Best Automatic Dog Doors (2026 Guide)

An automatic dog door lets your dog go out to the yard and come back in on its own, while keeping strays, raccoons and the neighbor’s cat outside. It recognizes a tag or collar your dog wears and opens only for them. For most homes, the best automatic dog door is the Power Pet WiFi Smart Automatic Dog Door: it opens itself with a motor, locks with a deadbolt and works with an app, for about $580.

Not every dog door that calls itself smart opens on its own, so the options below cover both types: fully automatic doors with a motorized panel, and electronic doors with a locking flap your dog pushes through. They also cover small dogs, sliding glass doors and a budget option.

Quick Recommendations

• Power Pet WiFi Smart Automatic Dog Door — Best overall. A motorized, airtight door for dogs up to 100 lb, with schedules and alerts in an app.
• PetSafe SmartDoor Connected — Best for small dogs. An app-controlled flap that reads a collar key or your dog’s microchip.
• PetSafe Electronic SmartDoor — Best budget. A locking flap for dogs up to 100 lb that runs on batteries without Wi-Fi.
• Power Pet Roll Up — Best for tight spaces. The panel rolls into the frame, so the door fits under a window.
• Power Pet WiFi Patio Door — Best for sliding glass doors. Fits in the door track, so you don’t cut anything.

None of these doors list support for Apple Home, Google Home, Alexa or Matter, so you control each one in its own app or on the door itself. Every smart dog door here with Wi-Fi needs a 2.4 GHz network, which matters if your router only shows a combined 2.4 and 5 GHz network name.

Automatic or Electronic: How These Dog Doors Work

The words get mixed up a lot in product listings, but there are two different designs.

Fully automatic doors have a motor. When your dog walks toward the door, a sensor detects the collar, and a hard panel slides or rolls up out of the way, then closes behind them. Your dog never has to push anything, which helps older, smaller or nervous dogs. These doors seal tightly and lock with a deadbolt, but they’re bigger, more expensive and usually need an outlet. All three Power Pet options here work this way.

Electronic dog doors keep a normal swinging flap and add a lock. The flap stays locked until a dog with the right key comes close, then it unlocks so your dog can push through, and it locks again afterward. They cost less and run on batteries. The two PetSafe options work this way.

How the door recognizes your dog:

• Ultrasonic collar. Power Pet doors come with an MS-5 collar that works out of the box, with no pairing. Its battery needs replacing every two to three months, according to High Tech Pet.
• Collar key. The PetSafe doors use a small tag that clips onto your dog’s existing collar.
• Microchip. The Medium PetSafe SmartDoor Connected can also read the microchip your vet implanted, so a small dog doesn’t need to wear anything.

A Wi-Fi model adds remote control, schedules and alerts on your phone. If you also want to see your dog while you’re out, a pet camera pointed at the door shows you who comes and goes.

The Best Automatic Dog Doors in 2026

Power Pet WiFi Smart Automatic Dog Door — Best Overall

The Power Pet WiFi is the best choice for most dogs: it opens on its own in about a second, closes airtight with a deadbolt and lets you control it from your phone.

Best for: Medium and large dogs up to 100 lb, and owners who want a door that’s secure and doesn’t let drafts in.

What stands out in real use

When your dog walks toward the door wearing the included MS-5 collar, the motor raises a polycarbonate panel in about one second, according to High Tech Pet. The sensors are directional, so the door opens only when your dog approaches it directly, not when they walk past or sleep nearby. The panel closes by gravity and retracts if it meets an obstruction, and an automatic deadbolt locks it when it’s down. You can set the inside and outside sensors separately, which gives you four access modes: enter only, exit only, full access, or locked. The app adds remote open and close, a hold-open setting, schedules for when your dog can go in and out, an activity history and status notifications. Power Pet also sells a standard version without Wi-Fi for about $105 less.

Key specs

• Pet opening 12 1/4 x 16 inches, for dogs up to 100 lb
• Motorized panel with automatic deadbolt
• MS-5 ultrasonic collar included
• Wi-Fi, 2.4 GHz only
• AC adapter, rechargeable backup battery sold separately

Pros

• Opens and closes on its own
• Airtight seal keeps out drafts and rain
• Four access modes, set on the door or in the app
• Safety retract if the panel meets your dog

Cons

• The most expensive door-mount option here
• Collar batteries need replacing every two to three months
• Backup battery costs extra
• Wi-Fi works on 2.4 GHz only

Installation and compatibility notes

The door mounts on the surface of your door, so you only cut a hole the size of the panel, not the whole frame. A wall tunnel for wall installs is sold separately. Plug in the AC adapter near the door, and add the backup battery if your power goes out often, because without it the door stays closed during an outage. Each extra dog needs its own MS-5 collar, which costs about $60.

