Smart pet doors come in three kinds, and the outlets we read sort them by pet size. Motorized doors — High Tech Pet's Power Pet — lift a panel out of the way when a pet wearing an ultrasonic collar approaches head-on, then lock it with a deadbolt; Dogster ranks the PX-1 its best electronic dog door overall and Canine Journal makes the Wi-Fi version its winner [src1, src2]. Collar-key flaps — the PetSafe Electronic SmartDoor — unlock a conventional flap for a SmartKey on the collar and relock when the key moves away; Dogster calls it the best electronic dog door for the money, Canine Journal its best budget door and SmartHomePerfected its top pick for large dogs [src1, src2, src3]. Microchip flaps — SureFlap and Cat Mate — read the chip your vet already implanted, so the pet wears nothing; SureFlap designs its pet doors for large cats and small dogs, and Canine Journal names the SureFlap Connect its best door for small dogs, adding that it is not its winner because it will not suit a medium or large dog [src2, src5].

Wayzn sits apart: rather than going through the wall, it slides an existing two-panel sliding glass door open, and Canine Journal makes it its pick for sliding doors [src2, src14]. App control comes three ways on this card — the SureFlap Connect through its separate Hub, the Power Pet WiFi and the Wayzn over your Wi-Fi [src5, src13, src10]. Most of the dog-door roundups here (Dogster, Canine Journal, SmartHomePerfected) choose mainly from research, owner reviews and personal experience rather than structured tests; the hands-on reviews are Trusted Reviews' test of the SureFlap Connect, The Gadgeteer's of the Wayzn, Gagadget's, and the cat-flap tests at PetsRadar and Expert Reviews [src1, src2, src3, src4, src6, src8, src9, src10].

Best Overall: High Tech Pet Power Pet PX-1 (Medium) — Check price

Dogster's best overall electronic dog door "for the price point, level of security, and sensor capabilities". [src1] Instead of unlocking a flap, the panel rises out of the way when a pet wearing the ultrasonic collar approaches, so the dog never has to push through anything; Dogster adds that it opens only when the pet is approaching, and that the bulletproof-resin panel is airtight and locks with an automatic deadbolt. [src1] There are four modes — in only, out only, full access, closed and locked. [src1] The PX-1 accommodates pets up to 30 lb through an 8-1/4 x 10 in. opening, and runs on an AC adapter with an optional back-up battery. [src11] Canine Journal's winner is the same Power Pet door with Wi-Fi app control added — it is on this card as the Power Pet WiFi (Medium), below. [src2] The catch Dogster names: the door may break down after a year, and the company sends replacement parts rather than a new door. [src1] High Tech Pet's own store listed the PX-1 in stock when we checked on 2026-10-11. [src11]

Best Value: PetSafe Electronic SmartDoor (Large) — Check price

Dogster's best value and "the best electronic dog door for the money", Canine Journal's best budget door, Gagadget's editor's choice and SmartHomePerfected's top pick for large dogs. [src1, src2, src6, src3] A SmartKey on the collar unlocks the battery-powered flap as the pet nears, and the flap locks again once the key is out of range; it can be programmed for up to five keys. [src1, src2] The Large fits pets up to 100 lb. [src2] Canine Journal lists the same door as the PetSafe Never Rust Electronic Pet Door with a sensor collar key. [src2] What the outlets warn about: it needs four D batteries and its plastic flap may not hold up well (Dogster), the sensor is "a bit glitchy" and the flap can shut on a long-tailed cat (Catster), and closing takes several seconds (Gagadget). [src1, src7, src6]

Best for Cats and Small Dogs: SureFlap Microchip Pet Door Connect — Check price

Canine Journal's best door for small dogs and SmartHomePerfected's top pick for small dogs; Trusted Reviews tested it with three cats and gave it 4.5 out of 5. [src2, src3, src4] It opens for your pet's implanted microchip, or a SureFlap collar tag for a pet without one, so strays and neighbors' cats stay out; any animal can go out. [src5, src2] Trusted Reviews found the app's notifications arrived about 20 seconds after a pet used the door, liked being able to lock it remotely and set curfews, and found changing the four C batteries fiddly when the door is fitted next to a wall. [src4] The Amazon listing we link is the door WITHOUT the Hub: the app, notifications, remote locking and app curfews that the reviewers describe all need SureFlap's Hub, sold separately, which plugs into your router. [src5, src4] Canine Journal is plain about the limit: it is designed for cats and small dogs and will not work for a medium or large dog, which is why it is not that outlet's winner. [src2] The Amazon listing showed stock on 2026-10-11; Sure Petcare's US page sends buyers to retailers ("Where to buy"). [src5]

Best Automatic Door for Large Dogs: High Tech Pet Power Pet PX-2 (Large) — Check price

