My 11 lb chihuahua mix only likes the yak chews when they are microwaved. When they get crunchy, she loves them - but they make a huge mess when she eats them. Crumbs get everywhere! I bought them so she would have something to chew on for awhile because she is hyperactive and very mouthy. She can eat the crunchy ones in 5 minutes so I canβt use them as hoped.
