Ok I don't understand the problem here. I have lived around animals my whole life. If it was in the 80's or 90's out yeah I might see a issue, but then 15 mins be real folks 20 degrees that is below freezing last time I looked.

So before we get too pious how many of you own dogs, and how many of you take your dog with you, or just leave them cooped up in the house or backyard. That is the cruel part. This gentleman likes to take his dog with him, he has my vote, must be a good owner and a good friend.

Now for the lady at the Home Depot, there may have been issues there before, after you explained it to her though she should have backed down. Common sense should have a place somewhere in the whole situation.
