What is it?
Sarcoptic mange is a contagious skin disease caused by a microscopic mite that burrows under the skin. It mainly affects dogs, but also cats and rabbits, and can be transmitted to humans. It causes severe itching and significant skin lesions.

The main signs are intense itching, often accompanied by redness, crusts and hair loss, especially on the ears, elbows and stomach. The skin may thicken and become rough over time. The animal often scratches to the point of injuring itself.
When to consult without delay
This list does not replace veterinary advice. It gathers situations that justify a prompt consultation.
Causes and risk factors
The disease is caused by a parasitic mite, Sarcoptes scabiei, which settles in the superficial layers of the skin. Each animal species has a slightly adapted variety of mite, but cross-contamination between species is possible.
Animals living in communities, such as shelters or breeders, are more exposed due to frequent contact. A weakened immune system, malnutrition or an unsanitary environment also increase the risk of infestation. Young animals and stray individuals are particularly vulnerable.
Transmission
Transmission occurs mainly by direct contact between an infested animal and a healthy animal. It can also occur indirectly through contaminated objects such as blankets, cages or brushes. Humans can be temporarily infected through contact with a sick animal.
Diagnosis and care
Diagnosis is the veterinarian's responsibility, based on clinical examination and laboratory tests. Care is decided case by case.
If your pet has persistent itching or skin lesions, it is important to consult a veterinarian quickly. Only a professional can confirm the diagnosis and offer appropriate treatment. Avoid any prolonged contact while waiting for the consultation, especially with children.
Prevention
It is recommended to avoid contact with stray animals or those whose health status is unknown. Maintaining a clean environment and limiting overcrowding in breeding areas helps reduce risks. Regular veterinary monitoring allows any skin problems to be quickly detected.
