Best Dog Doors for German Shepherds: 6 Picks and a Size Guide
The AKC lists a male German Shepherd Dog at 24 to 26 inches tall and 65 to 90 pounds, and a female at 22 to 24 inches and 50 to 70 pounds. The AKC article on choosing a dog door says “Large dogs must fit through comfortably.” The six doors below each have an Amazon listing that gives its own size, and the first table puts the flap openings and weight ranges side by side.
The AKC describes dog doors as “protected openings built into an existing door or outside wall of your house” that “allow your dog to access your yard and return to the house without your assistance.” For pet parents who are tired of letting a dog out and in all day, that is the appeal. The sections after the picks cover size, where each door installs, insulation, locks, yard safety, and teaching a dog to use the flap.

Top Picks for German Shepherd Dog Doors
PetSafe XL Freedom Door
The listing sells this door in Extra Large and says it is “Designed for pets up to 220 lb,” with a flap opening of 13 5/8 inches wide by 23 5/8 inches high. The frame is paintable plastic, and the listing says the door suits “interior or exterior wood, PVC, metal and paneled human doors between 1/16 inches and 2 inches thick.” A cutting template and step by step instructions come with it.
The listing says the snap on closing panel “allows you to control your pet’s access and keep stray animals out of your home.”
SmarketBuy Aluminum Dog Door
The listing gives this door a flap opening of 14.4 inches wide by 24.5 inches high and a cutout of 14.6 by 25 inches in the door or wall, and says it is “suitable for pets up to 220 pounds.” The title calls it an aluminum frame pet door with a sliding lock panel, and the listing says it fits doors or walls over 1.25 inches thick.
On the lock, the listing says the “security sliding lock design” can “keep you and your family safe at night or when you are not home by keeping other animals out of the house.” On the flaps, it says “Weatherproof magnetic closure and two UV-resistant flaps, suitable for different climates and provides energy efficiency.” A cutting template, instructions, and mounting hardware come with it.
MIAOTONG 3-Flap Extra Large Dog Door for Wall
This is a wall door. The listing gives an “Oversized flap opening” of 13 1/8 inches wide by 24 7/8 inches high, a frame of 17 3/4 by 28 3/8 inches, and says “pets can weigh up to 220 lbs.” It fits walls 3 9/16 to 6 11/16 inches thick, and a cut-out template with installation guides comes with it.
For weather, the listing says the door “adds an extra insulating flap to the double flap design to withstand harsh weather conditions from -20°F to 120°F” and has a “highly efficient brush seal.” The title lists a sliding lock panel.
Ideal Pet Door
The listing sells the Super Large size of the Ideal Designer Series, with a 15 by 20 inch flap, and gives the “Recommended weight range of pet: 91 to 120 Lbs.” The cutout is 16.5 by 22.25 inches, the frame fits doors from 1 1/4 to 2 inches thick, and the listing gives an “Average install time: 20 minutes.” It says the door “Includes a lock-out-slide to keep your pet in or out.”
What we really liked about this door is the impact-resistant frame; it feels sturdy and capable of withstanding whatever our pup (or the weather) throws at it. Plus, the vinyl flap having patented edges means no worrisome warping on those hot summer days or cold winter nights.
PetSafe Extreme Weather Aluminum Door
The listing sells the X-Large size, and its title calls the door an aluminum dog door with a “3-Flap Insulated” design. PetSafe’s own product page gives the X-Large a flap opening of 13 3/4 by 23 3/4 inches and a pet weight of “Up to 220 lb.” The listing says it installs in doors “1 1/2 in - 2 in thick.”
The listing says the door is “Insulated to block 3 times more thermal energy than a standard pet door, and includes adjustable, flexible flaps with a magnetic seal.” It describes the frame as “Durable metal frame has reinforced aluminum corners,” and says a “Sturdy slide-in closing panel controls your pet’s access and keeps stray animals out.” The listing adds “1 year warranty.” Read more about energy-efficient design.
Baboni X-Large Pet Door for Walls
The title calls this a pet door for walls with a steel frame, a telescoping tunnel, and an aluminum lock, with the size given as “Pets Up to 220 Lb.” The listing gives a flap opening of 13 19/64 inches wide by 23 19/32 inches high. The tunnel fits walls 4 3/4 to 7 1/4 inches thick, and the cutout in the wall is 14 9/16 by 25 inches.
For weather, the listing says “Seal out the elements and maintain indoor comfort with the advanced three-flap design featured.” It also says the door comes with “one metal closing panel.” Read more about large breeds.
How Big a Dog Door a German Shepherd Needs
The AKC article on choosing a dog door says “Be sure that the door will accommodate the size of your dog,” and “Large dogs must fit through comfortably.” A trainer writing for the AKC, Sassafras Patterdale, CPDT-KA, CTDI, says the door should be “a safe and appropriate size for your dog,” and that “A dog door that is too small could be frightening or even dangerous for a dog if they were to get stuck going in or out of the dog door.”
