PetmateIndigo Dog Door

Works well and fits with the Igloo. Was a little difficult to install but once it was on we had no problems.Update: 2/27/18While it worked well and was difficult to put on I noticed it was a little stiff when it was attached at the top. Today the door was broken off and on the ground. The points where the break happened were right where the holes to attach are.Thankfully we also have a heating pad and we are pretty much out of our cold season.

Doesn’t cover the whole opening

Seems to work ok and once I got it in place our outdoor cat has no trouble getting in and out of the Dogaloo. BUT MAN! What a pain getting it in place. It might help if came with this thing already attached or at least if I didn't have to pound in the little pilot holes myself - with the little nails it wasn't easy, but I got it done, eventually.

I actually used Dr laundry shoot worked perfect.

Too small and my dog would not enter dog house if installed.

I own the extra large igloo. door is a few inches short and narrow at the bottom

I liked everything until a few weeks latter my beagles decided to pull them off.

Fit is not perfect but works helping to keep the wind and cold air out. She seems to be more comfortable during her hibernation.
