Can other animals get in if they follow close behind my dog?

This is known as tailgating. While both doors lock immediately after your dog passes through, a very determined stray could theoretically slip in before the door latches closed. However, the quick-relock mechanisms on both models make this extremely rare in practice.

Will the SureFlap work if my dog's microchip has migrated?

If your dog's microchip has migrated down their leg or deep into their shoulder, the SureFlap sensor arch might struggle to read it. You can test this before installation by waving the door over your dog's back to see if the latch clicks open.

Can I install the PetSafe SmartDoor in a brick wall?

Yes, but you will need to purchase a wall installation tunnel kit separately. Wall installations require extra framing and sealing to ensure moisture does not seep into your home's wall cavity.

How long do the batteries last in these smart doors?

The SureFlap batteries typically last 6 to 12 months with normal use. The PetSafe SmartDoor batteries usually last 3 to 6 months, though using the optional wall power adapter removes the need for batteries entirely.

What happens if the batteries die while my dog is outside?

Both doors feature low-battery indicator lights to warn you weeks in advance. If the batteries do die completely, the doors default to a locked state for security, meaning your dog would be locked out until you replace the batteries.
