Homeopathic products are mainly produced from natural ingredients such as plants and minerals, making them gentle enough for wildlife and pets.Over the counter remedies are most commonly labelled as either 6C or 30C. These descriptions indicate how diluted the active ingredient is; for example, 6C has undergone six steps in a series of dilutions. Each step involves adding 1 part of the active ingredient to 99 parts of water or alcohol, meaning that 30C is more diluted than 6C.
The History of Homeopathy
The common belief in homeopathy is that the remedy becomes more potent the more it is diluted. These observations have been recorded since the 18 th century, but homeopathy began its journey long before this.
The idea dates back to Hippocrates between 460-377 BC. However, it wasn't until the 18th century that German physician Samuel Hahnemann devised the basis of homeopathy that we know today.
Homeopathy Uses
Sarcoptic mange, also known as canine scabies, is a highly contagious infestation of Sarcoptes scabiei canis, a burrowing mite. The canine sarcoptic mite can also infest cats, pigs, horses, sheep, and various other species. The human analog of burrowing mite infection, due to a closely related species, is called scabies (the "seven year itch").
All these burrowing mites are in the family Sarcoptidae. They dig into and through the skin, causing intense itching from an allergic reaction to the mite, and crusting that can quickly become infected. Hair loss and crusting frequently appear first on elbows and ears. Skin damage can occur from the dog's intense scratching and biting. Secondary skin infection is also common. Dogs with chronic sarcoptic mange are often in poor condition, and in both animals and humans, immune suppression from starvation or any other disease causes this type of mange to develop into a highly crusted form in which the burden of mites is far higher than in healthy specimens.
Homeopathic products are used for a number of health complaints. We stock a variety of products including our Sarcoptic Mange remedy.
Demodectic mange
Also called demodicosis or red mange, demodectic mange is caused by a sensitivity to and overpopulation of Demodex canis. The two types of demodectic mange are localized and generalized. Localized consists of four spots or less. It is not contagious to humans.
Arthur Stanley Hirst, a noted authority on Acari states "In typical cases of this complaint the mites are found in enormous numbers, but Friedrich Gmeiner and also Albert E. Mettam have shown that D. canis is not the actual cause of follicular mange, which is due to a bacterium Staphylococcus epidermidis or some allied form. The mite plays an important part in the disease, however, by preparing the ground for the invasion of the bacterium by dilating the follicles and sweat-glands, and possibly also carries and introduces the germ. Whilst the Acari remain in the follicles or sweat-glands some of the bacteria may penetrate more deeply and be conveyed from one point to another by the blood-stream."
A type of demodectic infection in humans is known, but is less commonly symptomatic
Sarcoptic mange

Dogs with chronic sarcoptic mange are often in poor condition, and in both animals and humans, immune suppression from starvation or any other disease causes this type of mange to develop into a highly crusted form in which the burden of mites is far higher than in healthy specimens.
Diagnosis
Veterinarians usually attempt diagnosis with skin scrapings from multiple areas, which are then examined under a microscope for mites. Sarcoptes mites, because they may be present in relatively low numbers, and because they are often removed by dogs chewing at themselves, may be difficult to demonstrate. As a result, diagnosis in sarcoptic mange is often based on symptoms rather than actual confirmation of the presence of mites. A common and simple way of determining if a dog has mange is if it displays what is called a "pedal-pinna reflex", which is when the dog moves one of its hind legs in a scratching motion as the ear is being manipulated and scratched gently by the examiner; because the mites proliferate on the ear margins in nearly all cases at some point, this method works over 95% of the time.It is helpful in cases where all symptoms of mange are present but no mites are observed with a microscope. The test is also positive in animals with ear mites, an ear canal infection caused by a different but closely related mite (treatment is often the same). In some countries, an available serologic test may be useful in diagnosis.
Treatment
Affected dogs are sometimes 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 miteinfections 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[7] [8] and demodectic[9] mange in dogs.
Sarcoptic mange is transmissible to humans who come into prolonged contact with infested animals,[10] 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)
