I have worked at an all animal veterinarian clinic where my main job was to walk dogs, check in them, administer foods, etc.. I currently work at an all cat clinic. However, I own a 120+ lbs English mastiff and an rott weiler/bull mastiff mix, so I am comfortable with dogs of all sizes. I'm currently a college student working her way through school to become a veterinarian of sorts. My schedule does not change at all.
