Many types of edible dog chews are available on the market. These chews often do not last long, are unhealthy or are expensive to manufacture.
One type of dog chew on the market is NO HIDEā¢ chicken chews manufactured by Earth Animal. These chews include chicken, chicken gelatin, brown rice flour, organic egss and olive oil. The chicken is rolled out and baked with organic eggs and olive oil.
The prior art chicken chews are expensive to manufacture, due both to the method and the large amount of chicken. The time for dogs to devour the chew can also be short.
The present invention provides a method for manufacturing an edible dog chew comprising the steps of:
The animal hide preferably is rawhide or pork hide.
The length of the chew interior preferably is between 5 and 20 centimeters. and preferably has a diameter of between 1 and 6 centimeters.
Most preferably, the chew interior is made of a single sheet of animal hide having a spiral shaped cross section.
The coating preferably is fresh meat, such as beef, pork, poultry or fish, mixed with glycerin and a starch, such as rice flour to form a syrup. The syrup sticks to the chew interior upon dipping without the need for further ingredients.
The entire pet chew may then be dried in an oven, preferably between 60 to 70 degrees Celcius, until the water percentage is less than 15%, and preferably between 10 and 13%.
The pet chew may then be sterilized in the oven at a temperature of for example between 90 and 100 degrees Celcius and then packed.
The present invention provides a method for manufacturing an edible dog chew comprising the steps of:
The present invention also provides an edible dog chew comprising: an animal-hide material having a cylindrical outer circumference and a lengthwise through opening; and an edible coating coating the outer circumference.
The coating preferably also coats the ends of the edible mixture to close the through openings and enter at least partly into the through openings.
The present invention also provides an edible dog chew comprising: an edible material having a cylindrical outer circumference and a lengthwise through opening; and a coating coating the outer circumference, the coating including fresh meat and glycerin.
The animal-hide materials of the present invention, when used, advantageously can increase durability and chew times. The meat-based coating, when used, advantageously can increase taste of the interior material. The coating with glycerin and/or starch can advantageously allow for good adhesion to the interior and advantageously allow for dipping as a coating method.
One embodiment of a dog chew according to the present invention is described in detail below based on the following drawings in which:
Chew interior 12 is formed by rolling an animal hide sheet, such as rawhide from cattle or porkhide, which is malleable, for example due to soaking in water. The sheet can then be dried to form a chew interior 12.
The chew interior 12 is then coated by dipping the chew interior 12 in an edible mixture 40, so that a coating 14 sticks to the chew interior 12. A portion of the coating 14 may enter into at least one through opening at the ends of the chew interior 12, and help seal any crease or opening at the outer circumference of the chew interior 12. The entire pet chew may then be baked in an oven, and afterwards sterilized in the oven and then packed.
The edible mixture preferably is a syrup made with beef, pork, duck, chicken or fish (85 to 88% by weight of syrup) and glycerin (5 to 7% by weight) and rice flour (5 to 8% by weight).
A detailed example of one embodiment is described below:
Roll animal hide sheet into a circular roll;
Dry in oven and baked at 60 to 70 degrees Celcius until the water percentage is less than 25%
Form a syrup with beef, pork, chicken or fish (85 to 88% by weight of syrup) and glycerin (5 to 7% by weight) and rice flour (5 to 8% by weight)
Dry the whole product in the oven at 60 to 70 degrees Celcius until the water percentage is 10 to 13%
Sterilize the whole product in the oven at 90 to 100 degrees Celcius and pack
The outer coating can be for example 8 to 15 percent of the total weight and the inner chew material 85 to 92% of the total weight of the final product.
