noun
puppy
PUP-ee/ˈpʌpi/
A dog that has not yet reached adulthood.
The fluffy puppy sits beside an adult dog's much larger paw.

Etymology
The likely connection is with a doll: a small pet dog may have been called this because it was petted like a doll. The meaning shifted from a small pet or toy dog to a young dog.
In context
