Affected dogs need to be isolated from other dogs and their bedding, and places they have occupied must be thoroughly cleaned. Other dogs in contact with a diagnosed case should be evaluated and treated. A number of parasitical treatments are useful in treating canine scabies. Sulfurated lime (a mixture of calcium polysulfides) rinses applied weekly or biweekly are effective (the concentrated form for use on plants as a fungicide must be diluted 1:16 or 1:32 for use on animal skin).

Selamectin is licensed for treatment in dogs by veterinary prescription in several countries; it is applied as a dose directly to the skin, once per month (the drug does not wash off). A related and older drug ivermectin is also effective and can be given by mouth for two to four weekly treatments or until two negative skin scrapings are achieved. Oral ivermectin is not safe to use on some collie-like herding dogs, however, due to possible homozygous MDR1 (P-glycoprotein) mutations that increase its toxicity by allowing it into the brain. Ivermectin injections are also effective and given in either weekly or every two weeks in one to four doses, although the same MDR1 dog restrictions apply.

Affected cats can be treated with fipronil and milbemycin oxime.

Topical 0.01% ivermectin in oil (Acarexx) has been reported to be effective in humans, and all mite infections in many types of animals (especially in ear mite infections where the animal cannot lick the treated area), and is so poorly absorbed that systemic toxicity is less likely in these sites. Nevertheless, topical ivermectin has not been well enough tested to be approved for this use in dogs, and is theoretically much more dangerous in zones where the animal can potentially lick the treated area. Selamectin applied to the skin (topically) has some of the same theoretical problems in collies and MDR1 dogs as ivermectin, but it has nevertheless been approved for use for all dogs provided that the animal can be observed for 8 hours after the first monthly treatment. Topical permethrin is also effective in both dogs and humans, but is toxic to cats.

Afoxolaner (oral treatment with a chewable tablet containing afoxolaner 2.27% w/w) has been shown to be efficient against both sarcoptic and demodectic mange in dogs.

Sarcoptic mange is transmissible to humans who come into prolonged contact with infested animals, and is distinguished from human scabies by its distribution on skin surfaces covered by clothing. For treatment of sarcoptic infection in humans, see scabies. For demodetic infection in humans, which is not as severe as it is in animals with thicker coats (such as dogs), see "Demodex folliculorum".

Permethrin is the most effective treatment for scabies, and remains the treatment of choice. It is applied from the neck down, usually before bedtime, and left on for about eight to 14 hours, then washed off in the morning. Care should be taken to coat the entire skin surface, not just symptomatic areas; any patch of skin left untreated can provide a "safe haven" for one or more mites to survive. One application is normally sufficient, as permethrin kills eggs and hatchlings, as well as adult mites, though many physicians recommend a second application three to seven days later as a precaution. Crusted scabies may require multiple applications, or supplemental treatment with oral ivermectin (below). Permethrin may cause slight irritation of the skin that is usually tolerable.

Other treatments include lindane, benzyl benzoate, crotamiton, malathion, and sulfur preparations. Lindane is effective, but concerns over potential neurotoxicity have limited its availability in many countries. It is banned in California, but may be used in other states as a second-line treatment. Sulfur ointments or benzyl benzoate are often used in the developing world due to their low cost; Some 10% sulfur solutions have been shown to be effective, and sulfur ointments are typically used for at least a week, though many people find the odor of sulfur products unpleasant. Crotamiton has been found to be less effective than permethrin in limited studies. Crotamiton or sulfur preparations are sometimes recommended instead of permethrin for children, due to concerns over dermal absorption of permethrin.

Localized demodectic mange is considered a common puppyhood ailment, with roughly 90% of cases resolving on their own with no treatment. Minor, localized cases should be left to resolve on their own to prevent masking of the more severe generalized form. If treatment is deemed necessary Goodwinol, a rotenone-based insecticide ointment is often prescribed, but it can be irritating to the skin. Demodectic mange with secondary infection is treated with antibiotics and medicated shampoos.

In more severe generalized cases, Amitraz is a parasiticidal dip that is licensed for use in many countries (the only FDA approved treatment in the USA) for treating canine demodicosis. It is applied weekly or biweekly, for several weeks, until no mites can be detected by skin scrapings. Demodectic mange in dogs can also be managed with avermectins, although there are few countries which license these drugs, which are given by mouth, daily, for this use. Ivermectin is used most frequently; collie-like herding breeds often do not tolerate this drug due to a defect in the blood–brain barrier, though not all of them have this defect. Other avermectin drugs that can be used include doramectin and milbemycin.

