I love the size of these and the sturdiness. I freeze bone broth and put it in the crate or give it to dogs when it gets warm out. To help them cool or help them with teething. They have decimated other holders of frozen liquid, but these have lasted well. They also do not get sharp edges when chewed on by English bulldogs.

Its a hit for my 9lb chewer!

Style: Chilly Penguin, Size: Small (Pack of 1)

So far so good! My Pup is a chewer and destroys most of his toys. This has been great to keep him happy and occupied for about an hour. I work from home, so when I know I need to keep him busy this is perfect. Ill keep an eye on it to make sure he doesn't break it, but it is pretty solid and thick. He can get through a puzzle in seconds, so this has been so good for him. Ive done mostly broth and veggies, some kibble. Even yogurt and peanut butter. Right now he gets it twice a day. He spends about an hour with it and then hes so tired hes ready for a nap. Once around mid day and another late evening before bed. Im ordering another to keep for when I have to leave him home alone. He cleans it pretty well, but Ive found soaking in hot water also loosens any bits left behind. Because its small, I'm not worried about extra calories.
