Sturdy, well made, puppy & senior dog approved
Color: Glow in the dark I, Size: Medium
Pet approved !!!! Our puppy immediately grabbed it by the straps and took off!! It is well made and has handled some serious chewing in the last 24 hours. We love the glow in the dark because puppy playtime does not stop when it gets dark out!! It came with a pump and was very easy to assemble and inflate. This toy would be great for a pet owner that struggles with grasp & grip strength, the straps are absolutely genius.

Fun, Durable Ball, But Straps Could Be Tougher
Color: Glow in the dark I, Size: Large
I bought the QDAN Glow in the Dark Dog Toys Soccer Ball for my German Shepherd, who absolutely loves it. The glow-in-the-dark feature is great for evening play, adding an extra layer of fun to our outdoor interactions. The ball itself has proven to be remarkably durable, standing up well to the rough play that comes with a large, active dog.
However, the straps did not fare as well. My GSD managed to bite through most of them relatively quickly. While this hasn’t stopped us from enjoying the ball, it does mean that some of the interactive potential of the toy is lost. The ball continues to be a hit on its own, thanks to its resilience and the glow feature that keeps my dog engaged.
If the straps were as durable as the ball itself, this would be a perfect outdoor toy for energetic dogs. As it stands, it’s still a good purchase for anyone looking for a sturdy, engaging toy for their pet, especially if nighttime play is a routine.

Perfect toy for an active dog!
Color: Large size (7.9")
My dog absolutely loves this ball with handles! It’s quickly become one of his favorite toys, and he gets excited every time we bring it out to play.
The vibrant colors are a huge plus—they make it super easy to spot in the grass, which saves a lot of time during outdoor play sessions. The handles are great for interactive play too, especially for tugging and tossing.
I’m really impressed with how well it’s holding up. Even with constant pulling, tugging, and rough use, it’s remained durable and hasn’t shown any signs of wearing out.
Overall, I’m very happy with this purchase—and if my dog could write reviews, it would definitely get his paw stamp of approval! 🐾
