My male dobermann loved the training cube tug as soon as I showed it to him. It's heavy enough to throw and strong enough for a game of tug. Because it's soft he can really clamp down on it without fear of it damaging his teeth and the stitching has held up. My only slight gripe is that they are quite large so you need big pockets (or a bag) as I have absolutely no hope of carrying it without my dog trying to steal it! Highly recommended.
