Excellent Quality
This pet door was very easy to install and arrived promptly. Looks great and my cats love it!

Perfect Solution
The MaxSeal Door Mount is the perfect option for our cat to have free range over the yard while we are out. The cat door provides great insulation. After we cut the hole in the door, installation took moments.

What a pet door!!
I just wanted to let you folks know what a great job you are doing. My maxseal door is by far the best door I have ever owned. I spent years using the cheaper doors that are out there. I have never seen a dog door work better through a harsh Montana winter than this one. I only with I would have found you sooner. Keep up the good work!

Great door!
I live out in the desert and have to run my AC for long stretches at a time. I wanted to keep my dog door, but it was just letting out too much of the cool air. I admit it was a cheaper model, but I didn't know any better. When a friend told me about the maxseal door, I was still skeptical. I just hadn't seen anything work well in the desert heat. I am happy to say, I was completely wrong. The maxseal door has been an absolute dream come true for us. Our three dogs have full access to the yard whenever they want, and we don't have to worry about the energy loss anymore. I completely recommend this door to anyone that is looking for energy efficiency within a dog door.

MaxSeal Pet Door | Door Model | Pet Door Review
The MaxSeal dog door is the best quality pet door I have ever seen. The framing is very rugged and does not easily twist like the average door on the market. My dual flap model always seals and keeps out wind, rain and snow. I have three large dogs that use the door all day, every day, and the door still operates like the day I installed it. The customer service from Moore Pet Supplies was knowledgeable and very friendly. I believe these guys know more about pet doors than anyone. I have recommended the MaxSeal to several of my friends, many of them already have purchased and are just as pleased. It is a very good feeling for me to purchase a quality product that is made in the USA. Good product, great service...I am very pleased.

Love my MaxSeal Pet Door
I was very frustrated with the amount of dog doors online and very leery of buying one of this price (almost $400) site unseen....but to my surprise it has been an awesome dog door. I have a GSP and a Jack Russell Terrier. They run in/out constantly and the door is so durable with all the magnets. We also get very high winds and the door stays closed and does not blow open! I highly recommend the dual flap. To keep it clean I just take a damp soapy cloth and it looks brand new again. I have had my door for over 6 months now and I am still very pleased with the MaxSeal door. I think you will be too.

Insulating
I was worried about putting in a pet door big enough for our Newfie. I thought it would be a drafty energy-losing hole. But we got the dual-flap model and I can't even feel a breeze or heat differential. It's awesome

Silver Mist Run / Dalmations Dog Door
We LOVE our 4 Dalmatians, 1 Beagle Basset & our MAXSEAL Double Flap Dog Door. No air leaks with sub-zero temps & 40 MPH winds. I researched the Internet for the BEST Dog Door available plus reviewing Consumer Reports. At the end of the day all roads led back to MAXSEAL for it's durability & quality. Pricey, but you get what you pay for. Moorepet's Customer Agents were wonderful, Door arrived quickly & installation was easy in my metal door. Installation Video helped. It took the Dalmatians about a week to learn and now go in and out at will. This Door is the BEST ! Moore-pet we will be a repeat customer. Thanks !

Great Dog Door
Just installed our MaxSeal Dog Door. When I took it out of the box I could tell this was build heavy duty! My 2 Huskies started running through as soon as it was installed. It seems as if they are changed dogs, they love checking on what is going on outside, just to run back inside. Temperatures have dropped and it has been windy the last couple of nights and I could not tell there was pet door there...great design, great dog door!