Recent results suggest that the isoxazolines afoxolaner and fluralaner, given orally, are effective in treating dogs with generalised demodicosis.

Cats with "Demodex gatoi" must be treated with weekly or bi-weekly sulfurated lime rinses. "Demodex cati" are treated similarly to canine demodicosis. With veterinary guidance, localized demodectic mange can also be treated with a topical keratolytic and antibacterial agent, followed by a lime sulfur drip or a local application of Rotenone. Ivermectin may also be used. Generalized demodectic mange in cats is more difficult to treat. There are shampoos available that can help to clear dead skin, kill mites and treat bacterial infections. Treatment is in most cases prolonged with multiple applications.

Because of the possibility of the immune deficiency being an inherited trait, many veterinarians believe that all puppies with generalized demodex should be spayed or neutered and not reproduce. Females with generalized demodex should be spayed because the stress of the estrus cycle will often bring on a fresh wave of clinical signs.

Treatment requires both systemic oral treatment with most of the same drugs used in humans—terbinafine, fluconazole, or itraconazole—as well as a topical "dip" therapy.

Because of the usually longer hair shafts in pets compared to those of humans, the area of infection and possibly all of the longer hair of the pet must be clipped to decrease the load of fungal spores clinging to the pet's hair shafts. However, close shaving is usually not done because nicking the skin facilitates further skin infection.

Twice-weekly bathing of the pet with diluted lime sulfur dip solution is effective in eradicating fungal spores. This must continue for 3 to 8 weeks.

Washing of household hard surfaces with 1:10 household sodium hypochlorite bleach solution is effective in killing spores, but it is too irritating to be used directly on hair and skin.

Pet hair must be rigorously removed from all household surfaces, and then the vacuum cleaner bag, and perhaps even the vacuum cleaner itself, discarded when this has been done repeatedly. Removal of all hair is important, since spores may survive 12 months or even as long as two years on hair clinging to surfaces.

In bovines, an infestation is difficult to cure, as systemic treatment is uneconomical. Local treatment with iodine compounds is time-consuming, as it needs scraping of crusty lesions. Moreover, it must be carefully conducted using gloves, lest the worker become infested.

Ear mites of dogs and cats can be treated with any of the spot-on preparations available from veterinary surgeons as well as over the counter at many pet stores and online. If the chosen solution does not destroy mite eggs, treatment should be repeated after one month, to catch the next generation of mites that will have hatched by then. Relief, in terms of the cat or dog no longer scratching at his or her ears, will be noticeable within a few hours. However, since mite irritation is partly allergic (see scabies), symptoms may also outlive mites by weeks. Moreover, it may take topical antibiotics and several weeks to clear infected external wounds caused by scratching on the exterior surfaces of cat and dog ears.

Common home remedy treatment options include household ingredients such as isopropyl alcohol, acetic acid (vinegar), boric acid, tea tree oil, coconut oil, and many other plant based extracts, in varying proportions.

Option for treating ear mites in rabbits are the related antiparasitics ivermectin and selamectin. Both of these antiparasitics have also been used with good effect in cats and dogs. A topical preparation of 0.01% ivermectin (Acarexx) can be used directly as an oil in cat ears, and the related new generation drug selamectin (brand name "Revolution") is available as a once-per-month skin treatment for both dogs and cats, which will prevent new mite infestation as well as a number of other parasitic diseases. As with ivermectin, selamectin must be used with caution in collies and herder breeds with the possibility for homozygous MDR1 mutations. A single treatment with a topical formulation containing fipronil, (S)-methoprene, eprinomectin and praziquantel was shown to be efficient for the prevention of "Otodectes cynotis" infestation in cats.

Good success has been noted by some with topical steroids such as triamcinolone and betamethasone applied to the lesions in conjunction with other treatments containing Kunzea.

Antiparasitic treatment is necessary only if mites or mange have been identified or if there is a need to repel insects such as Culicoides. Permethrins at concentration greater than 2%, fipronil spray or ivermectin orally have been used successfully. The essential oil of lemongrass (Cymbopogon citratus) is a good choice for a natural insect repellent.

