Skye's Absolute Favorite Ball! 🐾
Size: 1 Pack, Style: Ball
Hello, I am Skye! I am an Australian Mountain Doodle puppy, and my humans finally found a ball that can keep up with me! The Benebone Natural Rubber Dog Ball is officially my prized possession. Why I give it five paws: The Perfect Chew: It is made of natural rubber, which means it has this amazing, springy texture that feels so good on my teeth. It's super tough, but it still has a satisfying squish when I chomp down on it. Funky Bounces: Because of the rubber and the design, it doesn't just roll in a boring straight line. When it hits the floor, it bounces all over the place in crazy directions, which makes chasing it so exciting. Easy to Carry: The texture makes it really easy for me to grab with my paws and hold onto in my mouth, even when it gets a little slobbery during a long game of fetch.

So far this is the perfect alternative to other wobble toy feeders. Please make a bigger size!
Size: 1 Pack, Style: Pawbler
Why did you pick this product vs others?: I bought the Pawbler because the two most popular wobble treat feeders on the market are plastic, and one of my dogs just absolutely destroys those in no time because he bites them and throws them rather then nudging them and then he has plastic cutting him so I am forced to throw away a costly treat toy/dispenser. I thought maybe a rubber one would work out better. So far my dogs love it, it works well spitting out their kibble, seems to be holding up and is easy to clean and feels like a good weight, not a super flimsy toy. I would love to see it made in a slightly larger size, I think this current size is good for medium dogs. It holds just under a cup of small round kibble but I would like to see one that can hold more and is slightly larger in size. I have 4 german shorthaired pointers, my test subject for this toy is mostly my 70 pounder who bites the toys instead of nudging them and throws them across the room, so it is taking a beating. I think for him a larger size would be helpful in deterring that behavior but I also think this may be too small for larger breeds. Durability: So far this toy looks just like when I bought it. It has no punctures or scratches and unscrews without problem. We have only had it a week or so but we use puzzle/toy feeders to feed our dogs lunch every day so it is pretty easy to tell which toys won't last long. Obviously, I can't speak to long-term durability at the moment, but I can say that most toys similar to this end up already scratched or punctured in a few days, so this is already sturdier when compared to what I have tried before.

Well made and durable, not a toy the pups seek out
Size: 1 Pack, Style: Tug
Well made. Thought our staffies would love since they live tugging with each other. Sadly not something they seek out. We love ALL the benebone chews though!
