Every time someone brings a box or bag into my home, Max & Ben have to investigate. They will crawl into purses, coats, boxes, plastic or paper bags..it's all good. I have boxes strategically placed all around the house for Max. Many of my friends have dogs so when they visit us Max likes to have a few "retreats" out of the dog's range. Ben is a little different, he likes to play with the dogs. He is absolutely fearless.
