Wood Fitting Dog Doors

Wood Fitting Dog Doors

A timber back door is the easiest home a dog door will ever have — no glazier, no glass, just a jigsaw, a screwdriver and an afternoon. Dogwalk® wood fitting dog doors screw directly into wooden doors and panels, and this range carries the tallest flap we make: 270 mm wide × 320 mm high on the full-size model.

Two sizes, two body styles. The full-size door suits panels from 5 to 36 mm thick. The small dog door, with its 180 × 240 mm flap (width × height), comes as a slimline for standard doors (11–30 mm) or as a tunnel version that lines openings up to 52 mm — thick doors and even walls. Both come in white or brown to sit naturally against painted or stained timber, and every door locks four ways.

Dog better suited to glass? The glass fitting dog doors cover sliding and French doors. Not sure which flap your dog needs? Our sizing guide covers the measurements, the size-by-breed guide gives you a starting point, and two minutes with the Find Your Fit tool settles it.

Wood Fitting Questions, Answered

Can I install a wood fitting dog door myself?
Yes — this is the DIY-friendly range. You cut the opening with a jigsaw using the supplied template, then the door screws into place, lining the cut as it goes. Step-by-step instructions come in the box and as a downloadable guide on every product page.
What’s the biggest dog these doors handle?
The full-size wood fitting door has a 270 × 320 mm flap (width × height) — the tallest in the Dogwalk® range — suited to large dogs. Check your dog’s chest width against the flap width and their shoulder height against the flap height before ordering.
Slimline or tunnel — what’s the difference?
Thickness. The slimline suits standard timber doors from 11 to 30 mm. The tunnel version lines openings from 11 up to 52 mm — thick solid doors, and walls — so the passage through is fully finished with no raw edges.
Will it weaken or ruin my door?
No — the frame lines and reinforces the cut opening on both sides, with a clean finished look. If you ever remove it, you’re left with a neat rectangular opening a carpenter can patch or a replacement door solves.
Does the flap keep weather and draughts out?
Yes — the flap closes onto a full brush seal with near-zero tolerance, and the body’s internal draft angles drain water away. UV-stabilised polycarbonate shrugs off the Australian sun without yellowing or hardening.
What if the flap wears out years from now?
You replace the flap, not the door — genuine replacement flaps for both wood fitting sizes are in our spare parts range and clip in within minutes.
