Fantastic Mental Stimulation for My Dog!
Color: Higher Level-Navy A
I am absolutely loving the Dog Puzzle Toy! It’s such a great way to keep my dog mentally engaged and entertained. The concept is simple—just put treats into the puzzle slots—and it provides hours of fun as my dog works to figure out how to get to the treats. It’s amazing to see how much focus and problem-solving skills he’s using!
The toy is sturdy, and the slots are easy to fill. I love that it’s adjustable, so I can make it a bit more challenging as my dog gets better at it. It’s also made from durable, pet-safe material, which gives me peace of mind knowing it’s not only fun but also safe.
My dog seems to really enjoy it, and I can tell that it’s helping with his mental stimulation. It’s a great alternative to traditional chew toys, and I’ve noticed a positive difference in his behavior and energy level.
Pros:
Great mental stimulation for dogs
Easy to use—just add treats
Adjustable difficulty level
Durable and pet-safe material
Keeps dogs entertained for longer periods
Cons:
None so far!
This toy is perfect for keeping my dog entertained while giving his brain a workout. I highly recommend it for anyone looking to challenge their pet in a fun and rewarding way!

Please read!
Color: Higher Level-Navy A
The design is adorable and I love the little bones and paw prints they put on the tabs. They are easy to slide and the colors are bright and admirable. There is different difficulty levels. The yellow circles are more on the easy side. The red ones are a bit more harder if you have a more intelligent dog. The three white tabs in the middle move in a 360 circle, there is one missing so you can slide the red tab in to hide the treats. I use my dog's kibble as treats; the kibble pellets are 1cm in length and 1cm in width. I can fit about 2 pellets in each tab hole, there are 14 small holes which you can hide the treats in total.
Cleaning the puzzle
It depends if you wash it by hand or put it in the dishwasher. I do both but I prefer the dishwasher because it is a little hard to clean by hand since there is so many nooks and crannies on the toy. Of course, it is dishwasher safe and I recommend putting it in by itself because you don't want to cross-contaminate the dog slobber to be on your dishes. I wouldn't put crushed or wet dog food in it because it could get in the sliding rails and jam it up or get moldy. If you are going to dry the toy, open all the tabs so they are exposed. If you cannot, that's okay.
My dog's opinion
I have two dogs, a 2-year-old chocolate Labrador named Maggie and a 7-year-old labradoodle named Rufio, Maggie takes about 1 or 2 minutes to finish the puzzle because she is super energetic. Rufio takes 3 or 4 minutes because he is calmer; but sometimes I have to help him just a little bit. It is suitable for all dog ages and I recommend it if your dog (s) are annoying you. They both love it and I give it to them for mental stimulation and as a reward. The bottom has "non-slip pads", but if I'm being honest they actually don't work that well. My dogs just slide it around.

Great design!
Color: Higher Level-Navy A
This Joansan Dog Puzzle Toy is exactly what I was looking for. My little MinPin is a worker and he likes having a job to do. I purchased this to entertain him when rolling his treat ball all over the place isn't practical. This disc has a non slip bottom and it's actually fairly heavy. It doesn't slide easily. So my little worker usually ends up picking it up and transporting it to different locations throughout the house. Obviously, individual results will vary, depending on size, personality, and breed of the dog using it, but it's been great for my lil guy. He gets a little physical and mental exercise. It's sturdy enough to withstand his scratching and chewing. My big dog likes it too. The size is perfect for food oriented cats too. My cat is too lazy to work for his food though. So he wasn't interested in it.