The PX-1's motorized door in the large size, for pets up to 100 lb. [src12, src1] Gagadget names it its best secure, premium choice, Catster its premium choice, and Dogster and SmartHomePerfected include it in their picks. [src6, src7, src1, src3] Its ultrasonic sensing is directional, so the panel opens when the dog walks straight at it rather than when it lies nearby, and it has the same four access modes and automatic deadbolt as the PX-1. [src12, src6] Dogster's warning applies here too: after a while it may malfunction and need costly repairs. [src1] High Tech Pet's store listed the PX-2 in stock when we checked on 2026-10-11. [src12]

Best App-Controlled Automatic Door: Power Pet WiFi (Medium) — Check price

Canine Journal's winner among smart dog doors: the motorized Power Pet door, opened by a waterproof ultrasonic collar, with a smartphone app that opens and closes the door, creates schedules and shows its activity history. [src2] High Tech Pet adds up to 20 custom timers and control from anywhere with an internet connection. [src13] The Medium is for pets up to 25 lb; Canine Journal notes it also comes in a large size, which is not linked on this card. [src13, src2] High Tech Pet's store listed it in stock when we checked on 2026-10-11. [src13]

Best Microchip Door Without an App: SureFlap Microchip Pet Door — Check price

Gagadget's best overall smart dog door, Expert Reviews' best microchip door for larger cats, and one of Dogster's five electronic dog doors. [src6, src9, src1] It is the SureFlap pet door without the app: microchip or collar-tag entry, a curfew mode that locks and unlocks at set times, 32 stored pets, and four C batteries that last up to 12 months. [src15, src6] Expert Reviews used it with a 7.5 kg cat. [src9] Dogster notes it can take two to three seconds to unlock, and Gagadget that a small animal may learn to open the outside flap from the other direction. [src1, src6] Our price checks have found no Amazon offer for it since 2026-09-11.

Best for Sliding Glass Doors: Wayzn Smart Pet Door — See at Wayzn

Canine Journal's pick for sliding doors: Wayzn turns a sliding glass door into an automatic door for pets, with no hole cut in the house. [src2, src10] The Gadgeteer's reviewer installed it on his own door with peel-and-stick adapters, opened it from the app and with Alexa 10 to 15 times a day, and found it reversed before pinching his hand or his dog's snout; its motion detection never worked reliably for him. [src10] It fits only two-panel sliding doors whose fixed panel is the outer one, and needs an outlet within reach of its 6.5 ft cord. [src14, src10] Wayzn's own store listed it in stock at $549 when we checked on 2026-10-11. [src14]

For Cats, With a Curfew Timer: Cat Mate Elite Microchip Cat Flap (355) — Check price

PetsRadar's best microchip cat flap with timer control, and Catster's pick for kittens. [src8, src7] Its LCD shows whether a cat is in or out, the lock status and when the flap was last used, and its timer sets a curfew without an app. [src8, src7] It registers up to nine cats. [src8, src7] Two cautions: PetsRadar's tester could not get it to read her cats' microchips and used the Cat Mate ID disc instead, and Catster says a determined raccoon can pry the flexible flap open. [src8, src7] It is a cat flap, not a dog door.

For Multi-Cat Homes: SureFlap DualScan Microchip Cat Flap — Check price

Expert Reviews' best microchip cat flap for multi-cat households, from its 2024 guide: it reads microchips or a SureFlap collar tag and can be set per cat, so one cat stays in while the others come and go. [src9] Sure Petcare stores 32 pets and quotes up to 12 months from four AA batteries. [src16] It was not in stock on Amazon in our 2026-10-09 price check. It is a cat flap, not a dog door.

Head-to-Head Comparisons

High Tech Pet Power Pet PX-1 (Medium) vs PetSafe Electronic SmartDoor (Large)

Dogster ranks these two first and second, and Canine Journal makes the Power Pet's Wi-Fi version its winner and the PetSafe its budget pick. [src1, src2] The Power Pet opens itself and locks with a deadbolt, but the PX-1 stops at 30 lb and runs on mains power, with a battery only as back-up. [src1, src11] The PetSafe is a battery-powered flap the dog still pushes, opened by a collar key, and its Large size takes dogs up to 100 lb. [src1, src2]

Pick the High Tech Pet Power Pet PX-1 if: your pet is under 30 lb, struggles with flaps, and you have an outlet by the door.
Pick the PetSafe Electronic SmartDoor (Large) if: your dog is bigger, you have no outlet nearby, or you want the cheaper door.

SureFlap Microchip Pet Door Connect vs SureFlap Microchip Pet Door

The same SureFlap pet door with and without the app: both open for an implanted microchip or a SureFlap collar tag and suit large cats and small dogs. [src5, src15] The Connect adds the Sure Petcare app — notifications, remote locking and curfews from your phone — but needs the Hub, sold separately; the plain Pet Door sets its curfew on the door itself. [src5, src15, src4]

Pick the SureFlap Microchip Pet Door Connect if: you want to know when your pet comes and goes and to lock the door from your phone.
Pick the SureFlap Microchip Pet Door if: a curfew set at the door is enough and you would rather not run a Hub.

