Hi all, I'm in need of a little help. Quite some time ago somebody posted a link to a list of mentally stimulating exercises for your dog. It consisted of 20 exercises, one if which was being in a down stay for about 30 minutes daily. Sorry for being vague, but this is the only thing I remember. I've looked around the boards to see if I could find it, but I didn't have any luck. Thanks in advance!
