Great for chewers!
Size: Large, Color: Ball-Blue
We have a super high energy one year old pup who destroys practically every toy she gets. This one is excellent! It makes a fun but not annoying sound and she hasn’t been able to destroy it yet. The test hole is a fun addition to keep her busy.

My Dog Loved It—Until It Stopped Working
Size: Large, Color: Ball-Red
I purchased this treat-dispensing dog toy for my German Shepherd, and for the first couple of days it worked exactly as advertised. When rolled or tossed, it made an engaging sound that immediately caught my dog’s attention and encouraged him to interact with the toy to get the treats out. He absolutely loved it.
Unfortunately, after only a few days, the sound feature stopped working. Then it mysteriously started working again for a short period, so I thought the issue had resolved itself. However, it has now stopped completely. No matter how much I shake, roll, or toss the toy, it no longer makes any sound.
I went out of town and didn’t realize the return window had passed while I was gone. By the time I returned, the return deadline had already expired, which was disappointing because I would have returned it when the problem first appeared.
Based on my experience, I cannot recommend purchasing this toy. While many of the reviews seem positive, perhaps I received a defective unit. It’s disappointing that it stopped functioning properly after barely a month of use.
That said, my dog genuinely enjoyed it when it was working, and I would appreciate it if the manufacturer would stand behind their product and offer a replacement as a courtesy. I would be happy to return the defective toy. If a replacement performed as intended, I would gladly reconsider my opinion.
For now, however, I am very disappointed with the functionality and reliability of this product.
