One of the questions on my new-client questionnaire is "Does your dog attempt to dart though an open door?" I’m always careful when entering a client's home, but if the answer to that question is "yes," then careful doesn't cut it. I need to be vigilant. It’s stressful; especially since the same dogs usually try to do the same thing when the door to the Element opens. This is the first thing I teach every single new dog - they must wait until I tell them it's ok to jump out. Otherwise they would be jumping out at every new pick up and drop off spot. But what happens when it's not me or the client coming through the front door, but rather a cleaning service or a contractor? Their job isn't to mind the dog. I arrived at client's home one day, a couple of years ago and the contractor told me the dog ran out as soon as he arrived, and that he had to chase him 3 blocks to the park. This story ended "well," but they don't all, sadly.