Toxocariasis will often resolve itself, because the "Toxocara" larvae cannot mature within human hosts. Corticosteroids are prescribed in severe cases of VLM or if the patient is diagnosed with OLM. Either albendazole (preferred) or mebendazole (“second line therapy”) may be prescribed. Granulomas can be surgically removed, or laser photocoagulation and cryoretinopexy can be used to destroy ocular granulomas.

Visceral toxocariasis in humans can be treated with antiparasitic drugs such as albendazole or mebendazole, tiabendazole or diethylcarbamazine usually in combination with anti-inflammatory medications. Steroids have been utilized with some positive results. Anti-helminthic therapy is reserved for severe infections (lungs, brain) because therapy may induce, due to massive larval killing, a strong inflammatory response. Treatment of ocular toxocariasis is more difficult and usually consists of measures to prevent progressive damage to the eye.

Mange is a class of skin diseases caused by parasitic mites. Since mites also infect plants, birds, and reptiles, the term "mange", suggesting poor condition of the hairy coat due to the infection, is sometimes reserved only for pathological mite-infestation of nonhuman mammals. Thus, mange includes mite-associated skin disease in domestic animals (cats and dogs), in livestock (such as sheep scab), and in wild animals (for example, coyotes, cougars, and bears). Since mites belong to the arachnid subclass Acari (also called Acarina), another term for mite infestation is acariasis.

Parasitic mites that cause mange in mammals embed themselves either in skin or hair follicles in the animal, depending upon their genus. "Sarcoptes" spp. burrow into skin, while "Demodex" spp. live in follicles.

In humans, these two types of mite infections, which would otherwise be known as "mange" in furry mammals, are instead known respectively as scabies and demodicosis.

For demodectic mange, properly performed deep skin scrapings generally allow the veterinarian to identify the microscopic mites. Acetate tape impression with squeezing has recently found to be a more sensitive method to identify mites. It was originally thought that because the mite is a normal inhabitant of the dog's skin, the presence of the mites does not conclusively mean the dog suffers from demodex. Recent research, however, found that demodex mite can hardly be found on clinically normal dogs, meaning that the presence of any number of mites in a sample is very likely to be significant. In breeds such as the West Highland White Terrier, relatively minor skin irritation which would otherwise be considered allergy should be carefully scraped because of the predilection of these dogs to demodectic mange. Skin scrapings may be used to follow the progress of treatment in demodectic mange.

Alternatively, plasma levels of zinc and copper have been seen to be decreased in dogs suffering with demodicosis. This may be due to inflammation involved in the immune response of demodicosis which can lead to oxidative stress resulting in dogs suffering from demodicosis to exhibit higher levels of antioxidant productivity. The catalases involved in the antioxidant pathway require the trace minerals zinc and copper. Dogs with demodicosis show a decrease in plasma copper and zinc levels due to the increased demand for antioxidant activity. Therefore, this may be considered as a potential marker for demodicosis.

Topical treatments such as warm compresses to the chin area may be sufficient for mild cases. Veterinary intervention may be required for treatment if secondary infection occurs. In this case, treatment may begin with clinical drainage of the pustules and a course of oral antibiotics.

Clearing the acne can be accomplished using an old toothbrush or flea comb (one designated for this purpose) and brush the cat's chin. This will loosen debris and remove dried scabs. Cleansing pads containing salicylic acid can be rubbed gently and allowed to air dry on the affected area. This may dissolve the oil that is clogging skin pores. Epsom-salt compresses applied twice daily dry the affected area to relieve the inflammation and itchiness.

Scaly foot, or knemidocoptiasis is a bird ailment that is common among caged birds and also affects many other bird species. It is caused by mites in the genus "Knemidocoptes" which burrow into the bird's flesh. The tunnels made by the mites within the skin cause dermatitis and scaly lesions. Scaly face is caused by the same mite responsible for scaly foot and other related mites cause depluming. The condition is transmitted from one bird to another by direct prolonged contact.

Placing the cat's water in a shallow dish may prevent the chin from absorbing the bacteria in the water while the cat is drinking. If the cat is allergic to plastics or dyes, using a stainless-steel or glass dish is recommended . Cats may also have food allergies that make the development of acne more likely, so that switching kibble, or changing to a hydrolysed diet may be effective. Maintaining good hygiene and grooming habits make the development of feline acne less likely. Washing and exfoliating the chin with a gentle benzoyl-peroxide solution also may be preventive of further outbreaks.

