self-injury or infection nay result from heavy scratching and biting
Good to know:
- A negative skin scraping does not rule out any type of mange. It only means no mites were captured at that time.
- Owner diagnosis is common.
- Please visit our Symptom Checker for more symptoms.
Sarcoptic mange is clinically diagnosed by examining skin scrapings under a microscope and identifying sarcoptes scabiei. Obtaining a definitive diagnosis is difficult with this method as they are fast and difficult is to catch. Only 20% of cases have a positive scrape.
If the skin scraping is negative, that particular diagnosis is ruled out and a different treatment is prescribed for the next likely disorder.
The downside of this method is the dog continues to suffer, the mange worsens and there is a risk of side effects from the unnecessary medications.
In addition to the symptoms above, a telltale sign that may help with self-diagnosis is that other people and/or pets in your house start itching. Symptoms begin to appear about 10 days after exposure.
A simple home test known as the pinna-pedal reflex test is reportedly about 85% accurate in detecting Sarcoptes mites Vigorously rub one earflap, moving from the tip down to the base of the ear for at least five seconds. A positive result is indicated by the hind leg moving as if to scratch the ear. Ears usually have the mites and their sensitivity triggers a scratching reflex. Here is a video of one being performed.

Your Treatment Options
Clinicians can prescribe many different treatments for mange The same drugs are used for Sarcoptic, Demodectic and Cheyletiella mange. They are neurotoxic chemical pesticides such as ivermectin, amitraz and doramectin are often used. Unfortunately, mites are quickly developing resistance to them.
Topical spot-on pesticides like Revolution®, Advantage Multi®, Advocate®, Frontline®, etc. have a very low rate of success. Ivermectin is the go-to option for internally poisoning the mites and Mitiban (amatraz) is a popular prescription dip. Ivermectin does not have FDA approval for treating mange and is used off-label. It, like all chemical treatments, is a systemic neurotoxin. Drugs take 2 months or mire to eliminate a Sarcoptes infestation then they stay in a dog’s system well after treatment has stopped. And after the poison has done its job it can take several more weeks for the itchiness (pruritis) to resolve.
Most chemicals do not kill on contact; the kill is delayed as the mites’ nervous system is slowly destroyed. The drugs systemically spread throughout the entire body even though only the upper layers of skin are affected. They all come with long lists of potential side effects, with amitraz being the most dangerous of them all. Bravecto, a relatively new drug on the scene, has a grassroots following that would love to see it banned (just read the facebook page Does Bravecto Kill Dogs).
Check out the warnings and cautions about amatraz, over in the sidebar. The drug used in small doses in flea & tick collars. Roughly 50X more is needed for mange. Amitraz is most commonly used as a dip. The dog is shaved and its largest organ, the skin, is drenched with one of the most noxious poisons used to treat mange. Because it is absorbed so fast and spread through capillary action, strong side effects can kick in quickly.
The same properties that kill mites can also cause neurological and physiological reactions in dogs. The rate of side effects is high while their failure rate is roughly 30%.
In addition to chemical parasiticides, antihistamines and steroid medications (corticosteroids) are often given as part of treatment. Antihistamines may or may not relieve itchiness and broad spectrum antibiotics are prescribed whether secondary infections is present or not.
Even though some dogs do just fine, as more information about chemical treatments is revealed, a greater number of responsible pet guardians are looking for an alternative.
Animal safety studies suggest amitraz may alter the animal’s ability to maintain homeostasis. Animals treated with MITABAN (amitraz) should not be subjected to stress or handled for a period of at least 24 hours post-treatment. Adverse reactions including three fatalities were reported during the clinical studies of 1100 dogs with generalized demodicosis treated with MITABAN. (Um, one death is too many guys.)
Studies report that using an antidote for those amitraz poisoning with miosis or bradycardia resolved the problem. (An antidote? Really?)
Amitraz poisoning is associated with symptoms varying from central nervous system depression (drowsiness, coma, and convulsion), excessive dilation or constriction of the pupils, respiratory depression, slow heart rate, low or high blood pressure, abnormally low body temperature or fever, high blood sugar, excessive urination, vomiting, decreased gastrointestinal motility (17 different disorders), and intestinal distension. Other less serious side effects: allergic reaction (difficulty breathing; swelling of the lips, tongue or face; hives), severe headache, restlessness, agitation, irritability, sweating, uncontrollable or irregular movements, dizziness, insomnia, mild confusion, anxiety, dry mouth. Other side effects are also possible. (For those not counting, that’s 45 named side effects, maybe more!)
Good to know:
- Chemical treatments are neurotoxic poisons that kill by damaging the mites’ central nervous system. These same chemicals infiltrate every organ and cell, even where there are no mites.
- Reactions and side effects occur but due to sketchy reporting regulations there is no accurate data.
- Herding breeds such as Australian Shepherds, Border Collies, English Shepherds, Collies do not tolerate chemical treatments well. Fatalities have occurred.
Natural Sarcoptic Mange Treatment
Treating mites naturally is absolutely the safest way to go and in our opinion, the kindest. Nature provides us with powerful substances to treat mange without further insulting an animal’s health.
Eliminating Sarcoptic mange with Mite Avenge gets your dog out of misery quickly. Most dogs feel remarkably better within a day or two and the entire process is complete in 2 weeks. Average cases require 3 treatments of Mite Avenge, once every 7 days. This breaks the sarcoptes scabiei life cycle far faster than chemicals.
Mite Avenge’s natural miticides are gentle, have nearly zero chance of reactions or side effects, are non-chemical, non-toxic, and mites cannot become immune to them. It’s the most effective natural mange cure you’ll find. It’s safe, highly effective and in the long run, generally more cost-effective all while being merciless on mites.
The Mite Avenge 3-bottle easy kit is appropriate for most single dog situations. (Severe infestations and certain sizes of dogs may take slightly longer.) Other helpful but not mandatory supples are also listed on the Easy kit page.
With Mite Avenge, household decontamination is a key part of our short treatment cycle and is essential to avoiding reinfestation. Here’s a complete rundown of everything you need to do.
Well, what are you waiting for? Go get started!
Good to know:
- With both chemical and natural treatments, all household dogs must be treated whether they are symptomatic or not.
- Mite Avenge’s performance can be enhanced by using Flush & Kill Shampoo before a treatment.
- Reinfestation common without household decontamination
- Avoid returning to areas where you suspect transmission occurred
- No preventative measures for Sarcoptic mange.
