Engineering a custom portal for a 125-pound Newfoundland
In short: Watch how experts navigate the structural challenges of installing a pet door when the ideal location is unavailable. This project demonstrates how to modify a load-bearing wall to accommodate a large dog without compromising the home's integrity.
Because the Arlington family's 125-pound Newfoundland, Soleil, could not have a door under the window due to outdoor stairs, the team had to create a custom rough opening in the mudroom wall. This required cutting out existing studs and constructing a new header supported by a jack stud to safely carry the weight of the structure above.
The installation involves precise exterior finishing, including a bottom cut pitched two inches lower to ensure water runoff. The final result is a saloon-style door kit designed specifically for a large breed's shoulder height, balancing functional pet access with proper home construction standards.
