The common ancestral origin of any of a number of small canine (dog) breeds and mixed breeds that have the

shared trait of repeated or staccatic barking at just about anything or anyone at anytime.”Yappanese” is a variant of this term that may be sometimes used with the same meaning.

Every time the door bell rang the little dogs exhibited their Yappinese ancestry.

That little dog must be at least part Yappinese the way it won’t stop barking at everything.
