This could very well be a fungal infection or a bacterial infection. Fungal infections start out as a round hairless lesion, that gets bigger in diameter and starts to eventually grow hair from the middle out, there can be several of those lesions confluencing, Fungal infections are contagious to people. Both a fungal and a bacterial infection need to be treated, There are antifungal/antibacterial shampoos and also oral medications which would need to be prescribed by a vet, I suggest you take Dymond in for an exam and treatment according to the diagnosis,
