Why is my 7-week-old chihuahua puppy biting and destroying things?

Updated on September 23rd, 2025

Pet's info: Dog | Chihuahua (Smooth Coat) | Male | unneutered | 1 year and 1 month old | 3 lbs

Ok so I recently got a chihuahua he is 7 weeks old he was born November 22 He recently started biting us really hard. He doesn’t let go. He starts acting weird like destroying is bed and stuff. But after some minutes hes calm. He also eats a lot I think he’s obese. He exercises a lot too.

This is a common problem in puppies and young dogs, as they sometimes need help figuring out how to appropriately play with humans, and what objects/toys are okay to chew on. Visit the following link for more information on how to work with Osito at home to reduce play biting https://www.aspca.org/pet-care/dog-care/common-dog-behavior-issues/mouthing-nipping-and-biting-puppies. I also strongly recommend working with a reputable dog trainer in your area who uses positive reinforcement techniques to make sure Osito is not accidentally getting mixed signals that are making him think that biting is ok. Taking Osito to a puppy class to help his burn off some excess energy and learn how to play appropriately is also very important, as is regular exercise that can provide an outlet for his energy.
