Juvenile pet dog A puppy is a juvenile canine. Some young puppies can weigh 11. 5 kg (1-3 pound), while larger ones can weigh up to 711 kg (15-23 lb). All healthy young puppies grow quickly after birth. A pup's coat color may alter as the pup gets older, as is commonly seen in types such as the Yorkshire Terrier.

Development Born after an average of 63 days of gestation, puppies emerge in an amnion that is bitten off and eaten by the mother pet dog. Young puppies start to nurse practically instantly. If the litter surpasses 6 puppies, especially if several are apparent runts, human intervention in hand-feeding the more powerful young puppies is needed to ensure that the runts get proper nutrition and attention from the mother.

The mom might spit up partly absorbed food for the young puppies or might let them eat a few of her solid food. The mom typically refuses to nurse at this phase, though she may let them occasionally nurse for comfort. Initially, pups invest the big majority of their time sleeping and the rest feeding.

Puppies are born with a totally practical sense of odor. They are not able to open their eyes. Throughout their very first 2 weeks, a pup's senses all establish rapidly. During this stage the nose is the main sense organ used by pups to find their mom's teats, and to find their littermates, if they end up being separated by a short range.

Initially, their retinas are badly developed and their vision is poor. Puppies are unable to see as well as adult pet dogs. In addition, puppies' ears remain sealed up until about thirteen to seventeen days after birth, after which they respond more actively to sounds. In between 2 and four weeks old, pups generally begin to grumble, bite, wag their tails, and bark.

Their coordination and strength enhance, they spar with their littermates, and begin to explore the world outside the nest. They play fumbling, chase, dominance, and tug-of-war video games. Pups are extremely social animals and invest the majority of their waking hours engaging with either their mom or littermates. When puppies are fraternized people, especially in between the ages of eight and twelve weeks, they establish social skills around people.
