A built-in pet flap saves you from cutting a hole in a new door, but the right choice depends on more than the opening for your dog or cat. Check whether you’re buying a complete prehung door or just a slab, measure your existing frame, and compare the pet flap dimensions with your pet. These five options include glazed exterior door slabs and a pine screen door, so they suit different entryways and needs.

Our Picks: Best Exterior Door With Built In Pet Door reviews
Best for a Wider Entry: SOLRIG 36-Inch 9-Lite Door Slab
This SOLRIG slab pairs a nine-lite clear glass design with a built-in pet flap. The double-tempered, double-glazed glass brings natural light into an entryway, while the flap measures 16¼ by 11 inches and is listed for pets up to 100 pounds. A magnetic seal and three-position control add ways to manage the opening.
The slab is 36 inches wide, 80 inches tall, and 1.73 inches thick. Its solid wood and MDF construction has a waterproof, UV-resistant primer, so you can paint it to suit your exterior. The listing says hinges, jamb, and lock hardware are not included. That makes it a better fit for a replacement project where you already have compatible hardware or plan to source it separately.
Compared with the 32-inch SOLRIG option, this model gives you the same listed pet-flap dimensions in a wider slab. It’s worth considering if your doorway is sized for a 36-inch door, but the slab-only format means it is not a full, ready-to-hang door package.
Pros:
- Large 16¼-by-11-inch pet flap, listed for pets up to 100 pounds
- Nine-lite double-tempered glass brings daylight into the entry
- Primed surface can be painted to match your home
- Magnetic seal and three-position control help manage the flap
Cons:
- Hinges, jamb, and lock hardware are not included
- Requires an opening sized for a 36-inch slab
Verdict: Choose this slab if you need a 36-inch glazed door with a large built-in pet flap and are prepared to supply the frame hardware.
Best for a Narrower Entry: SOLRIG 32-Inch 9-Lite Door Slab
This 32-inch SOLRIG slab has the same core features as the wider model: nine clear glass panes, double-tempered glazing, a primed wood-and-MDF build, and a built-in pet flap. The opening measures 16¼ by 11 inches and is listed for pets up to 100 pounds. The flap also has a magnetic seal and three-position control.
At 32 by 80 inches and 1.73 inches thick, it may suit an entry that cannot take the wider slab. The finish is primed for painting, but this is still a slab-only product. Hinges, jamb, and lock hardware are not included, so check what your current frame can reuse before ordering.
Its main trade-off against the 36-inch version is width, not pet-flap size. If your opening is built for a 32-inch door, this model keeps the larger listed flap without requiring the wider slab. Measure carefully: the product information recommends a rough opening two inches wider and taller than the slab, but a professional installer can confirm what your specific frame needs.
Pros:
- 32-inch width for openings that cannot accommodate a 36-inch slab
- Large pet flap with a magnetic seal and three-position control
- Double-tempered, double-glazed glass
- Paint-ready primer allows you to choose the finish
Cons:
- Does not include hinges, jamb, or lock hardware
- Requires careful measurement and installation planning
Verdict: This is a sensible option when you want the SOLRIG glass-and-pet-flap combination in a 32-inch slab and already have a plan for the frame and hardware.
Best for a Screen-Door Setup: AINLARRY Pine Screen Door
Unlike the glazed entry slabs, this AINLARRY model is a pine screen door with a mesh panel and built-in pet access. The mesh is intended to allow airflow while keeping bugs out, making the door more suitable for a porch, patio, or use alongside a storm door than as a sealed primary exterior door.
The panel measures 32 by 80 inches and is 1.38 inches thick. Its pine frame is sanded and primed, so you can use or customize the finish. The listing gives fit guidance for openings with and without a jamb; check those measurements against your own doorway rather than relying on the nominal door size alone.
There is an important specification mismatch to resolve before buying: the description says the pet opening suits dogs under 120 pounds and under 25 inches at the shoulder, while the product details list a maximum weight capacity of 27 pounds. Confirm the intended pet limit with the seller before relying on either figure. Some users also report that the frame can shift or feel less rigid when hung, so added reinforcement may be needed depending on your installation.
