Pawbler FAIL: First time our dog bit the ball, it popped open and dumped all the kibble.
Size: 1 Pack, Style: Pawbler
I would not recommend! We have a 48# dog and within minutes of giving it to him, the Pawbler was open and all of the kibble was in a pile on the ground. I had washed and dried the Pawbler, added kibble, and tightened the lid as tight as possible. Imagine my surprise when, within minutes of giving it to him, the lid was off and all the kibble was on the ground. I thought it was a fluke so then I made an extra effort to make sure the lid was super tight...and the same thing happened. This time there was no food inside so he started chewing on the two parts. Within minutes of that, he'd chewed/damaged the rubber on both the body and the lid. I took it away as I didn't want him to destroy/eat any of the rubber bits. I was surprised he could even get the Pawbler in his mouth. It's heavy and he is a medium sized dog. He has the Benebone Bone, the WestPaw bone, the WestPaw ring that he chews on all of the time and none of those are showing any type of wear so to see this opened/chewed within 15 minutes makes me think this was defective. I am returning and hoping for a refund. DO NOT BUY! Poor value for the money. Not durable. Not chew resistant.

Just what I was looking for to slow my large dog while eating
Size: 1 Pack, Style: Pawbler, Size: 1 Pack, Style: Pawbler
I needed something for my 50-pound dog to slow down her eating. The usual slow-feeder bowls and mats weren't really slowing her down much and I wanted her to have to think a little bit. She's not smart enough for puzzles though. So I got this kibble dispensing toy. My dog is not a chewer so I don't have to worry about her destroying it.
LOVE: holds a little more than a cup of kibble, dispenses different sized kibbles, heavy weight so it wobbled around a lot without going too far away, QUIET- I couldn't bear the noise of hard plastic dispensers clacking around and this one is very quiet on our hardwood floors, kept the dog busy for at least 20 minutes. It's really all I was hoping it would be. And, well, as you can see in the video, the cat is happy about it too...
As with all of these dispensers, there will be a couple of kibbles left inside that are hard to get out. But that gave my dog something to do overnight. She spent a long time getting that last kibble out. The slight scent they add to the natural rubber is not a problem at all. This dispenser is absolutely worth the money, it's going to last us a very, very long time.

People are doin it wrong
Size: 1 Pack, Style: Cone
Cheap and durable and huge. The bad reviews are from people who aren’t using it right. Step 1) plug hole with a smear of peanut butter. 2) put a low calorie but appetizing mix of whatever you want: yogurt, pate, pumpkin puree, blended with frozen veggies on the walls 3) freeze cone for 30 mins. Hole will be sufficiently plugged to add liquid. 4) fill the rest with water or bone broth and freeze overnight to make it a changing ice block.

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.
