What is Sarcoptic Mange?

Sarcoptic mange is a type of skin infection which is most commonly seen in dogs, although it can appear temporarily in humans, cats, and other animals. Like other conditions known as “mange,” sarcoptic mange is characterized by the development of crusty skin, small lesions, hair loss, and intense itching on the body. Pet owners need to have the dog examined at a veterinarian to confirm the diagnosis of sarcoptic mange and to obtain the most effective treatment, as several related skin conditions look similar, and require different treatment.

This condition is caused by an infection with the Sarcoptes scabiei canis mite, a close relative of the mite which causes scabies in humans. Sarcoptic mange is sometimes referred to as “canine scabies” or “scabies,” which can cause some confusion, as the mites which infect dogs and humans are actually slightly different. The mites burrow into the skin for the purpose of laying eggs, causing inflammation, itching, and the development of numerous small red pustules.

The initial infection can be painful and debilitating, and it can be worsened as the dog scratches or bites at the affected areas, causing a secondary infection to set in. The dog may injure itself with desperate scratching, causing large lesions and cuts to appear. If the infection is allowed to persist, it will slowly spread, moving from the abdomen and legs up to the head and the margins of the ears and causing considerable discomfort.

A veterinarian can sometimes diagnose sarcoptic mange which a skin scraping. The scraping can also be used to rule out other causes of infection, such as demodectic mange. If the skin scraping reveals the presence of scabies mites or rules out other causes, the veterinarian can prescribe treatments such as dips, topical lotions, shampoos, pills, or injections.

It is important to be aware that some treatments are dangerous for certain dog breeds, and that treatments designed for use on other animals may not work on dogs. Likewise, a mange treatment for dogs will not be effective on other animals, and it could even be dangerous. For example, permethrin creams which are commonly used to manage insect infestations on dogs are deadly for cats. Folk remedies such as topical applications of motor oil and other substances are also very dangerous.

If one dog in a household has sarcoptic mange, chances are high that other dogs will have it also, and they should be treated at the same time. If an infected dog has playmates or friends, their owners should be informed so that they can treat their dogs as well. Dogs with sarcoptic mange should be isolated from other animals and people in the household, and their bedding should be washed thoroughly in extremely hot water to remove mites and eggs.

Frequently Asked Questions

What is sarcoptic mange and how is it caused?

Sarcoptic mange, also known as scabies, is a highly contagious skin disease found in animals, caused by the Sarcoptes scabiei mite. These microscopic mites burrow into the skin, causing intense itching and irritation. Infestation typically occurs through direct contact with an infected animal or contaminated environment.

What are the symptoms of sarcoptic mange in animals?

Animals with sarcoptic mange exhibit severe itching, redness, and rash, often leading to hair loss and the formation of scabs and sores from persistent scratching. Secondary infections can occur due to the compromised skin. Symptoms usually appear one to three weeks after exposure, according to veterinary sources.

Can sarcoptic mange be transmitted to humans?

Yes, sarcoptic mange can be transmitted to humans, causing a condition known as scabies. Human infection typically results in temporary skin irritation and itching, as the mites cannot complete their life cycle on humans. Close contact with infected animals increases the risk of transmission.

How is sarcoptic mange diagnosed in animals?

Diagnosis of sarcoptic mange is often based on clinical signs and the presence of mites in skin scrapings examined under a microscope. However, mites can be difficult to find, so veterinarians may also rely on response to treatment or serological tests for a definitive diagnosis.

What treatments are available for sarcoptic mange?

Treatment for sarcoptic mange typically involves prescribed antiparasitic medications, such as topical selamectin or oral ivermectin. Environmental decontamination is also crucial to prevent reinfestation. Severely affected animals may require additional treatments for secondary infections or to alleviate severe itching.

How can sarcoptic mange be prevented?

Preventing sarcoptic mange involves minimizing exposure to infected animals and maintaining a clean environment. Regular veterinary check-ups and using preventive medications can also help. In kennels or shelters, strict hygiene and isolation of infected animals are key to controlling outbreaks.

@Vincenzo -- I'm not sure I like the idea of diagnosing your dog with sarcoptic mange like that. You should always go to the vet for the right tests and diagnosis.

Otherwise, you could wind up treating the wrong thing and I am not sure if you need to be dumping mange treatment all over a dog that doesn't have the mange.

Vincenzo

If you have been to the vet once and learned you have a dog with sarcoptic mange, you can easily tell if subsequent dogs become affected. The good news is that mange is fairly easy to treat with the right kind of shampoo that is readily available at your local pet store.

If you think your dog has mange, just grab some of that treatment shampoo, follow the directions and save yourself a vet bill. Pretty easy, really.
