Fun activity for my pup
Color: Navy Blue
My 6 month old Labrador dog has so much fun with this! When he sees me getting it ready he gets excited.
It’s super easy to use and clean! The price is the best! Quality is great. No noise and fun for my dog.

Great Puzzle, My Dog Loves It!
Color: Navy Blue
It’s perfect! My dog loves it and i’m very satisfied with this purchase. The outside of the box did come sticky, which was kind of weird. Overall it’s great!

The outer part of puzzle is awesome! The inner...not so much.
Color: Navy Blue, Color: Navy Blue
My doggo Josie is a pretty smart dog. She can give you the most pitiful look (like in the pic) where you're giving her most of your lunch. She can hide your socks in another dimension! She can sit, shake and yes when Alexa plays "Turn around" by Bonnie Tyler...she will do it. I like to challenge her with a puzzle. She figured out the outter part of the puzzle within minutes but I was disappointed she couldn't figure out the inner part of the puzzle. Then I figured out why. The inside puzzle is very hard to push around. She gets frustrated that it won't open or move around very well. I let her do the outer puzzle for treats but I no longer put treats in the inner part. I want her to be entertained...not frustrated. I'll keep it for a bit and then pass it on to a dog shelter.

Great fun
Color: Navy Blue
Great fun to watch my dog learn how to get his treats. Slows him down so they last longer. He’s almost ready for level 3.
