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! Itβs 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 set of dog toys. Lots of variety!
Color: All-Around Dog Puzzle Toys
Great variety of different dog toys. Keeps my dog entertained for a while! She loves the round one with sliding doors. The rubber balls are well made and provide a longer time of play.

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.

Not made to last..
Color: All-Around Dog Puzzle Toys
I got this kit to help entertain our litter of Golden Retrievers as they got bigger, waiting to go to their forever homes. The quality was pretty good. It worked great when they were small, but as they got bigger and stronger, they were able to chew up and destroy the balls, especially the hollow ones. The balls that hold the treats in between the layers help up better, but after 3-4 months I took them away because they started showing teeth marks. The lick pads have lasted, we still have them 6 months later, and the puzzle thing was ok until about a month ago when the puppy we kept learned to pop the sliders off instead of push them to the side. All in all, Iβd say it is ok to entertain very small puppies or dogs that donβt chew a lot, but definitely under supervision. Definitely not for aggressive chewers or larger dogs, as the balls are all very small.

Fun set
Color: All-Around Dog Puzzle Toys
Super cute and dog feeding kit with lots of options at a great price. The balls are a little on the flimsy side, but for the price the set is hard to beat. I have a 12 pound dachshund who is a fast eater, but also loves a good challenge. While the toy is not difficult for her to figure out (she is a little to smart for her own good) it does at least slow her down enough that she chews her food some. The sliders on the feeder move around easily which make it easy to clean and refill, but also make it a lot easier for her to get to the food. It is probably comparable to a level one difficulty for anyone who has tried the Outward Hound food toy games.
