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, I’d say it is ok to entertain very small puppies or dogs that don’t 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.

Very sturdy products esp for my big chewers
Color: All-Around Dog Puzzle Toys, Color: All-Around Dog Puzzle Toys
My dogs loved these, loved the lick pads as they have suctions, we personally use it for when we are bathing since my dogs hate baths, we just stick it onto the wall. The puzzles were fun which kept them entertained, the balls that had we were able to put treats in them, my dog loved it more as a ball as they are very ball driven. I bought this weeks ago and it’s extremely sturdy. Also easy to clean.
