A "pup" is a young dog, typically less than a year old. Puppies are known for their playful behavior, curiosity, and rapid growth. They are often social animals, enjoying interaction with humans and other dogs. Pups require special care, including proper nutrition, training, and socialization. They go through various developmental stages, including teething and learning basic commands. Responsible pet ownership involves providing a safe environment and regular veterinary check-ups to ensure their health and well-being.
