I bought Gracie a box of Cheweez from Pet Smart. They were recommended by a friend who said that they are vet recommended because they will dissolve in their tummy where as a lot of rawhide type treats will not. If they chew off a chunk and swallow they will just sit in their tummy and can cause major gastric problems. My friends yorkie was in the hospital for 3 days due to this...so she convinced me!! I think there are 4 or 5 in a box.
