A fun interactive puzzle your dog will enjoy!
Color: Green
It's a fun interactive puzzle for your pet. I have a mini cockapoo and he mastered finding the treats on the first try. Then I made it more challenging for my dog and it took awhile for him to master it. My dog never got bored or gave in. He seemed to like the challenge of finding all his treats. Fun and challenging puzzle!

Great teeth cleaning toy
Style: Gator, Size: Large (Pack of 1)
I bought this for my pit bull. He is 75-80lbs. They didn't have an option for his weight, so I got the alligator for up to 35lbs. He has already chewed the alligator's face off. Now it is just an analgator. lol I do monitor him the whole time since he is over the weight limit of this chew toy. The body of the alligator has proven to be better suited for my pit bull's chewing than the face part. I bought an Arm & Hammer yellow bone chew toy for teeth cleaning a while back. It was the BEST THING EVER for my pit bull to chew on. He destroys every toy in a matter of minutes. That yellow bone lasted forever and he chewed on it daily and consistently throughout the day. I haven't been able to find another one like it, so I decided to get this alligator despite it not being for his size. It still seems durable and I think would last longer with a dog under 35lbs. I give it 5 stars bc it is a well-liked chew toy in my house with the dogs I have that like to chew. It seems well-made and great for cleaning teeth.

Great for aggressive chewers
Style: Gorilla, Size: Small (Pack of 1)
My little Corgi is an aggressive chewer. She has destroyed quite a few toys that were advertised for chewers. When I received this toy I had little confidence but it has lasted unscathed. Aside from being sturdy it also bounces so we play ball with it. It is one of her favorite toys.

Strong and Great for Treats, but Heavier Than Expected
Style: Gorilla, Size: Small (Pack of 1), Style: Gorilla, Size: Small (Pack of 1)
This is a very durable and well-made chew toy with good overall quality. The material is thick rubber and holds up well to chewing. It also works very well for holding treats, which stay in place securely. The main drawback is the weight. My dog is about 30 pounds, and even though this is a smaller version, it is still fairly heavy. She tends to use it mainly to get the treats out and then loses interest afterward. What I like: Very durable material Works great for holding treats Good bounce and quality construction Cute design Things to be aware of: Heavier than expected Some treats may be difficult to insert Dogs may lose interest once treats are gone Overall: This is a solid treat-based toy that is built well, but the weight may limit how much some dogs interact with it beyond treat use.
