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.

Toy bouncy balls for puppy
Color: Yellow/Blue, Size: 2 in
My puppy loves, loves, loves these balls. We can even put treats or dry dog food in the open grooves to add in the playtime. These small balls are the perfect size for our Yorkie. He can easily grab them in his mouth to retrieve them and carry them to wherever he wants. He even likes rolling them around as he pushes them with his nose. Very entertaining toy for puppy and us.

Keeps our pups busy
Color: Blue/Green, Size: 2.75 in
Approx. the size of a tennis ball, perfect for our 2 doxies, keeps them happily occupied. Appear to be nice quality and will last a while.

A must have.
Color: Yellow/Blue, Size: 2 in
My dog loves these. They are pretty sturdy. He’s a big chewer and they have held up. I put treats in the cracks to keep him busy when we are away. For some reason, his favorite is the blue! Good value.

Great for cats too!
Color: Blue/Green, Size: 2 in
Love it, perfect for my cats. Keeps them busy and slows down treat time. 4 stars only because they don’t seem very durable for hard core chewers, one of them already showing signs of wear.
