Great toys. Bouncy, chewable long term.
Size: Medium, Size: Medium
We got these for our puppy and to see how they would compare to kongs.
Our dogs love these more than the kongs and so far, with two chewy dogs, they have not destroyed these yet.
They are very bouncy and provide a lot of chasing fun.
We will be buying more and we recommend these.

Durable
Size: Large
Excellent material. I wish the hole was a little smaller to keep the treats in better. Also wish they were a little larger and/or oddly shaped so as not to fit under the sofa. Still totally worth it.

Subtle, great dog toy design!
Size: Large
These things are amazing. Stuff them with peanut butter and treats and freeze them of course, but football spike them across the yard to drive your overly hyped dog nuts! And the hole allows you to safely pry it out of a tug battle , just a great design! And it can bobble across a small living space without getting lost like a ball would. Love it!

Treats fall out way to easy
Size: Large
Kinda sorta awful at holding treats in it, they just fall out without my dog even having to touch it really. I spread peanut butter on the inside of the toy and freeze it..works much better that way, nay, works amazing that way. I got this toy to stimulate his brain, so heβs either much smarter than every other dog or the treats fall out too easy..I believe itβs the ladder.

Great for enrichment treats for dogs
Size: Large, Size: Large
Great product and durable. We fill them with wet dog food and freeze it then give it to our dogs as enrichment treats. They love it. Itβs super easy to use and strong against dogs bites and chewing
