Abstract: A pet chew has an elongated tube having a wall extending between two ends. The tube has a length between the ends. The wall forms an interior cavity that extends along the length of the tube. The wall is made of extruded material of animal meat, animal skin and plant material such as starch and grain. The interior cavity is hollow. In one embodiment, each end of the tube is tied into a knot, with the tube forming a central shank extending between the knots. In another embodiment, a wrap is located around the exterior of the tube. The wrap has a different appearance than the tube. In still another embodiment, plural tubes are provided, which tubes are braided about each other.

Abstract: Pigskin is processed to provide a bleached, expanded skin used in dog treat or chew products. The raw pigskin is dehaired and then daubed with an alkali mixture of an alkali liquid, alkali enzymes and lime, the mixture having a pH of greater than or equal to 12. The alkali mixture dissolves the colloidal protein. The alkali is removed by alternately rinsing the skin in water and agitating the skin with first ammonium chloride or ammonium sulfate, and then second with ammonium chloride or ammonium sulfate, and pancreatic enzymes. The skin is agitated with sodium carbonate and a degreaser to remove the fat. The skin is then washed with hydrogen peroxide, which bleaches and expands the skin. The skin is then formed into a dog product and dried.

Abstract: A chew product for use by animals is made of skin such as rawhide or pigskin. The skin is infused with chlorophyll or mint or both to freshen a dog's breath and also with sugar to increase palatability. The interior portion of the skin can be perforated, such as by cutting, before the skin is formed into a product. The perforations allow a dog's teeth to penetrate into the product and be scraped clean by the edges of the perforations. The skin is dyed green from the chlorophyll. The dyed skin can be used either alone or in conjunction with another color skin to make a product. The dyed skin and a bleached white skin combine to make an attractive product.

Abstract: A treat for a dog made from pig skin taken from the body of the pig. The skin is cut to a desired shape, folded or rolled and pressed between two dies to form a shaped member which may be a replica or representation of a pig's ear, rib, or a pork chop. The pressed member is heated, smoked, and sterilized.
