i bought Chelsey a tiny kong, its really small so she can handle it on her own, its handy for her to put her little sharp puppy teeth in instead of in my fingers
i also put some "fresh meat for dogs" in mixed with her dry food, it keeps her occupied for some time while i do my work around here, my lab has the giant kong and loves it, the kongtoy's also make good icecreams for summer time, fill them with yoghurt and fresh fruit and pop it in the freezer for a few hours
