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 intense itching and significant skin lesions.
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 mite variety, but cross-species contamination is possible.
Animals living in groups, such as shelters or farms, 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.
Commonly observed signs
These signs are neither exhaustive nor specific. Only a veterinarian can establish a diagnosis.
The main signs are intense itching, often accompanied by redness, crusts, and hair loss, particularly on the ears, elbows, and belly. The skin may thicken and become rough over time. The animal often scratches to the point of self-injury.
When to consult without delay
This list does not replace veterinary advice. It gathers situations that justify a prompt consultation.
Transmission
Transmission mainly occurs through direct contact between an infested animal and a healthy one. It can also occur indirectly via 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 shows persistent itching or skin lesions, it is important to consult a veterinarian promptly. Only a professional can confirm the diagnosis and offer appropriate care. Avoid prolonged contact while waiting for the consultation, especially with children.
Prevention
It is recommended to avoid contact with stray animals or those of unknown health status. Maintaining a clean environment and limiting overcrowding in breeding facilities helps reduce risks. Regular veterinary check-ups help detect any skin problem early.
