Just bought my second one for my German shepherd. 1st one I bought a year ago. She managed to pop it within a few days. She still was able to play with it by grabbing ahold of the straps. Takes it everywhere. We call it her tether ball. Should've seen her when we got the new one out of the box. Hasn't left it alone since.

Keeps him busy. Puppy proof

Size: 6 Inch, Color: Independence Day

Thankfully I bought 2. One of the pumps broke as I was trying to blow up. That is the reason i did not give then 5 stats. This is a great toy for my puppy. Keeps him entertained and is pretty sturdy.

Great for dog self play

Size: 6 Inch, Color: Red, Size: 6 Inch, Color: Red

So much fun for my puppy. Easy to grab and throw for him to play alone. Durable for a medium dog. This is his favorite toy. I also bought one for my friends cattle dog puppy who went bonkers with it. Yet her dog liked to chew the tags off. So I wouldn’t recommend for chewers.
