This is a great toy for dogs. You can put their food in it and have them work to get to all of it. You can also plug the hole at the bottom and fill it with beef stock and freeze it, and the dog will have a frozen treat to play with when it's hot. You can also leave a hard to reach treat in it, and he will try for a long time to get to it without being bored. It's very durable, and since they reduced their price it is not expensive at all for the quality. My dog does not like the imitation brands though.
