disclosed herein are edible animal toys having a hollow interior and at least one opening to the hollow interior . the opening is configured to allow treats and edible objects to be placed into the hollow interior . an animal , such as a household pet , for example a cat or a dog , can methodically remove the edible objects from the hollow interior . animal toys having a hollow interior with an opening are known in the art . for example , u . s . pat . nos . 7 , 389 , 748 , 7 , 591 , 234 , and d624 , 711 , all of which are incorporated by reference herein in their entirety , including the drawings , disclose animal toys where an edible treat or food item can be placed inside of the toy , to be removed by the animal . the challenge of removing the edible object from the toy provides long periods of amusement for the animal and prevents rapid boredom and disinterest . the animal toys disclosed herein are different from those described in the aforementioned u . s . patents . the body of the presently described toys is made of edible materials , whereas the aforementioned u . s . patents describe a toy whose body is made up of inedible polymeric materials , such as plastic or rubber . having an edible body provides further advantages to the toy . for example : animals are attracted to the smell of the edible toy and prefer the edible toy to the inedible one . consequently , the edible toy makes it possible for an otherwise uninterested animal to get the benefits of the mental stimulation and exercise that the inedible toy provides to the interested animal . similarly , an animal that normally does not play with rubber / plastic / inedible treat toys is attracted to and plays with the edible treat toy . senior dogs who have lost the interest and enthusiasm for inedible treat toys are newly motivated to play with an edible treat toy . dogs with health issues , such as loss of sight or hearing , have an easier time playing with the toy since they can more easily target it using their sense of smell . certain inedible toys break down into pieces over a period of time . this creates certain negative effects , such as dispersed debris or intestinal blockage when the animal ingests the piece . the edible toys are designed to be safely broken down and eaten by the animal . some animals have allergies to plastic or rubber . these animals can get the benefit of the mental stimulation that the toy offers by using the edible toy . the edible toys do not require any cleaning or maintenance since they are always in the process of being broken done by the dog as it &# 39 ; s playing with the toy . the edible toys can be formulated to meet specific dietary needs . as discussed herein , the edible toys of the present invention are configured to contain edible treats . unlike with plastic , rubber or plush toys , when the treats are emptied the edible toy is still engaging and desirable to play with for the dog . it is an ongoing motivator even when the treats are gone . the edible toys engage a dog &# 39 ; s hunting instincts and prey drive from the outset . it is not necessary to train the dog on how to use it unlike with plastic / rubber / plush treat toys that require initial training . in some embodiments , the body of the edible toys disclosed herein is made up of baked materials . in other embodiments , the body of the edible toys disclosed herein is obtained through an injection molding process . in these embodiments , an edible dough is used instead of the traditional rubber or plastic in the injection molding process . in either case , the dough is cured , either by heating or by any other curing process . in some embodiments , the cooling of the dough after baking or injection molding is curing . once the dough is cured it hardens . the hardening can be either due to the “ cooking ” or the drying of the dough . the cured dough , in certain embodiments , is hard so that it provides a challenge to the animal that prefers chewing hard objects such as bones or pieces of wood . however , the cured dough exudes an aroma and provides a taste that is attractive to the animal and maintains its interest in the toy . baked animal toys , and edible animal toys obtained through injection molding process are known in the art and any number of them can be used with the present toys . yet , in some embodiments , the edible toys can be formulated to meet specific dietary needs . the dough for the body of the toy can be shaped in any shape prior to curing . after the toy is cured , the toy will retain that shape . for example , the toy can be made in the shape of a bone , a cylinder , a sphere , or other shapes that are both aesthetically pleasing and are interesting to animals . in some embodiments , the toy is molded and cured in separate pieces , for example two separate halves or three or four or more separate parts . by this method , the hollow interior and the at least one opening can be created by forming depressions in the dough . after the separate parts are molded and cured , they can be put together and sealed with edible glue or similar materials . in some embodiments , the separate parts are cured partway , i . e ., to the point where the part will retain its shape , and then the various pieces are put together to form the toy and sealed with more of the same dough . the complete toy is then cured further to obtain the desired firmness . thus , in these embodiments , the “ glue ” is more of the same dough and the toy will present a seamless exterior . in some embodiments , the edible food or treat is placed inside the depressions before the separate parts of the edible toy are joined before curing . in these embodiments , the treat cures or bakes along with the toy . in some of these embodiments , the toy provides a greater challenge for the animal to extract the treat because the treat can be larger than the opening . in certain