Why do dogs eat grass?

First, the main reason why dogs eat grass: In order to cure diseases, because the dog's constitution itself has the function of forming vitamin C, dogs do not need to supplement vitamin C, but sometimes this function of dogs will fail. Because of the loss of this function, they can't make vitamin C by themselves, which will reduce their resistance to viruses, so they will eat grass to supplement vitamin C. In addition, when dogs are unwell, they will also look for the roots of plants containing salicylic acid to eat (salicylic acid is also the raw material for making aspirin).

Secondly, in fact, we can observe carefully that when a dog swallows grass, if it is kept indoors in a place where there is no grass, the dog will swallow other objects, such as rags, plastic bags, paper towels and even small rubber toys. If it is found that dogs often eat grass, the owner should be vigilant. It must be that the dog is seriously deficient in vitamins, eats indiscriminately and has pica. At this time, it is necessary to supplement the dog with multivitamins.

Some parents give their dogs vegetables, but they often find that they have not improved after eating them for a long time. That's because there are only a few vitamins in vegetables, which are not enough to supplement the vitamins that dogs lack.
