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.

Our German Sheppard loves these
Size: Medium
These cost a bit more than tennis balls, but they are so much nicer and longer lasting. For starters, they stay cleaner than tennis balls because they’re smooth rubber. Dirt won’t build up on them and if anything does stick, like grass or soil, it falls off once the dog slobber dries. They’re also thick, so they don’t fall apart or blow out like a normal tennis ball does in our dog’s jaws after 30 seconds. Our GS chomps on these like crazy and the only damage they’ve suffered is a crack that developed from the edge of the hole, but the crack is growing very slowly and none of these balls have totally failed yet. The balls do whistle when thrown ant high speed and that may help a dog track and locate it, but I’m not sure. Our neighbors hear the whistling too so it’s far from silent. Lastly the orange ball is easy to locate out in our yard, but the dark blue practically disappears.

Great for smaller dogs
Size: Small
These two balls are perfect for the smaller mouthed dog that loves to play fetch.
These balls are not only super durable (lots of teeth biting), but float in the baby pool we use for our miniature dachshunds.
The value here is much better than you’d find anywhere else. The noise, if bitten hard enough, was “low” at best. Easy to spot/find if overthrown. Will definitely buy again once these are in bad repair; so far, so good-love these for my fur babies!

My dogs favorite balls
Size: Medium
These are great for my dog who always has to have a ball in her mouth. Not too hard so I don't have to worry about her teeth. They last for ever. They do lose their shape a little over time (like I said, she always has a ball in her mouth) they become a little oval in shape. They still bounce, she still chases it and she still chews on it so I don't think she notices or cares. I've gotten her a bag full of these over time and I have only seen one that she chewed a chunk out.
