An Ice Cream Cone for Dogs Who Have Never Paid Taxes
Style: Frosty Cone, Size: Small (Pack of 1)
Bought this for my dog thinking it would provide “a few minutes of enrichment.” It became an event.
The second I pulled this thing out of the freezer, my dog reacted like I had personally returned from a heroic quest carrying the sacred treasure of his ancestors. Absolute full-body joy. Olympic-level tail wagging.
The rubber feels sturdy, the opening is easy to fill, and freezing treats inside keeps him occupied long enough for me to answer emails, drink coffee, and briefly remember who I was before becoming a full-time employee of a small furry creature.
I’ve filled it with peanut butter, yogurt, treats, and one regrettable attempt involving pumpkin puree that turned my kitchen into a seasonal crime scene.
Best part: it’s durable enough to survive enthusiastic chewing without immediately looking like it lost a fight with a lawn mower.
Five stars. My dog now stares at the freezer with religious devotion.

Great treat toy especially for frozen treats
Style: Chilly Penguin, Size: Medium/Large (Pack of 1)
This is cute! Very solid and chewable. To ensure a longer play time it does great for popping in the freezer after filling with peanut butter, yogurt, pumpkin, applesauce, broth, dog ice cream etc ...
It's been so much cleaner and easier than putting it in a dish; the treat lasts longer and the dog is entertained longer.
Whether frozen or not, this toy is very easy for my dog to get everything / lick clean. It's very easy to clean either putting in the top shelf of dishwasher or hand washing with a bottle brush.
Treat of no treat, this is entertaining for my dog. He likes to simply run around with it in his mouth or randomly chew on it. This is different from his balls or bones because it's kind of flat and thin.
Good buy and great to help cool him off from the warm weather.
