If you want your pet to move between rooms without waiting for you to open the door, a built-in pet opening can be a useful fix. The options below include pine screen doors with pet access, a prehung exterior door, and pet-door inserts you can install in a door you already own. Check the product type and measurements carefully: a screen door is not the same as a solid, privacy-providing interior door.

|---|---|---|---|
| AINLARRY 30" x 80" Pine Screen Door with Dog Door | Screen door with integrated pet opening | 30" x 80" slab; pet limit stated as under 120 lb and under 25" at the shoulder | Smaller openings and airflow |
| AINLARRY 32" x 80" Pine Screen Door with Dog Opening | Screen door with integrated pet opening | 32" x 80" slab; listing gives conflicting pet-weight information | A wider screen-door opening |

Our Picks: Best Interior Door With Pet Door Built In reviews
AINLARRY 30-Inch Pine Screen Door: Best Compact Built-In Option
This pine screen door combines mesh for airflow with an integrated dog opening. Its listed slab size is 30 inches wide by 80 inches high and 1.38 inches thick. The maker says it fits an opening of 32 by 81.5 inches without a jamb, or 30.3 by 81 inches with a jamb. Measure your actual doorway rather than relying on the door’s nominal size.
The pine frame is described as sanded and primed, so you can leave it as supplied or paint or stain it to suit your space. The mesh makes this a better fit for a porch, patio, or suitable interior location where ventilation matters than for a room where you need a solid, sound-blocking door. The product description lists a six-month door warranty.
The pet limit is stated as under 120 pounds and under 25 inches at the shoulder, but the product details also show inconsistent thickness measurements. Some owners have also raised concerns about fit or possible expansion. Confirm the dimensions and installation details with the seller before ordering, and consider how wood may respond to your home’s conditions.
Pros:
- Integrated dog access without cutting a separate opening
- Pine can be painted or stained
- Mesh allows airflow and visibility
- Pet size guidance is included in the description
Cons:
- It is a screen door, not a solid privacy door
- Some fit and expansion concerns make careful measuring especially important
Verdict: Choose this model if you want a 30-inch pine screen door with built-in pet access and have verified that its measurements suit your opening.
AINLARRY 32-Inch Pine Screen Door: Wider Screen-Door Choice
This 32-by-80-inch pine screen door offers the same general idea as the smaller AINLARRY option: a mesh panel for ventilation and a built-in pet opening. The listing gives a slab thickness of 1.38 inches and says the door fits openings measuring 34 by 81.5 inches without a jamb or 32.3 by 81 inches with a jamb.
The pine frame is listed as paintable or stainable, which gives you some flexibility if you want the door to match nearby trim. The screen construction is useful where air circulation is a priority, but it does not provide the same separation or privacy as a solid interior door.
Pay close attention to pet sizing before buying. The description says the opening is intended for dogs under 120 pounds and under 25 inches at the shoulder, while the product details give a maximum weight of 27 pounds. That is a significant conflict, so do not rely on the larger limit unless the seller confirms it. The listing also describes this model for storm-door use, so confirm it suits your planned location.
Pros:
- Wider slab than the 30-inch AINLARRY option
- Integrated pet opening and mesh screen
- Pine surface can be painted or stained
- Door dimensions and opening guidance are provided
Cons:
- Conflicting pet-weight limits need clarification before purchase
- Screen construction is not suited to every interior doorway
Verdict: Consider this wider screen door only if its dimensions fit your opening and you get clear confirmation of the pet-size limit.
National Door Company Steel Prehung Door: Best for an Exterior Replacement
This is a steel prehung entry door, not a standard interior door. It includes a frame, sill, hinges, weatherstrip, and pet door, so it may suit a homeowner replacing an exterior doorway rather than someone looking for a simple door slab. The door is primed for painting and has clear, double-pane tempered glass.
