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 he’s either much smarter than every other dog or the treats fall out too easy..I believe it’s the ladder.

Great for enrichment treats for dogs

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. It’s super easy to use and strong against dogs bites and chewing

Keeps My Dog Busy and Happy!
Size: Large
I bought this 2-pack of treat-dispensing toys for my large dog, and they’ve been a total win. The rubber is strong enough to hold up against heavy chewing, but soft enough that it doesn’t hurt his teeth. I like that it’s large, so I can fill it with kibble or small training treats, and it keeps him entertained for a long time.
The best part is how much mental stimulation it gives—he really has to work to get the treats out, which helps with his energy and boredom. I also noticed it slows down his eating when I use it for kibble, which is a huge bonus since he usually gulps food too quickly.
Getting two in a pack is great value. I keep one stuffed in the freezer with peanut butter for a cool snack on hot days and use the other for everyday play. Both clean easily with warm water and soap.
✅ Durable and safe rubber
✅ Keeps dogs busy and mentally stimulated
✅ Doubles as a slow feeder
✅ Great value for a 2-pack
Highly recommend if you want something affordable, durable, and actually fun for your dog!

Chef’s Kiss! Quality Product at an Amazing Price!
Size: Large
The large is a perfect size for my 66# and 110#. If you have a smaller dog, consider a medium. Fill them with peanut butter, 1/2 banana each, wet kibble (paste) or pumpkin puree, and put into the freezer. Not as stiff as their Kongs. Both dogs are strong chewers and these have held up. Clean the inside with a baby bottle brush.