High Tech Pet Power Pet PX-1 (Medium) vs Power Pet WiFi (Medium)

The same motorized door; the WiFi version adds an app that opens and closes it remotely, runs up to 20 timers and logs its use. [src2, src13] High Tech Pet rates the WiFi Medium for pets up to 25 lb and the PX-1 for pets up to 30 lb. [src13, src11]

Pick the High Tech Pet Power Pet PX-1 if: you just want the door to open for your pet.
Pick the Power Pet WiFi (Medium) if: you want schedules and to let your dog in or out from your phone.

High Tech Pet Power Pet PX-2 (Large) vs Wayzn Smart Pet Door

Both open by themselves for a big dog and both run on mains power. [src12, src10] The PX-2 mounts on a door or wall over a hole the size of its panel; the Wayzn cuts nothing and moves your sliding glass door instead, but fits only two-panel doors with the fixed panel outside, and The Gadgeteer found its motion sensing unreliable. [src12, src14, src10]

Pick the High Tech Pet Power Pet PX-2 if: you own the home and want a sealed, deadbolted door in a wall or door.
Pick the Wayzn Smart Pet Door if: you rent or will not cut into the house, and your sliding door fits it.

Decision Logic

If your pet is a cat or a small dog and you want no collar

→ SureFlap Microchip Pet Door Connect for app alerts and remote locking (Hub sold separately), or the SureFlap Microchip Pet Door for the same microchip entry with a curfew set at the door. [src2, src5, src15]

If your pet is under 30 lb and you want the door to open by itself

→ High Tech Pet Power Pet PX-1 (Medium), or the Power Pet WiFi (Medium) (pets up to 25 lb) if you want app control and schedules. Both run on mains power. [src1, src11, src2, src13]

If your dog is 30-100 lb

→ PetSafe Electronic SmartDoor (Large) for a collar-key flap on batteries, or High Tech Pet Power Pet PX-2 (Large) for a motorized, deadbolted door. [src1, src2, src12]

If you rent or cannot cut a hole in a wall or door

→ Wayzn Smart Pet Door, if your sliding glass door is a two-panel door with the fixed panel outside. [src2, src14]

If you have several cats and must keep one indoors

→ SureFlap DualScan Microchip Cat Flap, which can be set per cat. [src9, src16]

If you want a curfew for cats without an app

→ Cat Mate Elite Microchip Cat Flap (355), after checking with the maker that it reads your cats' microchips — PetsRadar's tester had to use the ID disc. [src8]

Default recommendation (unknown requirements)

→ High Tech Pet Power Pet PX-1 (Medium) for a pet up to 30 lb with an outlet nearby; otherwise the PetSafe Electronic SmartDoor (Large). [src1, src2]

• Pet size splits the category: the outlets recommend microchip flaps (SureFlap, Cat Mate) for cats and small dogs, and collar-key or motorized doors (PetSafe, Power Pet) for anything bigger; Canine Journal rules the SureFlap Connect out as its winner for exactly that reason. [src2, src3, src5]
• One maker owns the motorized door: every dog-door roundup we read includes High Tech Pet's Power Pet, from Dogster's and Canine Journal's top spots to Gagadget's and Catster's premium choices. [src1, src2, src3, src6, src7]
• App control is an add-on: the SureFlap needs a separate Hub to reach its app, and High Tech Pet sells the Wi-Fi Power Pet as its own model next to the standard PX-1. [src5, src13, src11]
• No-cut doors for renters: Wayzn opens an existing sliding glass door rather than adding a flap, Canine Journal's answer for sliding doors. [src2, src14]
• Little hands-on testing: most of the dog-door roundups here choose mainly from research and owner reviews; hands-on reviews exist for the SureFlap Connect (Trusted Reviews, 2018), the Wayzn (The Gadgeteer, 2021) and microchip cat flaps (PetsRadar, Expert Reviews), and Gagadget's writer says he tested his picks. [src1, src2, src3, src4, src10, src8, src9, src6]

• Some picks were hard to buy from Amazon when we looked: the SureFlap DualScan was not in stock in our 2026-10-09 price check, and our checks have found no Amazon offer for the SureFlap Microchip Pet Door since 2026-09-11. Sure Petcare's US pages send buyers to retailers ("Where to buy"). That is a note about where to buy, not a change to the ranking. [src5, src15]
• Motorized doors need upkeep: Dogster says the PX-1 may break down after a year and the company sends parts rather than a new door, and that the PX-2 may need costly repairs. [src1]
• Collar-key doors can misread: Catster found the PetSafe Electronic SmartDoor's sensor "a bit glitchy", sometimes unlocking from 15 ft away and sometimes not opening for a cat beside it, and says metal can block the signal. [src7]
• Microchip doors only read compatible chips. Check yours with the maker before buying; PetsRadar's tester could not get the Cat Mate Elite to read her cats' chips. [src8, src15]
• Most rankings here come from research-based roundups rather than lab tests, and two outlets (Dogster, Catster) refused our requests, so we read their pages from Internet Archive captures of July 2026. [src1, src7]
