Query: Great with peanut butter

Great toy, I put peanut butter on the inside and let my dog lick out the peanutbutter. It keeps her busy for at least 30 minutes and she loves it. If you put peanut butter inside of it and then freeze it it seems to take her longer to get the peanut butter out. This is certainly her favorite treat.
