When we go for a Walk at muddy-grass-big-fields-and-then-lake, we stop to do a Trick.
This Trick is very simple. Right now Lake is very full. There are people-benches that normally are on dry land, but right now these people-benches are out in the water. This is because Lake is too full.
Here is the trick. Our person wades out to a bench. She stands on it. We wade out too, in the cold, over-full lake. We put our paws up on the back of the bench. We get treats.
But here is the trick. Our person tells us that this is Fun, and Training. But we know the truth! The truth is this: After our walk through muddy-grass-big-fields, we are muddy-dogs. By getting us to wade into the Lake, our person is washing off all of our mud!
She thinks she is very clever. She thinks she has tricked us. But we know the truth!
So why do we do it? Why do we let her wash off all of our lovely, stinky, sticky mud? Because there is Cheese involved, of course!!
