The reasons why dogs like to eat paper:

1. It may be mistaken for food, which also means that the dog may be hungry.

2. It may be that the dog is in the teething stage and eats paper to grind its teeth.

3. The dog may be at home alone, has a lively personality, deliberately makes trouble, and eats paper out of boredom.

4. It is also possible that the dog is in a bad mood or emotionally unstable, causing the dog to eat paper to vent its emotions.

5. It may be due to the lack of trace elements in the dog’s body, which causes the dog to eat paper and other random things.
