My dogs love them! And they are cheap. And they last a long time! But they smell like cow manure when the hounds chew on them. But that isn't the worse part. The dogs are not good about picking things up....AND...everyday...usually late at night when I get something to drink after bed time...or just at random...I end up stepping on one...or two of them. Let me tell you...you don't know pain until you have stepped on a half chewed cow hoof. Way worse than a Lego.
