A solid exterior door with a built-in dog door can save you from cutting a flap into a new door yourself, but the right choice depends on your opening size, your dog’s fit, and whether you need a door slab or a complete prehung setup. The options below pair pet access with glass panels, so consider how much daylight and visibility you want at your entryway. The supplied listing data marks all three products as unavailable; check each linked listing before making plans to buy.

Best for a Wide Entry: SOLRIG 36 x 80-Inch 9-Lite Door Slab
This SOLRIG is a 36 x 80-inch exterior door slab with a 9-lite clear glass design and a built-in dog door. Its pet flap measures 16-1/4 x 11 inches and is listed for pets up to 100 pounds. A three-position setting and magnetic seal are intended to help control the flap and close it after your pet passes through.
The door combines a solid wood core with white MDF and a waterproof, UV-resistant primer. The primed surface can be painted, which gives you room to match your trim or exterior color. Double tempered glass is specified for the window panels. Because the glass is clear, it brings light into the entry but also allows visibility through the door.
This is a slab-only option, not a complete door unit. Hinges, jamb, and lock hardware are not included, and the slab has a stated thickness of 1.73 inches. The listing recommends a rough opening 2 inches wider and 2 inches taller than the slab, but you should still check your existing frame and get professional installation help if needed.
Compared with the 30-inch SOLRIG, this model offers a wider slab and the same listed pet-flap size, but it does not include a prehung jamb. It may suit you if you already have a compatible frame and want a large dog opening. The main tradeoffs are the extra installation work and the need to source compatible hardware.
Pros:
- Large 16-1/4 x 11-inch pet flap, listed for pets up to 100 pounds
- 9-lite clear glass and double tempered glazing
- Paint-ready primed surface
- Magnetic flap seal with three-position control
Cons:
- Slab only; hinges, jamb, and lock hardware are not included
- Clear glass may not suit entries where privacy is a priority
Verdict: Choose this SOLRIG if you need a 36-inch slab with a large built-in pet flap and already have a suitable frame or plan to arrange a full installation.
Best with a Prehung Jamb: SOLRIG 30 x 80-Inch 9-Lite Exterior Door
This 30 x 80-inch SOLRIG is the narrower option in this group. It has a 9-lite clear glass panel, a built-in adjustable magnetic dog door, and a prehung exterior jamb. The listed pet flap measures 16-1/4 x 11 inches and is intended for cats and dogs up to 100 pounds.
The flap uses magnetic seals at the sides and bottom, plus an adjustable rear panel. The listing describes the door frame as sealed with noise-reducing weatherstripping, which is intended to limit drafts and outdoor noise. Double tempered insulated glass and a solid wood core with white MDF round out the stated construction details.
The package includes the door and a prehung jamb, with hinges already installed on the frame. The listing says the parts are sent in two packages. It also notes that the slab has no pre-drilled holes, allowing handle placement to be chosen during installation. Confirm the handing and measurements carefully: this model is described as right-handed and is only 30 inches wide.
Of these three choices, this one includes the most framing components, but it is not a full hardware package: the listing does not state that a lock or handle is included. It may reduce some assembly work compared with a slab-only door, but you still need to verify that the jamb and handing match your opening. The listing does not provide a recommended rough-opening size, so ask the seller or installer to confirm the fit before ordering.
Pros:
- Prehung jamb with hinges already installed on the frame
- Adjustable magnetic flap with side and bottom seals
- Large 16-1/4 x 11-inch pet opening, listed for pets up to 100 pounds
- Weatherstripping and double tempered insulated glass are specified
Cons:
- 30-inch width may not fit openings designed for a 36-inch door
- Confirm handle, lock, and rough-opening requirements before purchase
Verdict: This is the strongest fit if your opening calls for a 30-inch door and you want a prehung jamb included, provided you confirm the handing and installation details first.
Best for a Simple Glass Layout: Lakenyon 36 x 80-Inch 1-Lite Door Panel
The Lakenyon is a 36 x 80-inch exterior door panel with a single clear glass section and a built-in pet flap. The flap opening measures 15.16 x 10.75 inches, and the listing says it is designed for pets up to 100 pounds. Its opening is slightly smaller than the 16-1/4 x 11-inch flaps on the SOLRIG models, so compare the measurements with your dog before choosing.
The panel is described as CARB P2-certified MDF with a waterproof primer and UV coating. It also has SGCC-certified double tempered glass, which the listing describes as stronger and safer than regular glass. The primed door can be painted, while the one-lite design gives the entry a simpler look than the SOLRIG 9-lite options.
This listing is for the door panel only. It does not include hinges or handles, and it has no pre-drilled holes. The stated thickness is 1.73 inches. The recommended rough opening is 2 inches wider and 2.5 inches taller than the panel, so measure the frame and check those requirements before purchase.
Compared with the 36-inch SOLRIG, the Lakenyon has a smaller pet opening and a one-lite glass layout rather than nine smaller panes. It may suit you if you prefer that simpler window design and are comfortable sourcing the remaining hardware. Its slab-only format means installation planning remains important.
