Dogs eating grass may lack trace elements and develop pica. If the dog eats grass frequently, the owner should adjust their eating habits in time and change the dog food if necessary. Special attention should be paid to the fact that the grass that dogs eat must not be treated with pesticides, otherwise the dog will be poisoned if it eats it.

Under normal circumstances, dogs will also eat a small amount of grass, so pet owners do not need to worry too much. Dogs have the habit of licking their fur, and the licked dog hair often accumulates in the intestines and stomach, forming hair balls, causing discomfort to the dog. At this time, the dog will take the initiative to eat some fresh, green and tender grass to help the dog hair in the body to vomit smoothly.
