Re:Why do dogs love...
WHY NOT or IT IS FUN
Dogs sense of smell is much more sensitive then a persons sense of smell. Dogs get a great deal of information about the world through their smellers (but I don't think they know how bad their farts smell, or they do, and they just enjoy the smell)lol That being said, watch your dog while walking, all of a sudden they will veer off with their nose to ground following another scent. Or think about hunting, tracking, or drug/bomb/cadaver sniffing dogs. They are trained to use their sense of smell.
So the dog nose out the window may just be a way of discovering/enjoying the world around them
Or, they just like the feel of the wind in their faces..
I do know that when we get with a mile of our property the dogs perk up, it is as if they know we are almost home.
