Fun little ball!
Fun little ball! Glad I got the football version the regular ball would be a choking hazard for my Great Dane. The ball rolls and shakes on the floor which at first was scary, but now she loves it! She nudges it all over the floor to keep it moving, keeping her entertained for a bit.

Won't hold charge
Unfortunately the toy would not hold charge. I charged it for couple hours and it wouldn't turn on. I tired a different charger to be safe and still nothing. Was hoping to share this exciting toy with my pup, guess I'll keep looking for alternative.

Luxury Dog, Luxury Toy”
“ I previously tried another toy, but its outer layer peeled off easily and even caused issues .This ball, however, is different. Even though my little dog chews on it, the ball recovers easily and causes no damage. It even gives a gentle workout for my pup’s gums and teeth. Maybe because my dog is small, it seems to restore well and is a perfect fit!
At first, I saw this advertised mostly for larger dogs. However, even though my pup is really small, they have no trouble playing with it and enjoy it just as much!

Dog loves it; but some poor construction
My small dog instantly loved this toy! I like the squeaker, bounciness, and options for different kinds of movement in the interactive play. It also recharges fast.
However, I have two downsides:
While my dog isn’t a big chewer, he got through this in a couple weeks. So we are on our second shell. That’s a nice option to be able to order just the shell.
Second, both shells have the same issue: they won’t stay screwed shut. The second shell is worse at this than the first. Once unscrewed, the interactive/mechanism piece will fall out and chocks be a choking hazard. It also frustrates my dog and he just barks at it until I fix it. With the new shell I think I had to fix it 5 times in the first 10 minutes of play.
Overall, it’s a fun toy and we’ll keep playing on!

Durable
Omg my dog loves this. The rubber is so durable my 2 yo aussie hasnt torn it up yet. I bought a cheap one from temu before and it took only 2 mins for my dog to tear it up it was complete waste of money. I love the football shape becahse it bounces unpredictably. I lile this to exhaust and exercise my aussie. This has become his favorite toy ever. It charges fast too. When im feeling lazy this is good way to exercise my dog and enrich him. I also teach him commands using this ball as his treat or reinforcement. Definitely worth every penny
