Not as Smart or Interactive as You Think it Will Be
Color: Blue
This is an honest review from a schnauzer owner who has has wanted this cheerble ball for their dog for more than one year. I finally bougI finally bought this toy and both me and my dog are disappointed. The settings are...i would say dog friendly as I'd assumed a dog ball would be. What I mean by that is, for example: the calm play setting is muuch too calm. Super light puffs of energy, like a battery is dying. And the playful setting is scary, alarmingly so. The intervals in between are too long. The ball does not bounce. So they just have settings all wrong. The size is good for a large dog only. Do not buy if you have a small to medium dog. I even think the material is okay. I've only had it for a few days so I can't even speak to how the material holds up. Really hoping to love this ball for my dog. It was not the distraction I was hoping it would be so I could work from home while my dog had fun. I'm hoping this can help someone else who's been pining over it. Essentially, it's a $35-$50 well made weighted ball that moves occasionally.

Perfect Size for Tiny Dogs
Style: 14" Length Sport Launcher, Style: 14" Length Sport Launcher
Excellent size for tiny dogs who can only manage the tiny tennis balls. The launcher is easy to use, even for my 8 year old. It’s pretty much revolutionized ball time for the dogs and the kids - they actually like taking him out to play fetch now. It’s super light but still lets you toss the balls a lot farther than just throwing it. Great value for your money and it’s helps strong for weeks of repeated used, super durable.

Great for small dog fetch
Style: 14" Length Sport Launcher
We love this for keeping our hands clean and saving our shoulders while playing fetch. Not sure why this size is so incredibly difficult to find (not in any stores in our area). It fits both the small rubber and tennis ball types. We have a 15lb rat terrier, and he loves it.

Ball is very small
Style: 14" Length Sport Launcher
It says it’s for small dogs up to 15LB. My doggie is 15 LB and this is way small. It’s a tiny ball. If your dog is 12LB to 20LB I would get the next size up to small.