Pros:
- Pine frame and mesh panel provide a screen-door option with airflow
- Built-in pet access avoids cutting a separate opening
- Primed surface can be painted or stained
- Published fit guidance covers openings with and without a jamb
Cons:
- Conflicting pet-weight specifications should be confirmed before purchase
- Screen construction is not a substitute for a solid, sealed exterior entry door
Verdict: Consider this door for a porch or screen-door application, but verify pet compatibility and plan for a secure, well-supported installation.
Best Alternative 36-Inch Slab: LAKEYON 9-Lite Door with Pet Flap
LAKEYON’s 36-by-80-inch door combines a nine-lite glass layout with a built-in pet flap. The flap opening is 15.16 inches high by 10.75 inches wide, and the listing says it supports pets up to 100 pounds. That opening is slightly smaller than the 16¼-by-11-inch flap on the SOLRIG slabs, so compare the actual opening with your pet’s height and width before choosing.
The door uses double-tempered glass and a CARB P2-certified MDF construction with a solid wood core. Its waterproof, UV-resistant primer is paint-ready. The listing describes a safety closing panel and magnetic seal to help keep the flap closed and limit dust and insects.
This is another slab-only choice, and its listing says hinges are not included. The stated rough opening is two inches wider and 2½ inches taller than the slab, so take that guidance into account when checking your frame. Compared with the SOLRIG 36-inch model, LAKEYON has a somewhat smaller pet opening and a different listed rough-opening requirement.
Pros:
- Nine-lite design with double-tempered glass
- Built-in flap with a safety closing panel and magnetic seal
- Paint-ready primer and stated water- and UV-resistant coating
- Listed for pets up to 100 pounds
Cons:
- Pet flap is smaller than the openings listed for the SOLRIG slabs
- Hinges are not included
Verdict: Pick this 36-inch slab if its slightly smaller flap suits your pet and you prefer its specified construction and finish details.
Best Door-and-Jamb Package: SOLRIG 32-Inch Slab with Prehung Jamb
This SOLRIG option stands out because the package includes a 32-by-80-inch door slab and a prehung exterior jamb, with hinges installed on the frame. The listing says the two parts are sent in separate packages, so plan for a two-package delivery. The product is described as right-handed, making it especially important to check the handing against your doorway before ordering.
The slab has nine clear glass panes, double-tempered glazing, and a solid wood and MDF build with waterproof, UV-resistant primer. Its adjustable magnetic pet flap measures 16¼ by 11 inches and is listed for cats and dogs up to 100 pounds. The frame’s weatherstripping and seals are intended to reduce drafts, air leakage, and outdoor noise.
Although the listing includes a jamb and installed hinges, it says the slab has no pre-drilled holes, allowing customized handle and hinge positions. Confirm exactly how the supplied jamb and slab are configured, along with the required handle hardware and opening dimensions, before purchase. Compared with the slab-only options, this package may reduce the need to source a jamb separately, but it calls for more careful checks of handing and fit.
Pros:
- Includes a jamb with hinges already installed on the frame
- Large adjustable pet flap with magnetic seals
- Weatherstripping is intended to help limit drafts and noise
- Primed surface can be painted to match your exterior
Cons:
- Jamb and slab are shipped in separate packages
- Right-hand configuration and hardware details need careful checking
Verdict: This is the strongest fit if you want a 32-inch door package with a jamb and installed hinges, provided the handing and opening match your home.
How to Choose an Exterior Door with a Built-In Pet Door
Decide Whether You Need a Slab, a Door Package, or a Screen Door
A door slab is only the moving panel. It may not include a jamb, hinges, or lock hardware, so you’ll need to use compatible existing parts or buy them separately. A door-and-jamb package can simplify sourcing, but confirm what is included and whether the door’s handing matches your entry. A mesh screen door serves a different purpose: it allows airflow and is not the same as a solid, sealed primary exterior door.
