If a dog of yours scratches or nips at you and you don't see any signs of bleeding, cuts, or wounds, the risk of rabies is among the lowest. Rabies is mostly an infection through saliva, hence, when there is no open wound, the chances are minimal. Watch out for any strange signs such as a fever, headache, or tingling in the area near the scratch. In the event, you spot something peculiar, it's best to get checked out by a doctor anyway. But for now, you should be just fine. Rinse the wound under running water and lather it with soap to disinfect it.

It is crucial if you have a rash on your penis to consult a dermatologist or a doctor who specializes in the urinary tract as soon as possible. It might turn out to be an ingrown hair but you might be prone to a sexually transmitted disease.
