The reasons why dogs love to tear paper:

1. Want to attract the owner’s attention. The dog may be tearing paper because he is too bored, so he uses tearing paper to pass the time. At the same time, he wants to attract the owner's attention by being naughty and make the owner spend more time with him.

2. Retain your nature. It is the nature of dogs to bite. Under normal circumstances, dogs have strong biting ability, which is a need for survival.

3. Lack of trace elements. If dogs lack certain elements in their bodies, they will like to tear paper or even eat paper. This is actually caused by pica.

4. Teeth replacement period. When a dog is in the teething period, the dog's gums will feel itchy and they will want to bite something to relieve the itching of the teeth, so they will bite paper.

5. Feeling hungry. When dogs are hungry for a long time, they will bite paper towels and eat paper to satisfy their hunger.

6. I like the taste of paper. Dogs are very sensitive to smells. When they smell something they like, they will want to keep it for themselves.

7. Unbalanced eating habits. If your dog's usual diet is relatively single and unbalanced, it may cause the dog to eat random things, such as paper, soil, etc. This is actually a symptom of pica in dogs.
