It is normal for dogs to eat grass by themselves. This is to help their own gastrointestinal digestion. Animals in nature have this habit. Some animals will eat stones and other things to help themselves digest. This is normal behavior. Parents don't need to worry. We only need to pay attention to whether the dog’s feces is normal.

Tip:

In addition to eating grass, dogs also retain a series of instinctive behaviors such as howling like wolves and burying things in their nests. Parents do not need to pay too much attention to these behaviors.
