 Your goal is to make that dog or cat feel as comfortable as you possibly can. So when a dog first comes into a new environment, what I do and what I would recommend for the years I was working specifically with people is what I would do is I would say, listen, even when you're home with the dog, go into another room for two minutes and come back in. Don't make a big deal out of leaving. You can say goodbye and hello, but very softly. And again, once the dog realizes that when you leave in a short period of time, you're coming back, what a great thing.
