Not the Fetch-Fest I Hoped For
Color: Orange
I had high hopes for the PetDroid Interactive Dog Ball, especially with the newly upgraded features and promises of durable, motion-activated fun. Unfortunately, it didn’t quite live up to expectations for my furry friend. Here’s why I’m giving it 2 stars.
Promising Features, Lackluster Results
The idea behind this toy is fantastic: a durable, motion-activated ball that would entertain my dog without much effort on my part. The ball is supposed to roll around on its own, keeping my dog engaged and active. However, in practice, it just didn’t capture my dog’s interest.
Durability
I will give credit where it’s due: the ball is well-made and seems durable. It can withstand some rough handling, which is great for more aggressive chewers. Unfortunately, durability doesn’t mean much if your dog won’t play with it in the first place.
Motion Activation
The motion activation feature is hit or miss. While the ball does move around as advertised, it didn’t seem to move in a way that intrigued my dog. He gave it a sniff, watched it for a minute, and then walked away, unimpressed. I tried multiple times to get him interested, but he simply wasn’t having it.
Lack of Engagement
The biggest issue is that the ball just didn’t engage my dog at all. It might be more suitable for a different personality type or breed, but for my pooch, it was a total flop. He’s usually quite playful and curious, so I was surprised by his lack of interest.
Final Thoughts
Overall, the PetDroid Interactive Dog Ball might work for some dogs, but it was a miss for mine. If your dog is easily entertained by automated toys, it might be worth a try. However, based on my experience, I can’t wholeheartedly recommend it.
Pros:
Durable construction
Motion-activated as advertised
Cons:
Did not engage my dog
Motion activation wasn’t intriguing enough
Might be more suitable for specific dog types or personalities
If you decide to give it a shot, just be prepared for the possibility that your dog might not find it as entertaining as you hope. For us, it’s back to the drawing board for a more engaging toy.

Pup Loves It, Some Other Notes
Color: Orange
We've had this for about six months and my 75 lb, 14-month-old German Shepherd pup LOVES IT. Her favorite is "Crazy Bouncing Mode." In fact, she doesn't care much for the normal mode. She chews it a lot - even drops it in her water bowl at times - and it's still going strong.
This is a great purchase. It's nice hands-off entertainment.
Do know that it is heavy compared to a normal ball - if your pup likes dropping it on the ground like mine does, it will land with a hard "thud," even with the included sleeve. Hopefully you don't have downstairs neighbors.
Also know that the cover that goes over the charging port is removable and your dog may choke on it if they chew it in just the right manner. Definitely only let the pup play with it while supervised.
All in all, great toy.
