I like this stick!
Dogs attach themselves to the strangest of things and get great value from them. When it's time to go home Rosie will usually drop any such item and leave it on command. Occasionally she finds something that she likes a lot and will walk directly behind me taking care to move sideways out of view if I look over my shoulder in the hope that I will not notice that she still has the object in her mouth. This has been tested on a number of occasions. Where did she learn that?
