Good quality
Color: Croissant
The quality is good, the material is very hard and heavier than I expected. My dog is too smart for this. After the first time she figured out to just let it sit and melt then drink it up in 10 seconds.

The Best!
Color: Croissant
Out of all the stuffable, freezable dog treat toys I’ve tried over many years with several dogs, this one is #1! So easy to clean and freezing the little goodie cup that you insert in to the toy is so much easier than trying to stuff a small hole! The extra little grooves on the outside I fill with no sugar no salt peanut butter and my pup loves it! This is a heavier toy, so not sure how a small dog would do picking it up or carrying it around, but our 45 lb guy has no problem! Seems like it is very durable and just might last forever!
