Power Pet PXR Roll Up X-Large (WiFi)

In this power pet pxr roll up x-large (wifi) review, the High Tech Pet PXR X-Large ranks ninth of nine in our guide and carries the label Best for giant breeds. It lists at $789.99 with 4.2 stars from 23 Amazon ratings, so the feedback is positive but thin. High Tech Pet sizes this door for giant and large dogs, which makes it the pick for a Great Dane or a Mastiff. It is an X-Large, door mount unit, and it runs on genuine MS-5 ultrasonic collar transmitters. Simply put, it is a specialty door for one buyer: the owner whose dog needs more width.

In practice, the roll up design is the headline feature. The translucent resin panel rises when the collar triggers the motor, so your dog never pushes a heavy flap. For example, approach sensing activates the door before your pet reaches it, which cuts out scratching and barking. On top of that, dual range control sets entry and exit distances separately, from a few inches up to 20 feet. Four modes (Enter Only, Exit Only, Full Access, Locked) decide who comes and goes, which keeps stray animals outside. Meanwhile, Safe Return always lets your pet back in, so a mistimed lock cannot strand a dog outdoors. The composite frame weighs 24 pounds and accepts door thickness up to 6 inches, a figure that covers most insulated slabs.

Value is where this door asks for patience. At $789.99, it costs about $90 more than the large PXR in the same lineup, and both models share the same 23 ratings, so you are paying purely for extra width. Even so, few automatic doors list a giant breed size at all, and the 6 inch thickness tolerance means it fits thicker doors than most rivals. The honest caveat: if your dog is merely large rather than giant, the large PXR saves money and fits fine. Warranty coverage depends on using authentic MS-5 collars. If you live with a Mastiff or a Great Dane, though, this is the automatic dog door to buy.
