Key Buying Factors
Mounting Type
Choose between door-mounted or wall-mounted based on your home's construction. Door-mounted models are easier to install, while wall-mounted provide more flexibility in placement and can be larger.
Weatherproof Seal
Look for dual-flap or magnetic seals that prevent drafts, rain, and snow from entering. The MaxSeal line features our team's favorite weather-resistant designs.
Flap System
Single-flap is simpler and more flexible; dual-flap adds insulation and better security. Consider your climate and how much energy efficiency matters.
Locking Mechanism
Sliding or twist locks allow you to restrict pet access (e.g., keep pet in at night). Some models feature dual locks for added security. We recommend models with easy-to-use locks.
Pet Size Compatibility
Measure your pet's height and width at the shoulder. Check the actual opening size of the pet door, not just the overall frame. Our picks include small to extra-large options.
Durability & Materials
Reinforced frames, impact-resistant flaps, and UV-stabilized materials ensure longevity. Security Boss products use high-quality plastics and aluminum components.
Care, Cost and Maintenance
Clean Flaps Regularly
Wipe flaps with a damp cloth to remove dirt and paw prints. Use mild soap if needed. Avoid abrasive cleaners that can scratch the plastic.
Check Seal Integrity
Inspect weatherstripping and magnetic seals every few months. If gaps appear, replacement strips are often available from the manufacturer.
Lubricate Hinges and Locks
Apply a silicone-based lubricant to moving parts yearly. This prevents sticking and ensures smooth operation in all weather.
When measuring for a pet door, always measure your pet's width at the widest point (usually hips) and add at least 1-2 inches for comfortable passage.
