Why do puppies like to tear paper?

Puppies liking to tear paper may be due to several reasons:

Teething period: Puppies usually start teething between 3-7 months of age. During this process, their gums itch, which prompts them to bite and tear things to alleviate the discomfort. If this is the case, owners can purchase a chew toy or a teething bone to help their puppies cope with the teething process. Additionally, owners should also pay attention to supplementing calcium, as a lack of calcium can lead to delayed falling out of old teeth, resulting in an unpleasant smell.
Deficiency of trace elements: If the puppy tears paper and eats it along with other non-edible items like walls, nails, soil, or feces, it may be due to a deficiency of trace elements, which can cause pica. In this case, owners should promptly stop their puppies from doing so, and supplement trace elements and other nutrients to avoid gastrointestinal discomfort. It's also essential to provide a balanced diet for the puppy, with dog food as the main staple.
Boredom: Puppies are full of energy, and when they are left alone at home for extended periods without anyone to play with, they may become bored and tear tissues into pieces everywhere. In this scenario, owners must stop their puppies immediately and guide them to develop good habits by keeping tissues out of reach. Providing more toys for the puppy to play with can also help distract them from tearing paper.
