Find the Perfect Fit

"A pet door that’s too small is a safety hazard; one that’s too big is an energy drain. [span_0](start_span)Let's make sure your dog is comfortable from day one." Rob McDonald[span_0](end_span)

Measuring your pet is the most critical step. While we've seen thousands of dogs, every build is unique. [span_1](start_span)[span_2](start_span)Follow these three steps to ensure your pet can pass through comfortably for years to come.[span_1](end_span)[span_2](end_span)

1

The Width

Measure your pet at their widest point (shoulders or hips). [span_3](start_span)Add 1 to 2 inches to this number.[span_3](end_span) [span_4](start_span)Your dog should walk through without brushing the sides.[span_4](end_span)

2

The Height

Measure from the floor to the top of the shoulders (the withers). [span_5](start_span)[span_6](start_span)The top of the flap must be 1 to 2 inches above the shoulders.[span_5](end_span)[span_6](end_span) Do not measure to the head.

3

The Step-Over

This is the threshold height. [span_7](start_span)[span_8](start_span)Ideally, it should be no more than 1/3rd of your dog's shoulder height to ensure easy access as they age.[span_7](end_span)[span_8](end_span)

The "Cardboard Test" (Pro Tip)

Cut the intended opening dimensions into a piece of cardboard. [span_9](start_span)[span_10](start_span)Hold it in a doorway at the target height and call your dog through with a treat.[span_9](end_span)[span_10](end_span) [span_11](start_span)[span_12](start_span)If they hesitate, you need a larger size.[span_11](end_span)[span_12](end_span)
