The reasons why Labrador eats grass:

1. When the dog is hungry and cannot find food, it will eat grass. Feed your dog on time.
2. When a dog lacks trace elements, it will lead to pica and eating indiscriminately. The dog can be fed trace element tablets.
3. When dogs feel bored, they will also eat grass. Owners can play with their dogs more often.
4. When a dog's stomach is uncomfortable, he will eat grass to induce vomiting. You can feed the dog some probiotics to regulate his stomach.
5. Dogs are curious about grass and may want to take a few bites to taste it. The owner should stop it in time to avoid pesticide residues on the grass, which may cause poisoning of the dog.
