Technical Field
The invention relates to the technical field of dog chews, in particular to a harmless and environment-friendly dog chew and a manufacturing method thereof.
Background
In recent years, more and more Chinese families have started to raise pets at home, with dogs being one of the most common pets. However, many breeders still maintain the old dog-feeding concept for pet dogs, for example, the conventional human food feeding pet dogs have different nutritional requirements due to the difference of physiological structures and metabolism between dogs and humans. The ancient breeding mode has a plurality of problems, such as the common bad smell of the pet, which not only affects the health of the pet, but also affects the relationship between people and the pet.
The dog chews are snack products for cleaning oral cavity and tartar of pets, which are generally formed by extrusion molding or compression molding, the tartar can be removed by the friction force between the product and teeth during the feeding process of the pets, and meanwhile, some effective components can refresh breath, so the dog chews can be used as food for cleaning oral cavity and tartar of the pets.