Each maker states its own flap opening and weight range in the first table. The AKC height and weight in the lead are the breed numbers from the AKC page.
Door Thickness and Where Each Door Installs
| Door | What the listing says it installs in |
|---|---|
| PetSafe XL Freedom Door | Doors from 1/16 to 2 thick |
| SmarketBuy Aluminum Dog Door | Doors or walls over 1.25 thick |
| MIAOTONG 3-Flap Extra Large Dog Door | Walls 3 9/16 to 6 11/16 thick |
| Ideal Pet Door, Super Large | Doors from 1 1/4 to 2 thick |
| PetSafe Extreme Weather Aluminum Door, X-Large | Doors 1 1/2 to 2 thick |
| Baboni X-Large Pet Door for Walls | Walls 4 3/4 to 7 1/4 thick |
The AKC says “The most common and usually least expensive type of dog doors are simple flaps that cover openings made in your current door or wall.” All six picks are flap doors. For a sliding glass door, the AKC says “Floor-to-ceiling panels are easy to insert in a sliding door opening and offer an excellent alternative to making holes in your wall or door. These inserts are an especially great option for those who are renting.”
Frame Materials
The six listings name their frames in different materials. The PetSafe XL listing says “paintable plastic frame,” the PetSafe Extreme Weather listing says “Durable metal frame has reinforced aluminum corners,” and the Ideal listing says “impact-resistant plastic frame.” The SmarketBuy title says aluminum frame, the MIAOTONG listing says “premium aluminium dog door,” and the Baboni title says steel frame. Read more about heavy-duty materials.
Insulation and Air Leaks
The AKC says “It’s important to look for dog doors made of materials that insulate your home from cold or hot temperatures, rain, and snow,” and “Some versions have double flaps or magnetic seals to provide more protection from outside temperatures.”
ENERGY STAR says “Sealing air leaks around your home and adding insulation can help your home be more comfortable and energy efficient and provide up to a 10% savings on your annual energy bills.” Its next line is “Simple fixes include installing weather stripping on doors and caulking around windows.” Read more about best insulation.
The PetSafe Extreme Weather, MIAOTONG and Baboni listings name a 3-flap design. The SmarketBuy listing describes two flaps. Each listing words its own temperature or weather claim, and the quotes under each pick give them as the maker wrote them.
Locks and Security
The AKC says “Some doors have locks and electronic timers. These features allow you to secure the door at night or when you’re on vacation.” It also says “Consider installing your dog door away from doorknobs or window latches that can be opened if someone reaches in.”
The PetSafe XL listing describes a snap on closing panel, the PetSafe Extreme Weather listing a slide-in closing panel, and the Baboni listing a metal closing panel. The SmarketBuy and MIAOTONG list a sliding lock panel, the Ideal lists a lock-out-slide, and the Baboni title lists an aluminum lock.
Yard Safety Before the Door Goes In
The AKC says “If your dog is going to be outside unsupervised, your yard must be escape-proof, your plants mustn’t be toxic to dogs, and your pool or pond must be fenced and inaccessible.” The AKC trainer says “Your dog door should only open into a dog run or fenced area of your yard that is securely enclosed.”
The trainer also says “especially unsupervised dogs are very vulnerable to the elements, conflict with wildlife such as coyotes, raccoons, and birds of prey, as well as harassment from people who may walk past your yard.” On wildlife, the AKC door article says “a dog door could allow unwelcome surprises into your home.” On children, it says “If you have toddlers who could copy your dog and exit through a dog door, you may want to wait until they’re older to install one.”
Teaching a German Shepherd to Use the Door
The AKC says “All dogs aren’t automatically drawn to use dog doors, so expect to put in some time training your dog how to go out and come back in without your help.” The trainer says “You should never push your dog to use the dog door or scold and punish your dog for not using it.”
The trainer lists six steps. Step 1 is “First show your dog the dog door and pair the sight of the door with treats and praise.” The last step ends with “Ensure that your dog is very comfortable and confident moving back and forth through the dog door before leaving them unattended.”
The AKC lists reasons a dog door may not fit, among them housetraining, wildlife, and a dog that barks at passersby. It adds that dog doors “shouldn’t replace the time you spend with your dog playing fetch in the yard, taking walks together, and doing positive reinforcement training.”
Warranty and Support
The PetSafe XL listing says “Our pet product experts are here to help you and your pet and are available by phone, email or chat if you have any questions.” The PetSafe Extreme Weather listing says “1 year warranty.” The Baboni listing has an “AFTER-SALES GUARANTEE” line, and the SmarketBuy listing invites questions about installation or the product.
