The floor decides whether she can rise
Stiff joints turn rising into the hardest work of a senior pig's day. Concrete that is wet, polished or icy defeats her before she starts, so give her grip: a roughened or rubber-matted base under the bed, kept dry, with deep straw she can push against rather than slide on. Watch her rise in the morning — repeated attempts, splayed front legs or giving up and lying back down mean the surface or the bedding depth needs changing before she injures herself trying.
Room to turn without twisting
Pigs turn by walking a small circle, and an arthritic pig needs that circle bigger. Widen the pen so she can swing her whole body in one easy arc to reach bed, feed and water, instead of performing tight pivots on sore hocks. Keep fixtures out of the turning space: a trough jutting into her circle or a feeder she must back away from will eventually trap or topple her. If she shares with younger pigs, give her a sectioned resting area they cannot barge her out of or force her up from.
A wall to lean on, a bed worth lying in
Senior pigs use walls. A solid wall or strong rail at the side where she rises and lies gives her something to brace against, and many old pigs deliberately sleep against it. Make her bed deep enough to cushion bony hips, elbows and knees — an old pig carries less fat over those points than she once did — and keep it dry right through, because damp bedding leaves stiff joints colder and tempts her to lie in the dirty corner instead. Position the bed away from the dunging area so she is not choosing between comfort and cleanliness.
Audit the pen again when the season turns
A pen that suits a senior pig in summer can fail her in winter. Heat is her summer enemy — she cannot sweat — so the pen needs shade over part of the floor, cool lying ground or a damp patch she can press against, and water she can reach without effort in the hottest hours. Winter reverses the problem: draughts at floor level and damp bedding stiffen her joints and steal her rest. Walk the pen at pig height twice a year with the season in mind, and adjust bedding depth, bedding place and wind protection before she pays for the change.
Food, water and warmth within easy reach
Feed on the floor or in a low, wide trough she cannot tip and does not have to step into, placed where she reaches it without crossing the slippery dunging patch. Water must be drinkable without rearing up at a high nipple or dipping into a deep bucket that presses her neck — a low, heavy bowl or a drinker reset to her comfortable height. Warmth counts too, because a senior's problem is more often cold stiffness: draught-proof her sleeping corner while keeping ventilation above her back. Note how she moves, eats and rises each day, and put those observations on a rota — KinsLe Care Teams lets you assign bedding, feeding and mobility checks to whoever is on duty and mark each one done.