Scaly foot, otherwise known as knemidocoptiasis, is caused by burrowing mites in the genus "Knemidocoptes". The condition can be compared with sarcoptic mange in mammals, but does not seem to cause the same level of itching. The birds chiefly affected are galliformes (chickens and turkeys), passerines (finches, canaries, sparrows, robins, wrens), and psittacine birds (parrots, macaws, parakeets, budgerigars). The condition sometimes additionally affects piciformes (woodpeckers, toucans) and anseriformes ducks, geese, swans), raptors and other birds. The two species of mite most often implicated are "K. jamaicensis" and "K. intermedius". Other related species of mite affect feather follicles and cause depluming. The mites are mostly transmitted by prolonged direct contact, particularly from parent bird to unfledged nestling.

There is not enough evidence to recommend alternative medicine such as tea tree oil or honey.

For generations, the disease was treated with an application of the antiseptic gentian violet. Today, topical or oral antibiotics are usually prescribed. Mild cases may be treated with bactericidal ointment, such as mupirocin. In 95% of cases, a single antibiotic course results in resolution in children. It has been advocated that topical disinfectants are not nearly as efficient as antibiotics, and therefore should be avoided.

More severe cases require oral antibiotics, such as dicloxacillin, flucloxacillin, or erythromycin. Alternatively, amoxicillin combined with clavulanate potassium, cephalosporins (first-generation) and many others may also be used as an antibiotic treatment. Alternatives for people who are seriously allergic to penicillin or infections with MRSA include doxycycline, clindamycin, and SMX-TMP. When streptococci alone are the cause, penicillin is the drug of choice.

When the condition presents with ulcers, valacyclovir, an antiviral, may be given in case a viral infection is causing the ulcer.

The rabbit ear mite, "Psoroptes cuniculi", is larger than "Otodectes cynotis". It causes thick firm debris to form in the ear canal, and can eventually migrate to the skin of the outer ear and face. Symptoms include scratching and shaking of the head. Treatment includes topical selamectin, or injections of ivermectin and frequent cleanings of the rabbit's environment.

Medications with good evidence include ivermectin and azelaic acid creams and brimonidine, doxycycline, and isotretinoin by mouth. Lesser evidence supports metronidazole cream and tetracycline by mouth.

Metronidazole is thought to act through anti-inflammatory mechanisms, while azelaic acid is thought to decrease cathelicidin production. Oral antibiotics of the tetracycline class such as doxycycline and oxytetracycline are also commonly used and thought to reduce papulopustular lesions through anti-inflammatory actions rather than through their antibacterial capabilities.

Using alpha-hydroxy acid peels may help relieve redness caused by irritation, and reduce papules and pustules associated with rosacea. Oral antibiotics may help to relieve symptoms of ocular rosacea. If papules and pustules persist, then sometimes isotretinoin can be prescribed.

The flushing and blushing that typically accompanies rosacea is typically treated with the topical application of alpha agonists such as brimonidine and less commonly oxymetazoline or xylometazoline.

Some treatments for infection with "Toxocara cati" include drugs designed to cause the adult worms to become partially anaesthetized and detach from the intestinal lining, allowing them to be excreted live in the feces. Such medications include piperazine and pyrantel. These are frequently combined with the drug praziquantel which appears to cause the worm to lose its resistance to being digested by the host animal. Other effective treatments include ivermectin, milbemycin, and selamectin. Dichlorvos has also been proven to be effective as a poison, though moves to ban it over concerns about its toxicity have made it unavailable in some areas.

Treatment for wild felids, however, is difficult for this parasite, as detection is the best way to find which individuals have the parasite. This can be difficult as infected species are hard to detect. Once detected, the infected individuals would have to be removed from the population, in order to lower the risk of continual exposure to the parasites.

A primary method that has been used to lower the amount of infection is removal through hunting. Removal can also occur through landowners, as Dare and Watkins (2012) discovered through their research on cougars. Both hunters and landowners can provide samples that can be used to detect the presence of feline roundworm in the area, as well as help remove it from the population. This method is more practical than administering medications to wild populations, as wild animals, as mentioned before, are harder to find in order to administer medicinal care.

