  • Free and safe!
Size: Medium
This 3-piece steel dog door is literally made for it! Installed underneath the door of your home, it is just the right height and width. The three piece door design makes it very comfortable for your little one to get in and out without having to squeeze sideways. The steel frame is sturdy and feels like it will last for years. What reassures me the most is its extreme weather protection and insulation design, so no cold winds blowing directly in the winter and not too much interior temperature loss in the summer. The sliding lock panel design is user friendly and can be locked completely when needed to prevent the dog from wandering off. ... show more

  • A super practical dog door, a blessing for little dogs!
Size: Small
This three wing steel puppy door is really great! The material is sturdy and the sliding lock panel is very safe. Especially suitable for small dogs, with a maximum weight capacity of 12 pounds. What satisfies me the most is its insulation design, which can maintain indoor temperature regardless of extreme cold or heat. The telescopic tunnel is also easy to adjust and install. My little dog is now free to enter and exit, no longer needing to be held. I sincerely recommend it to friends with the same needs! ... show more

  • Dogs love it!
Size: Large
I bought this pet door for my mom and it’s been such a great purchase. I really like that it has three flaps, which makes it a better fit for a variety of door types. It’s super flexible and feels more secure than some of the other options we looked at. Installation was really easy. It didn’t take long at all, and it was straightforward enough that we didn’t need any extra tools or help. I totally forgot to snap a picture before I left, but I’m going to try to get one from my mom so I can update the review. Her dogs have been using it constantly, and it’s holding up really well. The magnetic closure is sturdy and clicks back into place every time, so no drafts or flapping around. I’ve been so happy with how this one worked out that I’m planning to order a smaller version for my cats. Highly recommend! Value for money: Great value for money! Durability: Holding up well! Flaps seem strong! Fit: Seems very sturdy in place! Fit her door easily. Flap closure: Flap closure is great! Magnetic closure is holding up well. Doesn't seem to be letting any air escape! ... show more

  • Trustworthy!
Size: Small
This steel dog door with a metal sliding lock panel allayed my concerns. The locking panel completely seals the doorway and is very strong, preventing your dog from accidentally running out or strangers from entering through the dog door. The three-piece door leaf design is not only windproof but also adds security. The steel frame is sturdy and reliable, and looks substantial. The telescopic tunnel is easy to install and can adapt to different door frames. ... show more

  • Durable and weather-resistant dog door for larger breeds
Size: Large
We installed this dog door for our 85 lb Labrador, and it's been performing great so far. The triple-flap design really helps with insulation—there’s much less draft compared to our old one, and it feels solid and secure. Installation took a bit of time but was manageable with the instructions provided. The telescoping tunnel made it easier to fit through our thick door. The sliding lock panel is a nice touch too—it gives peace of mind when we’re not home. What I appreciate most is that the frame is made of steel, not plastic, so it feels sturdy and long-lasting. No rust issues either after a few rainy days. It’s definitely a good fit for homes that experience more extreme weather. Highly recommend if you have a large dog and want something more durable than the average pet door. ... show more

  • Complete and total failure.
Size: Large
Wow, this might be the most disappointed I’ve been with any Amazon purchase. This door has plenty of good reviews and I had high expectations of finally solving having to open a door for a dog that loves being on the other side of a door. But once I starting actually installing the door it was all downhill. The hardware included must have been for some other piece of equipment all together, it made no sense for the dog door. It was all stuff for mounting in drywall. Since I didn’t have the right size bolts on hand I had to drill out the frame to fit a slightly larger bolt. I finally get the door installed and try it out… the flaps don’t come even close to sealing. I mean a good 1/2 to 1 inch gaping gap. They hang up in the side insulating brush weatherstripping. If I hold two of the flaps out of the way and only use a single flap it will sort of close maybe 1 out of 4 tries. Completely useless, and now I have to reap turn this thing and deal with a huge hole in my door. Not a happy camper here. Total disappointment. I’d get better functionality by just taping the slab of wood I cut out of the door and let that swing loose. ... show more

  • sturdy and durable
Size: Medium
The steel frame and three baffle designs with felt in the centre completely block the cold wind in winter and stop the loss of cold air inside in summer. That metal sliding locking panel is sturdy enough to seal the door completely when not in use for a secure feeling. My golden hair adapted very quickly, and now it goes in and out by itself when it wants to play in the yard or go back to the house for a drink of water, so I don't have to chase after it to open the door anymore. The installation process was slightly laborious, but the results really stand up to the effort, especially for homes that focus on indoor temperature and energy efficiency. ... show more
