Power Pet PX-2DM Large Door Mount

In this power pet px-2dm large door mount review, the verdict is clear: the Power Pet PX-2DM from High Tech Pet is the best electronic dog door for large dogs in our 2026 guide, ranked number two of nine. At $474.99, it uses a motorized aluminum panel with a 12.25 by 16 inch pet opening, and High Tech Pet rates it for pets from 30 to 100 pounds. That size clears a Labrador or a German Shepherd without the head ducking that flimsier plastic doors can force. Amazon shoppers give it 4.4 stars from 60 ratings, the highest average among the large door mounts we compared. Because the door opens only for a pet wearing a genuine High Tech Pet MS-5 collar, strays and wildlife cannot trigger it.

Day to day, the Power Pet PX-2DM opens automatically as your dog walks up, so no nose push is needed. In practice, directional sensing keeps the panel from firing when your pet wanders past the doorway or rests beside it. The aluminum frame matters more here than on a small door, because a 100 pound dog leans on a panel far harder than a 20 pound one. On top of that, the control panel offers four modes (In Only, Out Only, In & Out and Locked), which lets you keep a dog inside during a storm or shut the door at night. A steel dead bolt locks instantly after each close, and the safety system reopens the panel if it meets an obstruction.

The $474.99 price is high, yet it matches the other premium picks in our guide for large dogs. Compared with the medium PX1-WIFI, you pay roughly the same money for a taller, sturdier opening, so owners of small dogs gain nothing here. Meanwhile, the smaller PX-2 has a longer ratings history, while this large model has only 60 Amazon ratings, which means durability data is thinner. Even so, a 4.4 star average plus the aluminum build justify the cost for a big dog that needs a wide, solid opening. Skip it if your dog weighs under 30 pounds, or if you will not use a genuine MS-5 collar, because the performance warranty depends on authentic High Tech Pet transmitters. If your dog runs 30 to 100 pounds and your door is up to 2 inches thick, this is the one to order.
