Scabbing not caused by a wound, especially if it is bleeding (from scratching), is a sign of the mange and should be treated as soon as possible by a veterinarian. It can gradually spread across a dog's body and eventually kill it.

Your body creates scabs to protect the inside of the wound/sore from infection so it has time to heal
The healing time for dog scabs can vary depending on the size and severity of the wound. In general, small scabs may heal within a week or two, while larger or more severe scabs may take several weeks to fully heal. It is important to keep the wound clean and monitor it for signs of infection during the healing process. If you have concerns about your dog's scabs, it is best to consult with a veterinarian for proper treatment and care.
