A puppy is a juvenile dog. Some puppies can weigh 0.45-1.36 kg, while lager ones weigh up to 6.8-10.4 kg. All healthy puppies grow fast after birth. A puppy coat may change color as they get older, as it is commonly seen in breeds such as the Yorkshire terrier.
Puppies are really playful especially with their mothers, they also play with their kinds.
