I have discovered today that Maddie, 6 year old PWC, has an affinity for the small dumbbell weights that we use here in the house for our arms (small 1-5lbs) and likes to drag them around.

So, I think maybe she'd enjoy that part of obedience is it that they have to go and retrieve the little dumbbells or whatever they are called things. 

Do people just make these out of wood or buy them? The nice plastic one's I've found for $10. Ideas?
