How Do You Describe Papillons, Please Read Description?

people describe papillons as sweet, and lovable, they say they arn’t yappy, and love to be around people, but my cousins have a papillon who is terrible(most of the time) she’s yappy, she pees on beds (even though shes potty trained) she hates when people pet her, and once she was on my bed and i was laying down and i set a pillow near her and she started growling at me and barking so when i took the pillow away she tried to bite me, does anyone else think papillons arn’t as sweet as they should be?
