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.

Pup loves this!
Size: 6 Inch, Color: Red
This soccer ball is so cute. My dog loves to play with these. The straps are durable, easy to pump up (they come with a pump), good value for the money since they tend to last awhile, at least for us. The straps are durable but could be an issue if your dog is an aggressive chewer. They stay pumped up for quite awhile and just need to be topped off once in awhile to keep the bounce there. We keep them outside even in the winter and they do just fine. HIghly recommend as a good play toy.

Great Ball
Size: 6 Inch, Color: Red
Our Little Goldendoodle Loves this ball & I like that it has so many straps to grab so I'm not getting the slimy part. It does not come already inflated so make sure you or a neighbor have an air compressor to blow it up because even though it came with a little pump I can't imagine how many weeks I'd have been pumping that without noticing any difference.
