Description is below picture.
Dogloo Door X Large. Frosted plastic door flap for XLarge (old Large) Dogloo and Dogloo XT. Fits only the Igloo-style original Dogloo, and does not fit either the Indigo or Dogloo II houses.
Please note that the door flap does not cover the entire door opening as this allows for the use of a pad and keeps the house from over heating.
Size of Flap is 19 x 18.8 inches
Please measure your door opening before placing order, as in the past few years the manufacturer has re-named their dog house sizes.
