About This

• PERFECT SIZE FOR LARGE DOGS & MULTI-PET HOMES: Designed with a spacious 17.3" x 9.45" flap opening, this large dog door is ideal for pets up to 100 lbs. Perfect for busy households where dogs need the freedom to go in and out independently. Fits doors and walls 1.02"–2.36" thick. Be sure to review the installation guide and video before setup for the best fit.
• DOUBLE FLAP DESIGN FOR ALL-WEATHER PROTECTION: Unlike ordinary single flap dog doors, the Petcoming dual-flap system delivers enhanced insulation, wind resistance, and noise reduction. Strong magnetic flaps help block cold drafts, rain, heat, and outdoor odors while creating a quieter close—ideal for stormy weather, winter months, and energy-conscious homes.
• BUILT FOR DAILY USE: Made from reinforced outdoor-grade polymer, this durable dog door is engineered to handle active pets, repeated impact, and changing weather conditions. The thicker frame construction resists cracking and warping better than standard plastic pet doors, making it a reliable long-term solution for indoor or exterior use.
• SAFE, SECURE & PET-FRIENDLY: Give your dog the freedom they love while keeping control when needed. The included locking closing panel helps restrict access during nighttime, travel, or bad weather. Also includes 2 PET FIRE RESCUE STICKERS to help alert firefighters and first responders that pets may be inside the home alone.
• FAST INSTALLATION: Our pet door is designed for quick and simple installation on a variety of indoor and outdoor surfaces. We include everything you need—a cutting template, screws, an instruction manual,and more. Just follow the step-by-step guide or installation video, and you’ll have your dog door set up in no time!
• EXCEPTIONAL SUPPORT: At Petcoming, we stand by our products and your satisfaction. Enjoy 24/7 customer support ready to assist you anytime. Plus, we offer free replacement flaps if yours ever gets damaged or falls off—because we believe in delivering not just quality, but peace of mind
