Hi. This appears to be a hot spot on him. This is basically an area of a moist dermatitis , or skin infection. They are usually secondary to allergies of some type. They are treated at the veterinarian by clipping the area, cleaning it with medicated cleaner, and then antibiotics and antiinflammtories. I'd call your veterinarian in the morning for an appointment

    This looks like a hotspot (moist dermatitis). You would need to have him seen by your veterinarian for confirmation. Treatment for hotspots typically involves clipping the area and scrubbing it lightly. Topical and/or systemic antibiotics may be indicated. Your vet may also dispense a steroid for inflammation and itching. You will need to place an e-collar (cone) on Ozzy to prevent scratching or rubbing until the area has healed.
