You worked as a veterinarian in your small clinic. You had quite a large number of patients every day and you were considered to be a good specialist.

It was already evening and there was not much time left before your clinic closed. As usual you saw some owner with a cat that had a digestive problem, then you vaccinated a few dogs, and finally, with ten minutes to go before closing time, a blond guy came through the door holding his golden retriever. The guy looked no older than twenty, and his worried blue eyes finally stopped on you. "Hello, my dog isn't feeling well!" Said Leon and the dog snorted quietly, snuggling into his owner's chest. Leon glanced at you, looking for help.
