GPS dog collars: how they work and are they worth it?

There’s no way to guarantee that a dog will never run away — there’s always a gate that’s not properly closed or a sudden scare that sends him dashing off. What you can do, however, is find him quickly. A GPS collar lets you know where your dog is in real time, even when you’re not at home, and is one of the most effective tools for reducing the time spent searching when he goes missing.

How a GPS collar works

The device, attached to the collar, uses satellites to calculate the dog’s position and sends this information to a mobile app via the mobile network. Instead of wandering round calling out its name, you open the app and see its location on a map.

What sets GPS apart from a microchip

They are complementary, not substitutes. Microchipping is compulsory in Portugal and identifies the dog when someone finds it and takes it to a vet — but it is passive. The GPS collar is active: it allows you to track the animal in real time, which makes all the difference in the first few hours after it has run away.

Features that make a difference

• Real-time tracking — you can see their position on the map at any time.
• Geofencing (safe zones) — you define an area (home, garden, park) and receive an alert if your dog leaves it.
• Movement history — you can see your dog’s routines and where it usually goes.
• Behaviour alerts — unexpected movement or prolonged inactivity.
• Water resistance — essential for dogs that get wet or play outdoors.

What to consider before buying

Key considerations:

• Connection type: 4G GPS collars work anywhere with mobile network coverage. Bluetooth alternatives (such as Bluetooth trackers) have a limited range.
• Battery life — having to recharge every day is a hassle with models that have a short battery life.
• Weight and size — it should be light enough for the dog’s size.
• Subscription costs — some models require a monthly subscription. Check before buying.

What about cats? There are options

There are also lightweight trackers compatible with device networks (such as Apple Find My) that work well for cats and small dogs, although with less accuracy than a 4G GPS.

A GPS collar is no substitute for responsible ownership, but it gives you peace of mind knowing where your dog is — and in the hours following a runaway, that’s exactly what makes all the difference. 🐾