Pros:
- 36 x 80-inch panel with a paint-ready primed surface
- Double tempered glass with SGCC certification specified
- One-lite design for a simpler glass layout
- Pet flap listed for pets up to 100 pounds
Cons:
- Pet opening is smaller than the SOLRIG flaps
- Panel only, with no hinges or handles and no pre-drilled holes
Verdict: Consider the Lakenyon if you want a 36-inch slab with a one-lite glass design and its slightly smaller pet flap fits your dog.
How to Choose an Exterior Door with a Dog Door
Measure the door and rough opening
Start by measuring the existing door slab and the rough opening, not just the visible doorway. A slab-only door may need a different frame or installation work than a prehung unit. The two 36-inch listings provide rough-opening guidance, but their stated height allowances differ. The 30-inch SOLRIG listing does not give a recommended rough-opening size, so confirm it with the seller or an installer before ordering.
Check your dog’s fit through the flap
Compare the pet door’s opening dimensions with your dog’s height and width, and allow for comfortable movement. The SOLRIG flaps measure 16-1/4 x 11 inches; the Lakenyon flap measures 15.16 x 10.75 inches. Each is listed for pets up to 100 pounds, but weight alone does not tell you whether a particular opening will be comfortable for your pet.
Decide between a slab and a prehung door
A slab-only door can work when you have a compatible frame or want an installer to handle the fit. You will need to account for the missing jamb and hinges, and possibly handles or lock hardware. The 30-inch SOLRIG includes a prehung jamb with hinges installed on the frame, but you still need to confirm door handing and what hardware is included.
Consider the flap’s seals and controls
A dog flap is an opening in an exterior door, so check how it closes and whether you can limit access when needed. The SOLRIG models specify magnetic seals and adjustable controls; the 30-inch model also describes side and bottom seals. Look closely at the listed settings and flap design to decide whether they meet your needs for pet access and controlling drafts or unwanted entry.
Choose a glass layout that works for your entry
The SOLRIG doors use a 9-lite clear glass design, while the Lakenyon uses a 1-lite design. Both styles bring natural light into an entry, but clear glass also provides a view through the door. Think about privacy and the location of the doorway, and check whether the glass pattern fits the look you want.
Review the material and finish details
These products are described as combinations of MDF and solid wood core or as MDF panels; they should not be treated as solid-wood doors. Each listing describes a primed surface that can be painted. If your entry is exposed to harsh weather or frequent moisture, confirm the product’s installation requirements and finish-care guidance before choosing.
Plan for installation and hardware
Check what comes in the package, including hinges, jamb, handle, and lock components. The two 36-inch models are panels or slabs without hinges and handles, while the 30-inch SOLRIG includes a prehung jamb and installed hinges. The listings recommend professional installation, and careful measurement is especially important when a door has no pre-drilled hardware holes.
Frequently Asked Questions
Are these doors made entirely of solid wood?
No. The listings describe mixed construction. The SOLRIG doors use a solid wood core with MDF, while the Lakenyon is described as CARB P2-certified MDF. Check the full product specifications if you need a particular material.
Do these doors include a frame?
Only the 30 x 80-inch SOLRIG listing specifies a prehung exterior jamb with hinges installed on the frame. The 36-inch SOLRIG and Lakenyon listings are for the door slab or panel only.
Will a dog weighing up to 100 pounds fit through any of these flaps?
All three listings describe their pet doors as suitable for pets up to 100 pounds. However, the flap dimensions differ, and a weight limit does not guarantee a comfortable fit for every dog. Measure your pet and compare those measurements with the opening.
Are the glass panels clear or private?
The products are described as having clear glass. That can brighten the entryway, but it may not provide much privacy. Consider the door’s location and whether clear glass suits your needs.
Can I paint these doors?
The listings describe the doors as having a primed surface that can be painted. Follow the product’s installation and finish instructions, and confirm the right paint and preparation steps with the seller or installer.
Which option includes a prehung jamb?
The 30 x 80-inch SOLRIG is the only one of these three listings that specifies a prehung jamb. It is described as right-handed, so confirm that the handing matches your doorway before ordering.
Which door is the best overall choice?
The best fit depends on your opening and installation needs. The 36-inch SOLRIG offers the largest listed flap among the 36-inch choices, the 30-inch SOLRIG includes a prehung jamb, and the Lakenyon has a simpler one-lite glass layout. Verify availability, measurements, and included hardware before you choose.
Final Recommendation
For a 36-inch entry and a large pet opening, the SOLRIG 36 x 80-inch 9-lite slab is the most straightforward match, as long as you are prepared to source a jamb and hardware. If your opening is narrower and you want a prehung jamb, consider the 30-inch SOLRIG after confirming the handing and fit. Choose the Lakenyon for its one-lite layout if its smaller flap suits your dog. In every case, verify the listing status and measurements before purchase.