Price: ~$580

PetSafe SmartDoor Connected — Best for Small Dogs

The SmartDoor Connected is the PetSafe smart door to choose for a small dog: it unlocks for a collar key or your dog’s microchip, and the app lets you set a schedule for each pet.

Best for: Dogs up to 25 lb and homes with a cat and a small dog, where you want to control who goes out and when.

What stands out in real use

This Medium door unlocks its flap for the Pet Door Key on your dog’s collar, and it can also pair with your dog’s microchip, so a small dog can use it without wearing a tag. In the My PetSafe app, you set a separate schedule for each pet, choose whether they can go in, out or both, and lock the door remotely during a storm. The app also sends a notification when your pet uses the door, and alerts you about the lock status and low batteries. The flap is tinted, and a multi-point lock holds it shut. PetSafe says most pets learn to use the door on their own in four to six weeks.

Key specs

• Flap opening 7.1 x 7.8 inches, for pets up to 25 lb
• Pet Door Key included, microchip pairing
• Wi-Fi, 2.4 GHz only
• 4 C batteries, wall adapter sold separately
• Fits a door; a wall needs a tunnel extension

Pros

• Reads microchips, so your dog doesn’t need a tag
• Separate schedules for each pet
• Remote lock and phone notifications
• Runs on batteries, so it’s easy to place

Cons

• Medium size only fits small dogs
• Your dog has to push the flap
• Wall adapter costs extra
• Wi-Fi works on 2.4 GHz only

Installation and compatibility notes

Measure your dog’s chest height and width before you buy, and pick the size that fits their height if the numbers fall between two sizes. PetSafe also makes a Large SmartDoor Connected for dogs up to 100 lb. If you only need a door for your cat, see our guide to the best automatic cat doors. Use alkaline C batteries and replace all four together when the app warns you. If setup fails, make sure your phone and the door connect to a 2.4 GHz network.

Price: ~$270

PetSafe Electronic SmartDoor — Best Budget

The Electronic SmartDoor is the lowest-cost way to keep strays out with a large flap: it’s a locking electronic dog door that runs on batteries without Wi-Fi or an app.

Best for: Large dogs up to 100 lb, and owners who want a simple door they set once.

What stands out in real use

The flap stays locked until a dog wearing a SmartKey tag comes within range, then unlocks so your dog can push through, and locks again after they pass. You can adjust the range up to 3 feet and program up to five SmartKeys, and this listing comes with two. Settings on the door let you choose automatic mode, always unlocked or always locked, and PetSafe lists selective entry and exit. The door runs on four D batteries, so you don’t need an outlet nearby, and a light blinks red when the batteries are low. There’s no app, so you won’t get alerts or remote control.

Key specs

• Flap opening 11 x 16 inches, for pets up to 100 lb
• Two SmartKeys included, up to five supported
• Key range adjustable up to 3 feet
• 4 D alkaline batteries, not included
• No Wi-Fi

Pros

• Costs much less than a motorized door
• Large flap for big dogs
• Runs on batteries anywhere
• Works without Wi-Fi or an app

Cons

• Your dog has to push the flap
• Can’t lock it or check it from your phone
• A flap seals less tightly than a motorized panel
• Each SmartKey uses its own battery

Installation and compatibility notes

The door installs in an interior or exterior door, and PetSafe sells a wall kit separately. Use alkaline D batteries, not rechargeable ones. Test the key range while your dog sits next to the door: if the flap unlocks while they’re only resting nearby, shorten the range so it doesn’t stay unlocked.

Price: ~$188 (set with two SmartKeys)

Power Pet Roll Up — Best for Tight Spaces

The Roll Up is Power Pet’s newest automatic door: its panel rolls up into the frame instead of sliding up above the opening, so the whole door is much shorter.

Best for: Doors with a low window, walls under a windowsill, and very large dogs (an XL size fits dogs up to 200 lb).

