Dogs are carnivores. When feeding, animal protein should be prepared in the feed, supplemented by vegetarian ingredients to ensure the normal development and health of dogs. Dogs sometimes eat grass, but they eat very little and occasionally spit it out. Dogs eat grass not to satisfy their hunger, but to clear their stomachs, mainly because of their unique gastrointestinal structure.
The dog's stomach is very big, accounting for about 2/3 of the abdominal cavity, but its intestines are very short, accounting for about13 of the abdominal cavity. Therefore, dogs basically use their stomachs to digest food and absorb nutrients. It is easy to digest meat food, and it is difficult to digest things with "tendons" such as leaves and grass.
Although dogs are carnivores, they can eat vegetables and grains when they are in trouble. Typical wild carnivores' dietary nutrition comes from the stomach contents of herbivores they capture.
In addition, scientists have also found that high-protein foods (eating a lot of meat) can help them prevent muscle tissue damage, such as the dog sled race in Idatarod, Alaska, and other similar situations under extreme pressure. Dogs like to chew bones. This is also the habit of biting prey in the original ecology.
Always give it some bones when feeding. Remember: don't use bird bones, it may puncture the dog's stomach. Dogs generally have the habit of feeding on people and their own feces to varying degrees.
Studies show that dogs acquired this habit through getting along with human beings in the process of tens of thousands of years of domestication, which was one of the important food sources that dogs had to accept in the early period of food shortage in human society.
There are also views that this is a pathological manifestation of dogs in the case of insufficient food, malnutrition, lack of certain trace elements or parasitic diseases. Supplementing trace elements can also reduce this behavior.
