WEST PAW Funnl Large 4.25" Tropic Red

Q: Hi, Does anyone know if a yak cheese dog chew would fit in this?

It's made to fit the Earth Animal Chews (not stix). So if you have a yak chew that is similar in thickness, it might work. My experience with yak chews is that they vary in size depending on the brand.

Q: Will this work with a bully stick?

No, it is made to work with the Earth Animal Chews (not their stix). A bully stick is too skinny

Q: Do these come in a different size? Specifically Shorter? For use with a small dog wasting over 4 inches of bone is a way too much

I use this with a 4" bone with my dog, and leave one end sticking out. Eventually, he figures out how to pull the whole thing out of the Funnl, but having the Funnl there increases the difficulty of chewing the bone and doubles the amount of time for him to go through a No Hide bone.
