Training a puppy requires significant patience and consistency to ensure the animal develops into a well-behaved adult dog capable of following complex commands.
From earlier puppie (“a woman's pet dog”), of uncertain origin, but probably from Middle English puppee, poupee, from Old French poupée, popée (“a doll; puppet”). More at puppet. Mostly displaced native Middle English whelp (“puppy”), from Old English hwelp, whence Modern English whelp and whelpie.
The plural form is 'puppies'.