The listed door size is 32 by 80 inches, while the unit measures 33.5 by 81.75 inches. The suggested rough opening is 34 by 82.25 inches. It is a right-hand in-swing model, and the product information explains the handing from inside the home. Check that orientation before ordering; the lockset is sold separately.
The pet opening’s exact dimensions are not included in the supplied product details, so measure your pet and confirm the opening size before choosing this door. Some owners find the opening smaller than expected, though it may work for smaller dogs. Since this is a full prehung exterior unit, installation is a larger project than fitting a pet-door insert.
Pros:
- Prehung unit includes frame, sill, hinges, and weatherstrip
- Steel door arrives primed for paint
- Clear double-pane tempered glass provides visibility
- Pet door is integrated into the unit
Cons:
- Exterior entry door, not a typical interior door
- Pet-door opening dimensions are not provided here
Verdict: This is a practical candidate when you are replacing a compatible exterior entry door, but verify the handing, rough opening, and pet-door size first.
MIAOTONG Large Steel Pet Door: Best Heavy-Duty Insert
Unlike the first three picks, this product is a pet-door insert, not a complete door. It is designed to fit wood, PVC, and metal doors that are 1.2 to 2 inches thick. Its three-flap design includes a metal frame and a metal closing panel, and the listing gives a maximum pet weight of 100 pounds.
The flap opening measures 10 7/8 inches wide by 17 1/2 inches high. Use those measurements to judge whether your dog can pass through comfortably; weight alone does not determine fit. The product description says the insert arrives preassembled with a cutting template and instructions. Because installation requires cutting the existing door, measure and plan carefully before starting.
The metal construction and closing panel may appeal to households seeking a more substantial insert than a basic plastic frame. Still, it will not give you a built-in pet opening unless you install it into a compatible door, and the cutout will permanently alter that door.
Pros:
- Fits several door materials within the listed thickness range
- Three-flap design and metal closing panel
- Large listed flap opening
- Template and installation instructions are included
Cons:
- Requires cutting into an existing door
- Does not include the door itself
Verdict: Pick this insert if your door is within the thickness range and you want a large pet opening with a metal frame and closing panel.
Baboni Medium 3-Flap Pet Door: Best Insert for Smaller Pets
This medium-size pet door is another insert rather than a complete door. Its plastic frame is designed for doors between 1 3/8 and 1 31/32 inches thick. The flap opening is 8 1/4 inches wide by 12 1/4 inches high, and the stated pet limit is 40 pounds.
The three-flap setup uses two vinyl flaps with magnetic closure and an insulated flap in the middle. The product description says the design is meant to help reduce drafts. It includes a cutout template and step-by-step instructions, but installation still involves cutting the door. Check the frame and cutout measurements, not just the flap opening, before committing to a location.
Some owners find that pets need time to get used to the middle flap, particularly if they are accustomed to a single, see-through flap. That may be a factor for cautious animals. Compared with the MIAOTONG, this Baboni has a smaller opening and lower weight limit, which makes it a better match for smaller pets than larger dogs.
Pros:
- Three-flap design with magnetic closure on the outer flaps
- Fits a range of door thicknesses
- Cutout template and instructions are included
- Listed for dogs and cats up to 40 pounds
Cons:
- Requires cutting a hole in your existing door
- Some pets may need time to get comfortable with the middle flap
Verdict: Choose the Baboni if you want a medium insert for a smaller pet and your door matches its thickness and cutout requirements.
How to Choose a Door with Built-In Pet Access
Decide Between a Complete Door and an Insert
A complete door with an integrated pet opening can save you from cutting a separate hole, but it must match your doorway and the way you plan to use the space. The AINLARRY options are pine screen doors, while the National Door Company model is a prehung exterior unit. The MIAOTONG and Baboni are inserts that require an existing compatible door. Choose the product type before comparing features.
Measure the Doorway, Slab, and Frame
Measure the opening’s width and height, and note whether you are measuring with or without the jamb. For a replacement door, also check the slab thickness and the unit or rough-opening dimensions. Product listings may use different measurements for the slab, frame, and cutout, so compare the same measurement at each step. A small mismatch can prevent a door or insert from fitting correctly.
