Understanding Parasitic Skin Disease in Dogs
Mange is a skin disease caused by microscopic mites that live on or within the skin. These parasites can cause itching, inflammation, and hair loss, and in some cases can lead to serious skin infections if left untreated.
Several types of mites can affect dogs, but the two most common forms of mange are sarcoptic mange and demodectic mange.
Although the symptoms may appear similar, these two conditions develop for different reasons and require different approaches to treatment.
Types of Mange in Dogs
Sarcoptic Mange (Scabies)
Sarcoptic mange is caused by the mite Sarcoptes scabiei. These mites burrow into the skin and cause severe itching and irritation.
Dogs with sarcoptic mange often show symptoms such as:
intense scratching
hair loss
red or inflamed skin
crusting or scabs on the skin
The ears, elbows, chest, and abdomen are commonly affected areas.
Sarcoptic mange is highly contagious between dogs, and in some cases can temporarily irritate human skin.
Demodectic Mange (Demodicosis)
Demodectic mange is caused by mites from the Demodex species. These mites normally live in small numbers in hair follicles and are usually harmless.
However, if a dog’s immune system is immature or weakened, the mites may multiply excessively and cause skin disease.
Demodectic mange often causes:
patchy hair loss
mild redness
scaling of the skin
Unlike sarcoptic mange, demodectic mange is not contagious.
It is most commonly seen in young dogs or dogs with immune system problems.
Signs of Mange in Dogs
The symptoms of mange vary depending on the type of mite involved.
Common signs include:
intense itching or scratching
hair loss
red or inflamed skin
crusts or scabs on the skin
thickened or darkened skin in chronic cases
Dogs with severe mange may also develop secondary bacterial skin infections, which can worsen itching and discomfort.
How Veterinarians Diagnose Mange
Diagnosing mange usually involves identifying the mites responsible for the skin disease.
Veterinarians may perform diagnostic tests such as:
skin scrapings examined under a microscope
hair or skin samples
additional testing if infection is present
Because mites can sometimes be difficult to detect, veterinarians may also consider the dog’s history and clinical signs when making a diagnosis.
Treatment for Mange
Treatment depends on the type of mange and the severity of the infection.
Modern veterinary treatments for mange may include:
oral parasite medications
topical treatments
medicated shampoos
treatment for secondary skin infections
Most dogs respond well to treatment when the condition is diagnosed early.
Preventing Mange
Preventing parasite infestations is an important part of maintaining your dog’s skin health.
Preventive steps include:
regular parasite prevention
avoiding contact with infected animals
routine veterinary checkups
Early treatment of skin problems can help prevent more serious infections from developing.
