The Guard Dog ALGDDS1000W Door Stop Wedge Alarm is a portable door alarm for travelers, students, and anyone who wants an extra layer of security on a door that isn't theirs. It slides under almost any door and sounds a 128-decibel siren the moment that door is pushed open. At under 3 ounces and 5 inches long, it drops into a carry-on or a backpack pocket without adding bulk. There's no installation, no wiring, and no app to configure. For hotel rooms, dorms, and short-term lodging where you can't change the locks, this dog door alarm gives you an audible warning and a physical wedge in one device.
The wedge body uses a woodgrain finish over a plastic blend, with an anti-slide rubber base that grips the floor so the unit doesn't kick out when a door makes contact. Built-in sensors trigger the 128 dB alarm when the door opening lifts or shifts the wedge. An on/off switch keeps it from sounding accidentally while you position it or pack it away, so you arm it only when you're ready. The whole thing measures 5 inches in length and weighs less than 3 ounces, which is light enough to forget it's in your bag until you need it. Guard Dog backs the unit with a lifetime warranty. It runs on its own internal power with no external cables to route.
Wedge it under your hotel door at night and the alarm does the work of warning you and startling anyone trying to force entry. The same setup works in a dorm, a rental, or a home office where you want a low-cost deterrent without drilling holes. It pairs well with a personal alarm or a compact light for travel, and we stock both alongside other security electronics and everyday accessories.

The alarm sounds at 128 decibels per manufacturer specifications. That's loud enough to wake you from sleep and alert anyone nearby, while startling a person attempting to push the door open. The siren triggers automatically when the door shifts the armed wedge.
No. The ALGDDS1000W needs no tools, screws, or wires. You place the wedge under the door, flip the on/off switch to arm it, and the built-in sensors do the rest. This makes it well suited for hotels and rentals where you can't modify the door.
It slides underneath nearly any standard door with enough floor clearance. The anti-slide rubber base grips the surface so the wedge holds position when the door makes contact. Very tight thresholds or thick carpet may reduce clearance, so check the gap under your door first.
The unit measures about 5 inches in length and weighs less than 3 ounces. It packs flat into a carry-on, backpack, or laptop bag without adding noticeable weight, which is part of why it's built for travel security.
Guard Dog covers the Door Stop Wedge Alarm with a lifetime warranty. Keep your proof of purchase and contact the manufacturer through their warranty process if the unit fails under normal use.
