Takes work and patience!
Success only happened when I covered the exterior with real peanut butter and did as best as I could to squeeze the toothpaste into the center. Even then he licked and licked until the peanut butter was practically gone before he even attempted to bite it. Truthfully, I don't think I want to use this much because it's messy and doesn't clean his teeth as well as I hoped!
