What matters most for small dogs
A dog door for a small breed needs a flap sized to their height and width, low enough that they can step through without jumping. Measure your dog’s shoulder height and chest width, then choose a flap with the step-over height as low as practical. A flap that is too big wastes heat and feels insecure to a little dog.
Look for a soft, lightweight flap your small dog can push easily, ideally with a magnetic seal and weather stripping to keep draughts out. A locking panel lets you secure the door at night. Natural or low-odour materials suit homes where the door sits in a kitchen or utility area. Introduce it gently with treats so a timid small dog learns the flap is safe to nudge through.
