The BEST dog door money can buy
I bought my first Hale wall mount door about 12 years ago. It has been used many times a day ever since. No problems. I now have a larger dog and am replacing my Sheltie-size door with border collie size door. I didn't even bother looking at anything else besides another Hale door. They are well designed, built with high quality materials, they work like they're supposed to, and they last virtually forever.
