Nice but…
Color: Blue Green Orange
Nice but not very sturdy and it comes rolled up so it’s difficult to get it to lay down for your dog.

Both my dogs LOVE find the treat game time!
Color: Orange Red Blue, Color: Orange Red Blue
Both my dogs have loved this for years. Both senior dogs - great fun activity for them and they really hunt for all the treats we hide! My little one usually wins and takes over the game board then uses it as a lounger after :-) It’s very interactive with different ways to hide treats and challenge the dogs. We’ve had it awhile and it has stood up to many uses and washes. Very easy to store and simply roll out when it’s game time. Highly recommend!

Perfect for snuffle dogs
Color: Blue Green Orange
If your pup/dog snuffles EVERYTHING or has a demanding intellectual stimulation food regime they set themselves this is for you! I have to roll out the mat above the floor to situation treats, but once it hits the floor my puppy is preoccupied for hours. She has so much fun sniffing through every element to find her treats. While the mat is easy to use I recommend rolling it back up immediately once most treats have been found to avoid chewing on the actual mat pieces (this could present a durability issue as the fabric is chewable). I use different flavored and textured treats throughout the mat as well as her normal dog food to keep her interested. Definitely worth the money if you have a snufflopogus puppy like I do.

Durable and engaging!!!
Color: Blue Green Orange
This has been a game changer! My dog all of a sudden started gently chewing on a couple of my shoes while I was at work. I set this out right before I leave for work. My shoes have been safe ever since!!!

My dog LOVES this!
Color: Blue Green Orange
My dog LOVES this thing! It keeps her busy for a good 45 minutes if she gets distracted, we use it to hide her food because she swallows it whole when we feed her in a bowl. So this has slowed her eating wayyyy down and has helped immensely in keeping her occupied. The quality is nice, i love that it’s felt, BUT it seems like if she scratches at it enough, the strings of the fabric come out and feels fuzzy. I’m not sure how to describe it but it looks like it might experience some pretty bad ware and tear after a while. I love how easy it is to set up, and the variety of folds help the food get stuck so that my dog can sniff and dig her way around. Very nice toy set up!
