Best indoor dog gates compared
Carlson Extra Wide Pet Gate
Carlson earns the overall pick because its small pet door solves a real problem in a mixed-size household: a cat can reach a separate room without requiring a person to open the full gate each time. The metal frame stands 30 inches high and fits openings of 29 to 32 inches on its own, or 34 to 36.5 inches with the included four-inch extension. Adults use a 16.5-inch walk-through opening with a one-touch latch. The pressure-mounted design uses wall cups and hardware, so follow the installation instructions rather than relying on pressure alone. Its limitation is the unsupported 32 to 34-inch interval; the little door can also defeat the barrier if the dog can squeeze through it. Measure both the opening and your animals before choosing it.
Pros
- Small pet door permits a cat to pass without opening the main gate
- 16.5-inch walk-through opening has a one-touch latch
- Four-inch extension covers supported openings up to 36.5 inches
Cons
- Does not fit openings from 32 to 34 inches
- A small dog may fit through the pet door when it is open
Regalo Easy Step Gate
The Easy Step earns its wide-doorway badge because its included six-inch extension reaches supported openings up to 38.5 inches, two inches wider than the Carlson. The white metal gate is 30 inches high and has a walk-through door and locking system, making it a straightforward choice for a hallway used frequently by people and a small or medium dog. It fits 29 to 32 inches without the extension and 35.5 to 38.5 inches with it. That is not a continuous range: an opening between 32 and 35.5 inches is unsuitable for this set. Wall cups are required for installation, and the manufacturer says never to use this pressure-mounted model at the top of stairs. Unlike Carlson, it offers no separate cat passage.
Pros
- Six-inch extension reaches a supported 38.5-inch opening
- Walk-through door avoids lifting out the whole gate for every passage
- Metal frame provides a solid indoor boundary for suitable pets
Cons
- The included configuration does not fit the 32 to 35.5-inch gap
- No small pet door lets a cat pass independently
Toddleroo Supergate Ergo
The Toddleroo Supergate Ergo takes the flexible-mounting badge because its plastic panel can be pressure mounted for a removable barrier or hardware mounted to swing open. It adjusts from 26 to 42 inches wide, which covers some narrow and wide openings outside the other two gates' stated ranges, and stands 26 inches tall. An easy-press handle controls the panel, and the listed mounting hardware is included. Choose it if a temporary room division and a wider adjustment span matter more than the extra height of a metal walk-through gate. For stairs, the manufacturer requires hardware mounting; do not assume the pressure setup is equivalent. Its lower height is a meaningful drawback for a dog that jumps, and the solid panel must be moved or swung open for people to pass.
Pros
- Adjusts from 26 to 42 inches without the metal gates' extension gap
- Offers pressure mounting or a hardware-mounted swinging setup
- Ergonomic handle releases and locks the adjustable panel
Cons
- At 26 inches tall it offers less height against a jumping dog
- Pressure mounting is not the manufacturer-approved stair configuration
Choosing and installing a gate
Measure the clear distance between the exact surfaces that will hold the gate, including skirting or trim. Check the full fit chart, not merely the largest number: an extension can leave a gap between supported settings. If the wall is uneven or the mounting point is weak, consult the instructions before installing. A door that opens comfortably for an adult also needs room to swing without striking furniture.
Match the barrier to the particular dog. A tall or athletic animal may jump a 30-inch gate, and a puppy can slip between bars or through a pet door intended for a cat. Supervise the introduction and check the latch, wall cups and contact points regularly. A gate manages access to a room; it is not a substitute for training, supervision or a secure exterior enclosure.
FAQ
Can a cat pass through a dog gate?
The Carlson has a dedicated small pet door for a cat or other suitably sized animal. Check that the cat can move comfortably through it and that the dog you want to contain cannot follow. If both animals are similarly small, a separate pet door may not provide useful separation and should remain closed when containment matters.
Is a pressure-mounted gate suitable at the top of stairs?
Do not use the Regalo Easy Step at the top of stairs: its listing expressly warns against it. Toddleroo specifies hardware mounting for stairway use. Follow the exact model's installation instructions, use the included fittings as directed and confirm that the mounting surfaces are sound; a gate's headline width alone does not establish suitability for a stair landing.
What if my doorway is between the listed ranges?
Do not stretch or improvise a fit. Carlson lists no fit for 32 to 34 inches, while Regalo excludes 32 to 35.5 inches with the included configuration. Measure again at the actual mounting height, including trim, then choose a gate whose stated range covers that measurement or an extension explicitly approved for the model.
