Review: Love my new door does not let the weather inside! - I was worried that the three flaps that they go in and out might scare my little Maltipoo the two big dogs were pretty easy they hesitated but adapted well!

It also is nice the wind doesn’t blow the flaps to let the cold air inside. ### ⭐⭐⭐⭐⭐ EXTREMELY SATISFIED *by R***R on May 20, 2026* I PURCHASED THIS BACK IN JULY OF 2025. HAD NEW DOORS REPLACED IN JANUARY AND PUT THE DOGGIE DOOR IN. I HAD ISSUES WITH THE SCREW HOLDING THE FLAPS IN PLACE. THEY STARTED TO LOOSEN AND THEN WOULDN'T TIGHEN AT ALL. I CALLED THE SUPPORT TEAM LOOKING FOR ADVICE OR A SOLUTION. I DIDN'T HAVE MUCH EXPECTATION AND TO MY SURPRISE THEY OFFERED TO SEND ME A REPLACEMENT DOOR. WASN'T READY FOR A COMPANY THESE DAYS TO STAND BEHIND THEIR PRODUCT. I'LL BE HONEST I'M A BIT SHOCKED AND PLEASANTLY SURPRISED.
