Start at Netherland Dwarf Height
A Netherland Dwarf is one of the smallest rabbit breeds, compact and quick, with a head that can test openings larger rabbits would ignore. Get down to floor level in the room your rabbit uses and look for the route he sees: the shadowed gap under a sofa, the space beside a bookcase, the opening behind a washing machine, and the corner where skirting boards do not quite meet. If his head and shoulders could work into a space, treat it as an exit until you have blocked it properly.
Work around the room slowly and press each barrier after fitting it. A dwarf who leans, digs, and pushes during play will find a panel that only looks secure.
Close the Gaps He Can Actually Use
Block under-furniture spaces with solid boards or tightly fitted blockers that cannot be chewed through quickly or dragged aside. Cover the gap at the bottom of the exercise-room door, secure cupboard doors he could nose open, and check that a playpen joins in a complete, latched loop with no widened corner. Keep the pen away from furniture he could use as a launch step over the top.
Move toiletries, cleaning bottles, medicines from other pets, and small objects he could swallow out of any cupboard he might enter. A successful escape inside the house can become a poisoning or blockage emergency even when he never reaches outdoors.
Protect Cables, Corners, and Chew Targets
Netherland Dwarfs explore with their teeth, and a live cable behind a television is an invitation. Run cables inside hard conduit, lift them off the floor where you can, and block the tangle behind entertainment units completely rather than relying on a bitter spray alone. Protect exposed corners and skirting with guards in his exercise area, and give him safe wooden chew pieces and hay-based toys in several spots so the approved target is always closer than your furniture.
Check the guards weekly. A chewed-through cover can expose both the cable and a new squeezing route behind the unit it was hiding.
Make Doors and Visitors Part of the System
Most escapes start with a human moment: a front door held open for shopping, a child leaving the pen gate unlatched, or a visitor who does not know the rabbit is loose in the hall. Keep your dwarf in his secured pen or a closed rabbit-proofed room before answering the door, and make one clear household rule that his area is never opened while an outside door is open. Put a small reminder on the pen latch if guests or children help with care.
When he travels to another room, carry him securely against your chest with one hand supporting his hindquarters, or use a closed carrier for longer trips through the house. A startled dwarf can kick and leap from loose arms near a stairway.
Do a Daily Thirty-Second Sweep
Before free-roam time, glance at the pen joins, the door blocker, the under-sofa barriers, and any cable cover you know he works on. After play, count him back into his enclosure rather than assuming the quiet bundle in the hay is him. If he does get out, stay calm, close outside doors, block the room he is believed to be in, and let hay and a familiar treat box coax him out instead of chasing him deeper behind appliances.