Measure the Door and the Opening
Measure the existing door slab, its thickness, and the rough opening. Do not assume the nominal size alone guarantees a fit. The SOLRIG slab listings recommend a rough opening two inches wider and taller than the slab; LAKEYON gives a different height allowance. Follow the measurements for the exact product you choose, and ask an installer to check the frame if its dimensions or condition are uncertain.
Check the Pet-Flap Opening Against Your Pet
Compare the flap’s clear opening—not just the door size—with your pet’s height and width. The SOLRIG models list a 16¼-by-11-inch flap, while LAKEYON lists a 15.16-by-10.75-inch opening. A stated weight limit is not a substitute for checking whether your pet can pass through comfortably. The AINLARRY listing gives conflicting weight information, so verify its limit with the seller before buying.
Consider Weather Sealing and the Door’s Location
A pet flap creates an opening through the door, so consider how much weather protection you need and whether the listing describes a magnetic seal or closing panel. The SOLRIG door-and-jamb package also describes weatherstripping around the frame. The AINLARRY mesh screen door is designed for airflow and bug screening, not the same level of separation as a solid exterior door.
Match the Material and Finish to Your Entryway
The SOLRIG and LAKEYON options use solid wood and MDF construction with a primed surface. Their primer is described as paint-ready, which gives you room to customize the color. AINLARRY uses a pine frame and mesh panel with a sanded, primed surface. Consider the product’s intended role and the finish you want before deciding which construction suits your entry.
Check Handing, Hardware, and Installation Needs
Confirm whether hinges, a jamb, and lock hardware are included. The SOLRIG slab-only doors exclude those parts, while the 32-inch SOLRIG package includes a jamb with hinges installed on the frame. That package is identified as right-handed. Professional installation is recommended for the SOLRIG slabs, and a careful fit check is useful for any exterior door with a pet opening.
Frequently Asked Questions
Are these products complete, ready-to-install doors?
Not all of them. The 32- and 36-inch SOLRIG listings and the LAKEYON listing describe slab-only products, with some hardware excluded. The 32-inch SOLRIG package includes a jamb and hinges installed on the frame. Check the exact listing for all included parts before ordering.
Do these doors fit every standard doorway?
No. Door size, rough opening, jamb dimensions, slab thickness, and handing all affect fit. Measure your existing opening and compare it with the product-specific fit instructions. If you’re replacing a door in an older or modified frame, ask an installer to verify the measurements.
How do I know whether the pet flap is large enough?
Measure your pet’s height and width and compare those measurements with the flap opening. The listings provide different flap dimensions, so do not choose based only on the door’s overall width or a stated pet weight limit.
Can I paint these doors?
The SOLRIG and LAKEYON slabs have a primed surface described as paint-ready. The AINLARRY screen door is described as sanded and primed for customization. Follow the product instructions and choose a finish suited to the door’s material and location.
Is the AINLARRY screen door suitable as my main exterior door?
It is described as a wooden screen door with a mesh panel for airflow and bug screening. It does not have the same solid, sealed construction as the glazed entry door slabs, so it is better suited to a porch or screen-door setup than to replacing a primary exterior door on its own.
Do the built-in pet flaps keep out drafts and insects?
The SOLRIG and LAKEYON listings describe magnetic seals or closing panels intended to help limit drafts, dust, or insects. These features do not guarantee a fully airtight seal. The AINLARRY screen door has mesh intended to help keep bugs out while allowing airflow.
Final Recommendation
For a solid glazed entry door with a large pet flap, the SOLRIG slab is a strong place to start: choose the 32- or 36-inch width that matches your opening, and remember that the slab-only listings do not include the jamb or hardware. If you want a jamb with hinges included, consider the 32-inch SOLRIG package after confirming the right-hand configuration and fit. Choose the AINLARRY model for a screen-door role, and verify its conflicting pet-weight details before ordering.
