I put Zena's bully sticks in her Kong when they get down to about two inches. The Kong holds it firmly enough for her to chew it down to almost nothing. I get my moneys worth and she has a blast down to the very end. Try it for yourselves! Oh, I had to open up the hole in the Kong a bit to fit the stick in. Very easy to do with a sharp knife. Be careful and don't cut your hand! |
