I really don't know if this is a viable solution - but... I, too, cutoff the chewed up end of the bully stick then put it in the freezer for a while. I keep two of them cycling through thawing and being frozen.

My vet tells me that when they have been chewed on the saliva sets up a perfect medium for bacteria to grow. Guess that is why I started freezing them.
