Best toy I've found in a long time!
Color: Purple, Size: Medium (Pack of 1)
I got the small Nobbly for my 3lb puppy, but it's too big for her (she loves the xs bouncy ball one anyway). So my 15yo standard poodle adopted it and loves it. It's really too small for him so I watch him and don't leave him unattended. He is so old with bad teeth, and the softness of the center is great for him. It is totally cleaning his teeth, I see white where I haven't for years. But ZERO bleeding which is awesome. It's easy for him to hold and difficult for him to get to the rings, they last plenty long. I will order this one for him in a larger size, probably the medium. 100% satisfied with these toys! Ps I also have a hard chewing 12yo aussie that breaks teeth on anything like a bone. He gets thru the rings in minutes with the bouncy ball and nobbly, but takes way longer with the jack shaped one. He also likes to chew the purple ends of the jack, not just the rings. But I don't think they're hard enough to break his teeth. All of my dogs are different style chewers, but there is a good variety of designs so you can find the perfect one for your canine friend!

Dog-approved toy!
This dog toy was initially confusing because the instructions did not say or show where to find the power button and charging port. They were nowhere to be found until I realized I could unscrew the bottom part of the ball from the top (see picture). That revealed the button and port -- problem solved. Then on to the dog test. Our dog was initially confused by and ultimately fascinated with the ball as seen in the video. There are several operating modes depending on how active your dog is/wants to be. The toy seems quite rugged, so immune to rough dogplay, at least from a golden retriever. Our dog considers this a hit!
