My dog loves this
We have had approximately 6 of these, they get thrown in mud, puddles and the sea. They very quickly look a muddy brown and blends in to the surroundings, which means our dog has to search hard for them, which is great. Our only problem is they never last long enough. They only get used while on a walk, but still get chewed and ultimately fall apart. Even so, our dog absolutely loves this, I wish we could get one that lasts longer!
