Yesterday evening I tool my 2 doxies over to my parents house for the first time. I have only had then for 1 year and they have not gotten to meet the "grandparents" until last night. So, we pull up to the house, which, like most homes, has a front door, lots of long windows, some short windows, etc. The dogs bound out of the car, and without waiting for me, run up to the front door. My parents had not come to the door, it was not open. Now, since the dogs have never been here, how do they know that is were we go in?? Have they evolved that far that they recognize that as being the entry point? I would love to hear what other dog lovers think!!
