Our dog Tigger has LOTS of energy. 😅 Even with my husband taking him to run alongside his bike around the block three times the other day, Tigger wasn’t even panting by the end. 🤣 I was talking to a new friend who mentioned more mental stimulation could help. Last Tuesday evening, he learned “give paw” within about 15 minutes. Hmm he’s a SMART pup. 🤔 Bonus…teaching him that seemed to really tire him out. From that point, I looked up dog mental stimulation toys here on Amazon and bought three puzzle feeders—this one is one of them. They’ve been amazing!! Tigger has been slowly catching onto how to get the food, which stops him from eating so dang fast AND also exercises his canine brain. ⭐️⭐️⭐️⭐️⭐️ I HIGHLY recommend something like this if you have dogs that have boundless energy or just seem like no amount of exercising helps calm them down.

Works well!

Fun for dogs! Only silly thing is it moves around on the floor a little bit, but overall works good! My lab loves it

Great for busy pups and smart dogs!

This keeps my puppy blue heeler busy and happy. Easy to fill and wash. I put her puppy food in it and put it in her crate to play with. The kibble fits perfectly in each little hiding place. After a month of fun it has not broken or malfunctioned.

Great treat

Gave this to my friend’s dog, and they took a video when they put it down! The dog immediately found one of the treats and kept looking for the other treat and eventually found it this dog loved it!
