Twistix is a Wheat Free Dog Treat for Good Oral Hygiene:  I rescue dogs, and you would think they would like any kind of treat or chew.  NOT!  But Twistix has proven to be an all-time favorite with my fosters as well as my own dogs.  It is wheat free and must taste good because they "dance" when they hear me get the bag out of the cabinet.  The twisted design helps to remove plaque and tartar.   Twistix comes in two sizes so small and medium dogs can enjoy a size that fits their mouths.  I especially like the product because it keeps the dogs chewing for quite some time!
