GPS tracker for escaping Leonberger

A Leonberger finding and using a gap in your estate fencing twice a week is genuinely worrying — these are big, powerful dogs who can cover ground fast once they're out. GPS trackers are one of the most useful tools for exactly this situation: they won't stop him escaping, but they mean you know where he is within seconds rather than spending an anxious hour searching the neighbourhood. Worth knowing upfront: they need a monthly subscription (typically £4–8/month) and rely on mobile network coverage, so they work best where you have a decent signal. A couple of quick questions — is he microchipped, and when he gets out does he tend to wander locally or does he go further afield?

Good — microchip is the essential baseline, glad that's covered. Half a mile to a park and then potentially further following a scent is a real retrieval challenge with a dog his size. For your situation I'd go with the Tractive GPS Dog LTE tracker. It gives you live tracking that updates every 2–3 seconds when you switch it into live mode, so you can watch him moving in real time on your phone rather than getting a position snapshot every few minutes. It also has a virtual fence feature — you can draw a boundary around your property and get an alert the moment he leaves it, which with a twice-a-week escapee means you're getting notified fast rather than discovering he's gone when you look out the window. The subscription is around £4.99/month. One thing: is he wearing a collar or harness day-to-day? The tracker clips onto either, but I want to make sure it'll sit securely on him.

A wide martingale is actually a great base for it. The Tractive LTE attaches with a loop that fits collars up to around 28mm wide, and most martingales sit within that. Given his size and the fact he's an active dog pushing through gaps in fencing, I'd double-check the fit once it's on and make sure it's not flopping around — you can thread a small cable tie through the loop for extra security if needed. The unit itself is lightweight enough that he won't notice it, which matters with a dog who might object to new things on his collar. The battery lasts 2–5 days depending on how much live tracking you use, so if you're checking his location regularly when he's out in the garden, charge it every couple of days to be safe.

You set the virtual fence once in the app — draw the boundary around your property, save it, and then it runs automatically in the background. Every time he crosses that boundary you get a push notification on your phone straight away. You don't have to do anything after the initial setup. The app also keeps a history of his routes, so after a few escapes you'll probably see a pattern — which direction he heads, how far he goes — that can help you work out where the gap is if you haven't found it yet. The Tractive GPS Dog LTE is the one to get — it's the current model with the LTE connectivity that gives you the fastest location updates.

Good — it should make a real difference while you're sorting the fencing. Once you've got it set up, the route history after his next escape is genuinely useful for pinpointing exactly where he's getting out. Hope it's a short-term solution and the gap gets fixed soon, but good to have it as a backup regardless.
