Any quick suggestion, what would be this? And what needs to be done to treat it - the wound was powdery and broke off and the skin is visible this way.

This looks like an infection , you can use spray viv silky on the affected area but the infection is likely to spread and if you notice such leasions in other areas of Brunos body its better to get Kuddle veterinary consultation for further treatment.
