A smart dog door lets your dog come and go on their own — but only your dog. Instead of a flap any raccoon or neighbor’s cat can push through, a smart door unlocks with your dog’s microchip, a collar tag, or an app, keeping strays and wildlife out. The right one depends on your dog’s size, your climate, and whether you want app control. Here are the best smart dog doors of 2026 and how to pick.
What to look for in a smart dog door
- How it unlocks. Microchip doors read the chip your dog already has (no extra collar gadget). Others use an RFID collar tag or an ultrasonic collar. App-connected doors add remote lock/unlock and entry logs.
- Size fit. Doors are rated by pet weight and flap size — a door built for a cat won’t fit a Labrador, and vice versa. Match it to your dog.
- Weatherproofing. If you get wind, cold, or rain, a well-sealed, insulated flap matters for drafts and energy bills.
- Power. Most run on batteries (often ~12 months); some large-dog motorized doors use AC power with battery backup.

Our top picks
SureFlap Microchip Pet Door Connect — best microchip door
The SureFlap is the go-to microchip door because it uses the chip your dog already has — no extra collar tag to lose. It reads 9, 10, and 15-digit ISO microchips, so it works with virtually any chipped pet, and the optional Connect Hub adds app control and entry logs. It’s rated for cats and small dogs up to about 15 pounds and runs roughly a year on C-cell batteries. For multi-pet homes that need to keep strays out, it’s the best pick.
PetSafe SmartDoor — best for medium and large dogs with app control
If your dog is bigger, the PetSafe SmartDoor scales up to about 40 pounds and unlocks with an RFID collar tag. Its standout feature is direct Wi-Fi, letting you lock or unlock the door remotely from anywhere and get entry notifications — no separate hub required. At around $217 it’s the best blend of size range and smart control for most dog owners.
High Tech Pet Power Pet — best for large dogs and security
For big breeds and maximum security, the Power Pet uses an ultrasonic collar to trigger a motorized panel that slides open and seals shut with a steel deadbolt, so the flap can’t be pushed in from outside. It fits large dogs from 30 to 100 pounds, runs on AC power (or D-cell backup), and carries the top weatherproofing rating. It’s the priciest option at around $475, but nothing beats it for a large dog and a secure home.
Endura Flap Smart Pet Door — best weatherproofing
If you live somewhere cold, windy, or coastal, the Endura Flap is built for it: a dual-insulated flap system rated to withstand strong wind, available in multiple sizes, and paired with separate microchip readers for selective entry. It’s the choice when keeping drafts and energy loss out matters as much as keeping strays out.
A few things to know before you install
Smart dog doors take some setup. Your dog needs to be comfortable pushing through a flap — train it gradually with treats and the door propped open at first. Check that your wall or door thickness suits the model, and confirm your dog’s microchip type (for microchip doors) before buying. Battery-powered doors will need fresh batteries roughly once a year, so pick a model with a low-battery alert if you can.
Common Questions
Do smart dog doors use my dog’s existing microchip?
Microchip doors like the SureFlap and Endura read the ISO chip your dog already has. Others (PetSafe, Power Pet) use a collar tag or collar device instead.
Will a smart door keep other animals out?
Yes — that’s the point. The door only unlocks for your dog’s registered chip or collar, so strays, raccoons, and the neighbor’s cat can’t get in.
What size dog door do I need?
Match the door’s weight rating and flap dimensions to your dog. Cat/small-dog doors top out around 15 pounds, while large-dog doors like the Power Pet handle up to 100 pounds.
Do smart dog doors work in a power outage?
Battery-powered doors keep working normally. Motorized AC doors like the Power Pet include battery backup so they still operate during an outage.
The Bottom Line
For most homes the SureFlap Microchip Connect (small dogs) or the PetSafe SmartDoor (medium and large dogs, with app control) are the best smart dog doors of 2026. Big-breed owners who want maximum security should look at the High Tech Pet Power Pet, and anyone in a harsh climate at the Endura Flap. Give your dog a little training to use the flap, and you’ll both enjoy the freedom. Pair it with a GPS tracker for peace of mind once your dog can come and go.
