A Sheltie puppy
Many people have dogs for pets. They may get them when they are small puppies and watch them grow. Puppies grow up as small children do, but they do it much quicker. They can be full grown when they are a year old or even six months for some smaller dogs.
A puppy is a juvenile dog. Some puppies can weigh 1–1.5 kg (2.2–3.3 lb), while larger ones can weigh up to 7–11 kg (15–24 lb). All healthy puppies grow quickly after birth...Puppy refers specifically to young dogs, while pup may be used for other animals such as wolves, seals, giraffes, guinea pigs, rats or sharks.

Puppies and dogs come in many varieties just as people do. They have different looks and temperaments. They are social animals who enjoy being around people and other dogs.
The puppies become valuable and much loved members of the family just as babies do. They need to receive love and attention. They should be trained to obey and be good members of the family and society. It takes work and effort to be a good dog owner.
Puppies and dogs should have fresh air and sunshine just as children do. They like to take walks whether it is by their own feet or by being given a ride.
When a dog has its first birthday celebration, it has most likely become full grown. It is no longer a puppy.
It does not take long before a puppy is grown as an adult dog. They will still need love and attention just as they did when they were puppies.
