SO durable & my Blue Heeler LOVES it!
Color: Purple, Color: Purple
My Blue Heeler tears up almost all of her toys if they’re not rubber. This ball is SO durable and she loves it so much!! We’ve had it for 5 months now. She chews on it every day for long periods of time and it’s showing pretty much no wear and tear. I keep wondering if I’ll ever have to pull out the second one from the box lol. It can be hard to squeak with one hand, but it’s easy enough with 2 hands or if you step on it with your foot. It’s hilarious that every time I squeak it she licks her lips. My girl never actually squeaks it while she’s chewing on it, which is actually a plus cuz it doesn’t get annoying when she’s chewing on it for long periods of time. I also love that the ball helps clean her teeth because of the spikes and the size is larger so it’s easy to take it from her while playing fetch. Overall a fun, durable dog toy!

Totally indestructible!
Color: Purple, Color: Purple
Finally! A toy my aggressive chewer cannot destroy!! Can’t even get the squeaker out! No other toy has ever held up and it’s got some nice bounce to it. Perfect size so it can’t get stuck under the sofa. Furthermore, it aids in cleaning his teeth and he loves them. This is a great money saver too!
Update - 3 months later - still pup’s fav…still whole - still lotsa bounce - still has squeaker intact. As good as new! I’d buy these again but don’t need to 😃!
