Abstract

An edible pet chew has a member of meat based material chewy sheet. The “meat based material” chewy sheet imitates the durability and strength property of known rawhide sheet and simultaneously has inherent attraction to dogs with meat in its formula. A first aspect of present invention is that, the edible pet chew has a SINGLE chewy sheet of meat based material. A second aspect of present invention is that, the edible pet chew has a meat based material chewy sheet member and additionally an edible material member being wrapped therein. A third aspect of present invention is that, the edible pet chew has an edible material member and additionally a meat based material chewy sheet member being wrapped therein. A forth aspect of present invention provides a method for making the edible pet chew with the essential member of meat based material chewy sheet.
