Perfect All-in-One Pet Enrichment Set!
Color: All-Around Dog Puzzle Toys
This puzzle dog toy set is amazing! It’s the most thoughtful and efficient enrichment set I’ve ever used for my crew.
The lick mats are high-quality, durable, and the included cleaning brush makes cleanup effortless by reaching every groove. The spatula is perfectly designed to spread treats like peanut butter or yogurt evenly, saving time and preventing messes. These small details really set this set apart from others.
Beyond the lick mats, the set includes a puzzle feeder and three puzzle balls that keep my furry babies mentally stimulated and entertained. Each toy is durable, easy to use, and provides a great challenge for everyone. The variety in this set ensures there’s always something to engage my critters and meet their varying challenge level needs.
It’s clear this set was designed with both dogs and owners in mind, addressing common pain points like cleaning and mess-free prep. It’s perfect for smart dogs (and other critters!) and delivers great value for the price.
If you’re looking for interactive, mentally stimulating toys for your pet, this all-around set is a must-have. My crew love it, and so do I. Five stars!

Great set!
Color: All-Around Dog Puzzle Toys
This is a great set to entertain and beat your dog or puppies boredom! The material is natural so safe there! It’s also very durable ! The mats have suctions on bottom which is very smart ! The treat balls make a good toy even without treats in my experience. You also get a couple free gifts which was a nice surprise.

Great package of toys
Color: Curated Dog Puzzle Toys
We have a new rescue dog and she eats too fast so we got these to help slow her meals down, and to give her something to do during downtime. The balls are so fun for her, the puzzle one is cool but she knows how to get the food out now so it doesn't take her long to finish it. The lick pads are nice but I have to place them on a cookie sheet so it doesn't get our hardwood floors oily with peanut butter. I think thos whole bundle is a great value. Side note: do not leave your dog alone with these toys because they will chew them up easily. I take them away once the treats and food are gone.
