I first chanced upon these chews at an event and decided to give it a try. My pup (9yo Maltese) LOVES them. She uses it as a way to let out her energy; so goodbye to nuisance barking! It takes quite some time for her to get through each stick (she gets the small ones) and it does not irritate her skin like other chicken or rawhide chews normally do. The sticks are small enough for her to carry around and hold between her paws for some intense gnawing. These can also be heated in the microwave when she loses interest. Once she gets a whiff of the cheese, she gets right back at it. I highly recommend this, especially if your pup needs to let out her energy. It's a lifesaver! No doubt I will continue buying it so you should, too!