Check Pet Opening Size, Not Just Weight
Your pet needs enough clearance to walk through comfortably. Compare your pet’s height and width with the flap opening, and look for a shoulder-height limit if one is provided. Weight guidance alone cannot tell you whether the opening is tall or wide enough. The AINLARRY 32-inch listing has conflicting weight limits, so confirm the correct limit before ordering.
Match the Door to the Location
A mesh screen door supports airflow but offers less privacy than a solid interior door. A prehung exterior door involves a different kind of installation and is intended for an entryway. An insert can add access to a door you already have, but it requires a permanent cutout. Think about privacy, ventilation, weather exposure, and how much installation work you are prepared to take on.
Consider Flaps, Drafts, and Locking
Three-flap inserts may help limit drafts, but the extra layers can take some pets time to learn. If you need to restrict access, check what kind of closing panel or lock is included. The MIAOTONG listing specifies a metal closing panel, while the Baboni listing describes magnetic flap closure. These details affect everyday use, so choose based on your home and your pet’s comfort.
Confirm Handing, Hardware, and Included Parts
For a prehung door, confirm whether it swings in or out and which side has the hinges when viewed from the correct position. Check whether locks or other hardware are included; the National Door Company listing says locks are sold separately. For an insert, confirm that the template, instructions, and any closing panel are included as described.
Think About Finish and Upkeep
A pine screen door can be painted or stained, while the listed pet-door inserts use plastic or metal components. Consider how the material will look beside your trim and how much finishing work you want to do. For a door exposed to changing conditions, follow the maker’s care and installation guidance and confirm that the product is suitable for that location.
Frequently Asked Questions
Are these all standard interior doors with built-in pet doors?
No. The AINLARRY products are pine screen doors, the National Door Company product is a prehung exterior door, and the MIAOTONG and Baboni products are pet-door inserts. Confirm the product type before buying.
Can I install a pet-door insert in an interior door?
The MIAOTONG and Baboni listings describe installation in compatible doors, but you should check the door material and thickness against each product’s specifications. Installation requires cutting an opening, so make sure you are comfortable modifying the door.
How do I know whether the pet opening will fit my dog?
Compare your pet’s body size with the listed flap dimensions and any stated shoulder-height limit. Do not use the weight limit as your only guide. If the listing does not give the opening dimensions, ask the seller before ordering.
Which option is best for a larger dog?
The MIAOTONG insert lists a 10 7/8-by-17 1/2-inch flap and a maximum pet weight of 100 pounds. The AINLARRY 30-inch screen door description gives a pet limit under 120 pounds and under 25 inches at the shoulder, though it does not provide the flap dimensions here. Check the opening size against your dog, and confirm any conflicting specifications.
Do the AINLARRY screen doors provide privacy?
They have mesh panels designed for airflow and visibility, so they are not equivalent to solid privacy doors. They may suit a porch, patio, or appropriate interior location where ventilation is useful.
Does the National Door Company model include a frame?
Yes. The supplied details list a frame, sill, hinges, and weatherstrip among the included components. The product is right-hand in-swing, and locks are sold separately.
What should I measure before ordering?
Measure the doorway opening, jamb if present, door thickness, and the available space for the unit or insert. Also compare your pet’s size with the flap opening and confirm the door’s swing direction if you are considering a prehung model.
Final Recommendation
For a built-in pet opening in a screen-door format, the AINLARRY 30-inch pine model is the most straightforward choice if its measurements suit your doorway and your pet fits the stated limits. If you need a wider screen door, treat the AINLARRY 32-inch model’s conflicting weight details as a reason to confirm specifications before purchase. For a solid exterior replacement, consider the National Door Company unit after checking handing and pet-opening size. If you want to modify a door you already own, choose between the larger MIAOTONG and the medium Baboni based on the flap dimensions and your pet’s size.
