This has become one of my puppy's favorite boy's. He is so smart and flustered through the beginning interactive toys quick. I got him this one next. The design is good. He did get through some ok, but got frustrated early with the harder ones. Started flipping and chewing it. It wasnt easy to chew through but did snap a few hinges. Stubborn dog, but still enjoying it. . It moves easily and does stimulate him to think. Great toy especially for smart dogs. Mine is just too impatient and growls at it.

Great toy

Color: Yellow

My dog loved this! Kept him entertained for some time. Only problem I had was trying to unscrew the ends after he was done so I could clean it (my dog slobers a lot lol). With him playing and trying to chew it made the ends tighten more. But over all great toy!

Fun toy!

Color: Yellow

It was funny to see how my cat figured out how to roll the toy to get treats out. Great idea that makes your pet work a little for a reward.

Cool toy

Color: Yellow

Its pretty cool & drops a piece of kibble about every 5'. It rolls easily on my wood floors & has rubber type ends so it doesn't bang up my wood floors. Only downside is my golden retriever doesn't get how to use it yet. Still working on it.
