What matters most for large dogs

An electronic pet door for a large dog needs a generously sized flap and a frame rated for the weight of a big body pushing through. Measure your dog’s shoulder width and step-over height carefully, because a door that is too tight makes them hesitate or duck awkwardly. The electronic part, usually a microchip or collar-tag reader, must respond quickly so the panel unlocks before a fast-moving large dog reaches it.

Portable or temporary-fit electronic doors suit renters and travel, often mounting in a screen, sash, or panel insert rather than a permanent wall cut. For a large breed, check the locking mechanism is robust enough not to be nudged open by sheer body weight, and that the motor is rated for heavy use. A reliable seal keeps draughts out around the bigger opening. If your dog is nervous of the motor sound, introduce the door slowly with treats so they learn it is safe.
