Outward Hound Dog Worker Green Interactive Treat Puzzle Dog Toy - Level 3 Mint Color

She had an easier version which was too easy for her. This one works out great and the level of difficulty can be adjusted. The only downside is the size. It's bigger and heavier.

Great quality and made out of very nice material. You can make it easier by removing the middle part. My dogs love it.

My 14 y.o. Dachshund mix loves it! Trying to incorporate more toys for keeping her brain working. She likes to paw at it as well as noes it. Very sturdy, east to clean. I only put try kibble or treats in it. It does not seem to hold onto smell. She has never broken a nail or hurt on nose on it so it seems soft enough, no hard edges. Great for dinner activity!

1) Product specification. Bought the green, circular toy with sliding cups and fishtails and a rotating central disc to cover the holes. Packaging says that you can lock the disc with the fishtails, but... you can't - it still spins freely with the fishtails in any position - but you can lock it if you leave a cup inside the one notch on the disc. So maybe that's what they meant, otherwise, the product isn't being manufactured to proper specifications! 2) Robustness. Dog is a border collie, so I bought this one even though we haven't tried any of the other puzzles, because reviews said collies solved those within minutes (which I'd expect... they're very clever dogs). Possibly I over-estimated his skill, but he isn't stupid, he just knows that if I let him, he could lever the central disc off with his teeth and get at the treats that way... So you definitely should not leave your dog alone with this puzzle for even a second! Also it wouldn't be great as a training tool, because if your dog isn't already obedient to being called off, it will wreck it within seconds. But it's a nice little diversion. 3) Treat extraction. I used very small treats at first (because I don't want to overfeed him) but he discovered immediately that he can curl his tongue right under the edge of the disc and extract them that way, which would be the same for peanut butter, so I advise that it works better with larger treats! Also don't use little flat disc treats because they can get stuck in the groove that runs around below the disc and require extraction with a spoon handle. 4) Puzzle solution. Putting treats under the cups so they have to be slid over the holes works well, although I'm not sure if he's actually worked that out or it just happens naturally as he snuffles for the treats. The fishtails are free-spinning at all points but do need to be moved out of the way to uncover the outer treat holes, so they add a little extra challenge. Turning the central disc is so far proving a major challenge. It's a little stiff, and he wants to use his nose and tongue rather than his paws, so I think that might be causing some of the trouble, but he also clearly doesn't understand what he has to do - yet. I'm hopeful we'll get there eventually though, and at least it means he hasn't solved the whole puzzle at once! Overall, the puzzle is well made (apart from the odd inability to lock the central wheel the way it describes) and sturdy, except that the average dog's jaws can get through marrowbones, so 'sturdy' does not equate to 'indestructible' and (I repeat) you really must not leave your dog alone with this, like the packaging warns. It's a bit of a faff to wash clean, because of all the sliding parts, but it does rinse and drain well. Dog loves it - well, he loves finding the treats - to be honest I think he'd have just as much fun, and use about as much brainpower, hunting for treats under upturned cups like in the 'find the lady' street hustler trick, so whether we've wasted our money remains to be seen; if he can just work out what's required to move that central wheel! (To be fair to my dog, he is medicated for epilepsy and probably stoned out of his gourd half the time, which doesn't help.) So it's not a terrible product... but I'm less satisfied with it than I'd hoped. I think I should probably use it daily to help him learn. You could use it more often if your dog eats kibble (just use some of his daily food ration) but mine has rice for dietary purposes so kibble is out.

Good toy, made with recycled materials too.
