From the excellent picture you have provided it looks like Winstyn may have moist dermatitis, or a "hot spot". Unfortunately, hot spots often require a trip to the vet for clipping of the area, cleaning, and prescription of a healing spray / ointment with antibiotics and a steroid. All of these interventions will help the area heal quickly, and minimise the level of discomfort that Winstyn has to experience. Due to the location of the sore it will particularly difficult to treat at home. In the meantime you can help Winstyn by; Placing a an e-collar to prevent him biting or attracting at the sore and making it worse Attempt to air out the area as much as possible to help it dry out. This is key to healing. Do not attempt any medications at home as they can cause pain and in some cases delay healing. I hope this is a helpful answer and that Winstyn feels better soon. Warmest regards to you both.

    This looks really infected. It may be a hotspot or an allergic dermatitis that has become infected. You should really has this seen by a vet as it will need prescription medication to treat such as topical cream and systemic antibiotics. Antinflammatories may also be required.