Medicinal care, however, is also another method used in round worm studies; such as the experiment on managing raccoon roundworm done by Smyser et al. (2013) in which they implemented medical baiting. However, medicine is often expensive and the success of the baiting depends on if the infected individuals consume the bait. Additionally, it can be costly (in time and resources) to check on baited areas. Removal by hunting allows agencies to reduce costs and gives agencies a more improved chance of removing infected individuals.

Medical doctors and dermatologists can still misdiagnose this rash as many are unfamiliar with parasitism, not trained in it, or if they do consider it, cannot see the mites.

Different methods for detection are recognized for different acariasis infections. Human acariasis with mites can occur in the gastrointestinal tract, lungs, urinary tracts and other organs which not have been well-studied. For intestinal acariasis with symptoms such as abdominal pain, diarrhea, and phohemefecia (is this hemafecia?), human acariasis is diagnosed by detection of mites in stools. For pulmonary acariasis, the presence of mites in sputum is determined by identifying the presence and number of mites in the sputum of patients with respiratory symptoms. Both physical and chemical methods for liquefaction of sputum have been developed.

Dermatological vascular laser (single wavelength) or intense pulsed light (broad spectrum) machines offer one of the treatments for rosacea, in particular the erythema (redness) of the skin. They use light to penetrate the epidermis to target the capillaries in the dermis layer of the skin. The light is absorbed by oxyhemoglobin, which heats up, causing the capillary walls to heat up to 70 °C (158 °F), damaging them, and causing them to be absorbed by the body's natural defense mechanism. With a sufficient number of treatments, this method may even eliminate the redness altogether, though additional periodic treatments will likely be necessary to remove newly formed capillaries.

CO lasers can be used to remove excess tissue caused by phymatous rosacea. CO lasers emit a wavelength that is absorbed directly by the skin. The laser beam can be focused into a thin beam and used as a scalpel or defocused and used to vaporize tissue. Low-level light therapies have also been used to treat rosacea. Photorejuvenation can also reportedly be used to improve the appearance of rosacea and reduce the redness associated with it.

For simple cases of cystic echinococcosis, the most common form of treatment is open surgical removal of the cysts combined with chemotherapy using albendazole and/or mebendazole before and after surgery. However, if there are cysts in multiple organs or tissues, or the cysts are in risky locations, surgery becomes impractical. For inoperable cases such as these, chemotherapy and/or PAIR (puncture-aspiration-injection-reaspiration) become alternative options of treatment. In the case of alternative treatment using just chemotherapy, albendazole is preferred twice a day for 1–5 months. An alternative to albendazole is mebendazole for at least 3 to 6 months. The other alternative to surgery is PAIR with chemotherapy. PAIR is a minimally invasive procedure that involves three steps: puncture and needle aspiration of the cyst, injection of a scolicidal solution for 20–30 min, and cyst-re-aspiration and final irrigation. Patients who undergo PAIR typically take albendazole or mebendazole from 7 days before the procedure until 28 days after the procedure. While open surgery still remains as the standard for cystic echinococcosis treatment, there have been a number of studies that suggest that PAIR with chemotherapy is more effective than surgery in terms of disease recurrence, and morbidity and mortality. In addition to the three above mentioned treatments, there is currently research and studies looking at new treatment involving percutaneous thermal ablation (PTA) of the germinal layer in the cyst by means of a radiofrequency ablation device. This form of treatment is still relatively new and requires much more testing before being widely used. An alternative to open surgery is laparoscopic surgery, which provides excellent cure rates with minimal morbidity and mortality.

For alveolar echinococcosis, surgical removal of cysts combined with chemotherapy (using albendazole and/or mebendazole) for up to two years after surgery is the only sure way to completely cure the disease. However, in inoperable cases, chemotherapy by itself can also be used. In treatment using just chemotherapy, one could use either mebendazole in three doses or albendazole in two doses. Since chemotherapy on its own is not guaranteed to completely rid the patient of disease, patients are often kept on the drugs for extended periods of times (i.e. more than 6 months, years). In addition to surgery and chemotherapy, liver transplants are being looked into as a form of treatment for alveolar echinococcosis although it is seen as incredibly risky since it often leads to echinococcosis re-infection in the patient afterwards.
