Buying Guide

Match flap size to your dog

Measure shoulder width and height to choose a flap or opening size that lets your dog pass comfortably without squeezing

Check frame compatibility

Confirm the product fits your door type—wood, metal, PVC, sliding screen, or telescoping frames—before buying

Choose material for climate

Vinyl and dual-pane or airseal flaps offer better insulation, while single-pane vinyl is lighter for mild climates

Look for easy replacement designs

Replacement flaps and telescoping frames simplify installation and reduce the need for cutting new openings

Consider security and magnetic closure

Magnetic or weighted closures help keep doors sealed against drafts and prevent unwanted entry
