Mange is a skin disease caused by parasitic mites with symptoms including severe itching, hair loss and the formation of scabs and lesions.

When Animal Aid found the dog at the roadside it appeared completely bald, resembling worn leather.

The organisation has complied a touching video of the dog's recovery.

It was too exhausted to eat on the first day and had evidently become used to being devoid of company.

However, by the 10th day of intensive treatment all of its skin had healed and after two months it looked like a regular, happy dog in what is a testament to those that took the animal in and cared for it.
