    Though all dog doors do their very best to keep unwanted pests out, the High Tech Pet Electronic Door is by far the best choice if you’re worried about unwanted animal friends dropping by for a visit. This sensor-triggered dog door uses a lithium battery-operated collar to trigger the door and let your dog out when he’s ready to do his business. The directional operation is created to open only when your dog is directly approaching the door, not when he is sleeping or nosing around nearby. The door measures 12” x 16” and works for dogs up to 100 pounds. The four-way access control allows you to switch modes from in-only, out-only, both ways or fully locked as needed.

    Though this electronic dog door has a higher price tag than the standard doors on our list, owners say it’s easy to install and well worth the cost for the security it offers.
