Durable like a toy but it doesn't keep the dog occupied at all. I tried putting it in boiling water as some suggested to bring back its flavor but nothing.

I bought it for my 7-month-old Pitbull and many times he doesn't let go of it, the good thing is that it is durable and doesn't break, at least not quickly

I have bought it 4 times, they really like this game as it is also edible.

Tip: if you notice that they are losing interest, put it in boiling water for a while. This way it regains its scent
