10 Best Metal Dog Doors 2025 in the United States

The Baboni 3-Flap Pet Door is designed for large dogs and cats up to 220 pounds, making it a solid choice if you have bigger pets. Its size is generous, with a flap opening around 13.3 by 23.6 inches and a frame that fits wall thicknesses between about 4.75 and 7.25 inches, so it works well for many homes with standard wall sizes. The door is made from a metal frame with a steel and aluminum alloy, which promises durability and strength, plus it features a magnetic aluminum lock for secure closure. This helps keep your home safe while letting pets in and out without assistance.

One smart feature is the three-flap design, which creates a good seal against weather, helping to keep your house insulated and energy efficient by blocking drafts. Installation is meant to be straightforward with detailed instructions and a cut-out template included, though it does require cutting into a wall, so some DIY comfort or professional help might be needed. At about 22.5 pounds, it’s sturdy but manageable to handle.

Some users might find the metal construction a bit heavy or complex for quick fixes, but it adds to long-term durability. The door’s design suits pet owners who want a secure, weatherproof way to give their larger pets freedom to come and go, especially if energy efficiency and home security are priorities. If you have thinner walls or smaller pets, this model might be less ideal due to its size and installation requirements.
