I think this is a good way to find out what type of nylabone your pup prefers. The white one is hard, tan one is softer plastic, and the other is edible. My pup loved the edible one and the softer one but had no interest in the white one. Turns out she doesn't like hard chews-- which was reinforced by other toys discarded over the next year! She loves the tan softer one and still chews on it a year later. Granted she is small - 10 pound chihuahua mix - and not much of a hard chewer, so this has lasted her. If yours is larger or harder on chews, I'd doubt that they'd last so long. If you've got a new pup in your life, though, this starter pack is a good way to learn about their chewing preferences.
