As far as housebreaking My Seymour will jump up on the bed and wake me up by putting his paw on my face and staring down at me ( He is such a cutie ) Or he will go scratch on the door Wherever you heard that from they must have been too lazy to take the time and be consistent ! I crate trained Seymour My moms yorkie Abby stands by the door She was trained with other yorkies they actually trained her They are a very smart breed So smart actually they get you wrapped around their paw right away ! Also being a groomer there are alot of pets that have accidents and that is expected most yorkies ive seen will let it be known when they need to go ! The older they get of course they have a hard time my moms yorkie Arletta RIP was 17 when she passed and we would leave potty pads down for her . She was so sweet !!!Yorkies are genious !
