Walks with my dog are for HER enjoyment.  I love the walks, but my agenda stays at home.  So we “go for a bumble” (Helen Philips of Clicker Gun Dog Centre), just wandering around with no real goal in mind.  As long as she does not pull (or go somewhere unsafe) she is free to sniff and wander to her nose and brain’s content.  Most days it is a good combination of walking and sniffing.  One day we we spent the whole hour in the parking lot of our local park.  She loved it and was exhausted when we were done.
