Human-height furniture is a fall hazard for a Yorkshire Terrier
A Yorkshire Terrier is injured by furniture she is expected to jump down from, because her fine bones and small joints absorb a landing that would be trivial for a bigger dog. A Yorkie will keep attempting these leaps long after they start to hurt, because reaching her people matters more to her than the landing.
Fit ramps or padded steps at the Yorkshire Terrier's sofa and bed, with a grippy surface she can manage slowly, and place them where she actually climbs rather than where they look tidy. Lift her down yourself when she is excited, since excitement is when careful descents are forgotten.
Drafts, cold floors, and a bed in the wrong place
A Yorkshire Terrier is chilled by a sleeping spot that suits a larger dog, because her tiny body and fine, silky coat lose heat quickly on cold tile or in a draft from an outside door. A bed on a kitchen floor near the back door, a crate in an unheated hallway, or a house kept cool overnight can leave a Yorkie shivering, restless, and reluctant to settle. Young and elderly Yorkshire Terriers feel this fastest, and shivering through the night is poor rest by any measure.
Move the Yorkshire Terrier's bed to a warm inside wall, raised off cold floors on a padded base, with a blanket she can burrow into rather than only lie on top of. Keep her daytime pen in the room the family actually heats and uses, so she is warm and included at once. If shivering continues in a warm room, or comes with weakness or loss of appetite, contact your veterinarian the same day rather than adding another blanket and waiting.
Underfoot, unsupervised, and overwhelmed
A Yorkshire Terrier is at risk in a busy home layout with no protected zone, because she is small enough to be stepped on in a doorway, knocked by a swinging door, or grabbed suddenly by a well-meaning child.
Give the Yorkshire Terrier a pen or gated corner in the family room with her bed, water, and a chew inside, where she can be part of the household without being in its traffic. Set the rule that she is stroked where she rests and never lifted by children, and that a sleeping Yorkie is left entirely alone. Teach everyone to shuffle-check before stepping back in the kitchen, and to open doors slowly at her height, because her favorite waiting spot may be directly behind one.
Tiny hazards left at Yorkie height
A Yorkshire Terrier is poisoned and injured by small hazards bigger dogs never reach or never bother with, because everything on a low shelf, in an open handbag, or dropped on the floor is at her nose level. Loose tablets, hair ties, small toy parts, and trailing charging cables are all within easy reach of a curious Yorkie, and her size means a small swallowed object is a proportionally bigger emergency. A home safety sweep done at knee height misses almost all of what she can access.
Do a Yorkshire Terrier safety pass on your knees, room by room, moving medicines, small objects, and cables into closed drawers and latched cupboards. Keep handbags zipped and off the floor, and check under sofas for dropped items before she goes exploring there. KinsLe Family Sharing lets a Yorkie's household keep that low-level hazard list and her ramp and pen rules in shared notes, so a tidy-up by one person does not quietly undo another person's safety pass.
