Playing Hard, Laughing Hard

The puppies are really active now, playing and interacting with one another and for that matter us too. We can tap on the side of the whelping box and they come running (ok not exactly running but close to it). Doug and I find ourselves sitting at the edge of the whelping box just laughing at them. I guess playing hard makes them giggle more (if dogs do that) but maybe a picture is worth a thousand words.