What stands out in real use

The panel is made of interlocking polycarbonate segments that stay rigid when closed and roll into a compartment when the motor opens the door. That keeps the Large frame at 28 1/4 inches tall, according to High Tech Pet. It opens in about one second, runs under 40 dB and retracts if it meets an obstruction. Like the classic Power Pet, it works with the MS-5 collar and directional sensors, and you can set entry and exit ranges separately. The app adds daily entry and exit schedules, an activity history and real-time notifications. It also comes with a lock-out panel for when you’re away.

Key specs

• Large flap 19 inches high x 10 inches wide, for dogs up to 100 lb
• Also available in Medium (30 lb) and Extra Large (200 lb)
• MS-5 ultrasonic collar included
• Wi-Fi, 2.4 GHz only
• AC adapter, rechargeable backup battery sold separately

Pros

• Fits where a standard automatic door won’t
• Very quiet operation
• App schedules and notifications
• XL size for giant breeds

Cons

• The most expensive door-mount option here
• Narrower opening than the classic Large
• New design with fewer owner reviews
• Collar batteries need replacing every two to three months

Installation and compatibility notes

This listing is the door-mount version; a wall-mount version comes with an aluminum tunnel. Check that your dog fits the 10-inch width, since this panel is taller and narrower than the classic Power Pet’s 12 1/4-inch opening. The optional rechargeable battery keeps the door working during a power outage.

Price: ~$700

Power Pet WiFi Patio Door — Best for Sliding Glass Doors

The Power Pet patio door puts a full automatic dog door into a sliding glass door without cutting anything: the panel stands in the door track next to your sliding door.

Best for: Homes where the yard is behind a sliding door, and renters who can’t cut a door or a wall.

What stands out in real use

The patio panel has a heavy aluminum frame and dual-pane, Low-E glass, so it matches a sliding door, with the same motorized Power Pet door built in at the bottom. You get the same collar activation, directional sensors, safety retract and four access modes as the door-mount model, plus app control, schedules and a door history. This version fits sliding doors from 75 to 80 1/4 inches tall, and a Tall version covers taller doors. Since the panel sits in the track, you can take it out when you move.

Key specs

• Fits sliding door tracks 75 to 80 1/4 inches tall
• For dogs from 30 to 100 lb
• Aluminum frame, dual-pane Low-E glass
• MS-5 ultrasonic collar included
• Wi-Fi, 2.4 GHz only

Pros

• No cutting or permanent changes
• Moves with you
• Motorized, airtight panel
• App schedules and history

Cons

• The most expensive option here
• Your sliding door opens less wide
• Needs an outlet near the door
• Collar batteries need replacing every two to three months

Installation and compatibility notes

Measure the height of your sliding door track before you order, because the Regular and Tall versions cover different ranges. The panel fits next to the sliding part of the door, so check which side slides. Plan for a nearby outlet or an extension cord that your dog can’t reach.

Price: ~$915

How to Choose an Automatic Dog Door

Measure your dog first. PetSafe’s sizing guide says to measure chest height (from the back above the shoulder to the lowest point of the ribcage) and chest width, then compare them to the flap size. If you have more than one dog, measure the largest one. A puppy will grow, so buy for their adult size.

Choose where it goes. A door mount is the most common, a wall mount needs a tunnel, and a patio panel needs a sliding glass door. Renters usually can’t cut a door, which makes the patio panel the only option here that doesn’t need permanent changes.

Plan for power outages. The PetSafe doors run on batteries. The Power Pet doors run on an outlet, and without the optional backup battery they stay closed when the power goes out, so your dog can’t get in or out until it’s back.

Count the running costs. A Power Pet collar battery lasts two to three months, according to High Tech Pet, and an extra collar costs about $60. PetSafe’s doors use C or D batteries, and the SmartKey tags have their own batteries.

Think about security and wildlife. Every door here opens only for your own dog, but a large opening is still a way into your home. The Power Pet doors lock with a deadbolt, and all of them have a locked mode for nights and trips. If you want to see what’s going on outside the door, an outdoor security camera covers the yard.

Give your dog time to learn. Leave the door unlocked or open for the first few days, and reward your dog for going through. PetSafe says most pets use the SmartDoor Connected on their own after four to six weeks. If you’re away for long days, an automatic dog feeder can serve meals while your dog comes and goes.

The PetSafe Electronic SmartDoor is the budget option for large dogs, and it runs on batteries without Wi-Fi.
