It’s a lot smaller than pictured and I have the same dog type as was depicted in the one of the pictures. The dog like it so I guess that’s good. I will not be playing tug of war with him using this. I like my fingers thank you very much. I would say it durable. He destroys most toys in minutes. He did destroy the squeaky part in about 10 minutes so bonus points for that.
