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!

Bump on tongue
Color: Croissant, Color: Croissant
It’s a good idea but should be made with hard rubber and the back should not be able to come off. It gives off shards of plastic and gave my dog bumps on his tongue. I do love the idea and it keep my dog busy in the morning while I had my first cup of coffee and before everyone woke up.
