Trixie 2-Way Locking Dog Door for Medium to X-Large Dogs - Quiet

Our review of the Trixie 2-Way Locking Dog Door finds it best suited for households with medium to extra-large dogs that need independent access to a yard or utility room. The single biggest reason to buy is its combination of a silent, flexible transparent flap and a lockable panel that lets owners control access while keeping the door quiet for the household. Assembly is straightforward and the design balances visibility for pets, weather protection, and security without excessive complexity.

Key Features

• Right fit for medium to large dogs: The door is sized to accommodate dogs up to about 95 pounds, making it appropriate for many M to XL breeds.
• 2-way access with lock: A removable metal rear panel lets owners switch between free access and locked mode to keep out unwanted guests or bad weather.
• Silent transparent flap: The anti-scratch plastic flap closes quietly so it will not disturb people in the house while remaining durable for daily use.
• Easy installation: Includes a cutting template, detailed instructions, and hardware to fit interior and exterior doors between 0.5 in and 1.25 in thick.
• Extendable tunnel element: A tunnel piece extends the depth to fit doors with thickness from 0.75 to 1.25 in for a secure installation.

Who It's For

This pet door is ideal for owners of medium to extra-large dogs who want a practical, budget-friendly way to give pets more freedom to go outside for potty breaks and play without waiting for someone to open a door. It works well on garage doors, laundry room doors, or backroom doors where a durable plastic frame and metal base are preferred.

Owners who need a heavy-duty, weatherproof or highly insulated pet door for extreme climates, or who require a custom-fit solution for very small door cutouts, should consider specialty models. Also, those with very small dogs should choose a smaller flap size instead.

Pros & Cons

Pros

• Easy to install with included template and hardware so most DIYers can fit it quickly.
• Quiet, flexible flap that reduces noise and shows good day-to-day durability according to owners.
• Lockable rear panel provides extra security when pets should not go outside.
• Good value for money and well sized for mid to large dogs.

Cons

• Some customers note concerns about long-term durability of the flap or seal with heavy use.
• Not designed for ultra-thick doors or for very small dog breeds without selecting a smaller model.
