    Great Pet Door

    Posted by Mike in Dallas on Apr 11th 2023

    This is the best pet door on the market. We just purchased our second one for a new home. We use the custom-made version to get the perfect dimensions for our two collies. The quality of the materials is exceptional, and even after several years of use, there is very very little wear and tear.
