Dog Puzzle Toys for Boredom, Chew Teething and Treat Dispensing for Smart Medium to Large Dogs - IQ Mental Enrichment Toys (10 Pieces)

This is a great toy! My poodles LOVE it! There are different levels of difficulty, so that's important to know when you're putting in the treats and assembling it. The dogs just LOVE watching me put the treats in, as they sit there, watching and waiting. I have two dogs, and they are at different levels. I like that because my male poodle needs a high level of difficulty, and my female will give up if a puzzle is too hard. I bought the 10-piece set and when I put it together I give my male 6 pieces, and my female 4 pieces. Then they work on them together side-by-side. The best thing I like about this toy is since it's also a chew toy, it takes them a long time to "solve" it, but they don't mind because they're also playing with it. I buy a LOT of dog toys and puzzles, and this one is at the top of my list!
