My puppy is 12 weeks old and an aggressive chewer. I searched high and low and everyone had lickimats, but no one had the lickimat Keeper. Well, King Duke's to the rescue! The Lickimat Keeper keeps the lickimat from becoming a chew toy. I can safely nest peanut butter in the lickimat and inset it in the Keeper and grab a few minutes of peace to take a shower or fold laundry now without worrying my pup is eating the lickimat along with the peanut butter. I highly recommend this if you have a new puppy or an aggressive chewer! It probably prolongs the life of your lickimat regardless as well.