of these embodiments , the treat is also baked goods , but is softer than the body of the toy . in some embodiments , the treat completely fills the hollow interior . in these embodiments , the toy is analogous to a cream - filled cannoli , having a softer interior treat enclosed within a harder edible body . in other embodiments , the treat is in several smaller pieces that can move or rattle around inside of the toy , analogous to a chocolate egg having smaller pieces of candy enclosed within it . in some embodiments , the various parts are made up of different types of dough . these toys provide a more colorful exterior , which is pleasing to the animal owner , while at the same time provide a variety of tastes for the animal that prevents boredom and maintains the animal &# 39 ; s interest in the toy . the hardness of the cured material can be varied depending on the targeted animal . primarily , the toy must be hard enough to provide a chewing or gnawing challenge to the animal . at the same time , the toy must not be so hard that it does not flake off to provide tasteful enjoyment . larger animals having stronger teeth and jaw muscles will require toys that are harder than smaller animals . it is well - known in the art to make cured animal treats of varying hardness . in some embodiments , the opening is large enough to allow the animal owner to insert treats into the toy , but not too large so that the treat would immediately be released from the toy . in some embodiments , the opening has flaps that are made up of softer edible material . the flaps bend inward and allow the treat to enter the hollow body of the edible toy but provide a temporary barrier for the treat &# 39 ; s exit . in some embodiments , the dough comprises one or more of the following ingredients : one or more types of starch , one or more types of oil , one or more types of protein , one or more types of fruit , one or more types of vegetable , one or more types of flavoring , one or more types of supplements , one or more types of stabilizers or preservatives or other miscellaneous ingredients . in some embodiments , the starch is selected from the group consisting of rice , wheat , potato , corn , brown rice flour , white rice flour , rice powder , barley , oats , sweet rice flour , tapioca starch , oat fiber , and potato starch . in some embodiments , the oil is selected from the group consisting of flaxseed , chia seed , fish oil , sesame oil , hemp seeds , and mixed tocopherols . in some embodiments , the protein is selected from the group consisting of chicken meal , chicken , beef , fish , pork , turkey , meat , liver , corn gluten , gluten , soy , soy protein concentrate , peanuts , and peanut meal . in some embodiments , the fruits and vegetables are selected from the group consisting of pumpkin , sweet potatoes , alfalfa , cranberries , parsley , dehydrated carrots , blueberry , pomegranate , apple , assorted vegetables , tomato , and peas . in some embodiments , the flavoring is selected from the group consisting of garlic , brewers yeast , peppermint oil , mint , garlic powder , hickory , mesquite , fennel seed powder , parsley oil , green tea extract , vanilla , natural chicken flavor , rosemary , ginger , anise , carob , dill , cinnamon , pumpkin flavor , and peppermint . in some embodiments , the binder is selected from the group consisting of glycerin , gelatin , lecithin , carageenan gum , water , cellulose powder , dionized water , vegetable gum , and pectin . in some embodiments , the supplement is selected from the group consisting of calcium carbonate , cholecalciferol , taurine , fructooligosaccharides ( fos ), bacillus coagulants , l - carnitine , glucosamine hydrochloride , chondroitin sulfate , capsaicin , dl - alpha tocopheryl acetate , and l - ascrobyl - 2polyphosphate . in some embodiments , the miscellaneous ingredient or stabilizer or preservative is selected from the group consisting of colorings , tricalcium phosphate , citric acid , sodium hexametaphosphate , sodium diacetate , sodium tripolyphosphate , and titanium dioxide . in one embodiment , the edible toy , as disclosed herein , comprises the following ingredients : rice flour , vegetable glycerin , gelatin , water , cellulose powder , calcium carbonate , sweet potatoes , lecithin , carrageenan gum , natural pumpkin flavor , garlic , brewers yeast , and peppermint oil . those of skill in the art recognize what ingredients to choose for a particular line of edible toys . for example , a high protein edible toy is prepared to meet the needs of a particular dog that may be on a high protein diet . similarly , a toy is prepared with no protein at all but with starch and various flavorings for a dog who may be on a low protein diet . various vitamins and supplements are introduced into the toys to fit the needs of various dog populations . as noted above , the edible toys disclosed herein are baked or prepared by injection molding . in some embodiments , the ingredients are selected for the particular line of toy ( e . g ., a high protein , a low protein , or a high vegetable line of toys ). the ingredients are mixed and kneaded into a dough . in some embodiments the kneading is performed manually whereas in other embodiments the kneading is performed by a motorized mixer . the dough is shaped into the desired shape and the shaped dough is placed in an oven for baking . in the embodiments where the edible toy is prepared by the injection molding process , the ingredients are selected , as discussed above , and blended , mixed , or extruded to form homogenous pellets . using methods known in the art , the pellets are then processed into a molded article utilizing injection molding , compression molding , transfer molding , pressure forming , or other similar molding methods . the molded article is then removed from the molding machine and cooled .
