Buying Guide

Match flap size to your dog

Measure shoulder width and height and choose a flap or panel size—options include small 5x7 flaps and XL 10.25" x 15.75" panels—to ensure safe, comfortable passage

Consider closure type

Magnetic closures add a simple seal to reduce drafts and keep the flap more secure; look for models that specify magnetic or airseal features for improved insulation

Screen-door protection for rentals

If you use a screen or sliding door, a grille or screen-door protector offers reinforcement without full-door modification, useful for preventing pet damage

Material and durability

Steel grilles and reinforced panels provide longer-lasting protection against chewing and scratching compared with thin plastic flaps

Energy efficiency and sealing

Multi-panel or airseal flaps reduce drafts and heat loss better than single-panel flaps—look for products labeled airseal or with layered construction
