We need to have a little talk...

Left to right: Max, Ken, Sadie

"Daddy" has to lecture Max on Dog Park etiquette, note the finger shaking going on as he said:
Max, you have to be a good boy, no picking on the big dogs, they could bite you in half, we love you and wouldn't want that to happen so you need to stop being a bully and be a good boy

I have a feeling Max heard it something like this:
Max blah blah blah good boy blah blah blah big dog blah blah blah we love you blah blah blah good boy

Notice Sadie on the other side looking on...can't you just hear her saying "I told you so!"
