This is a specific conversation about GPS pet trackers — peace of mind if they escape — ask about yours and get one honest answer for your exact situation.

Greyhounds and standard collars are a notoriously bad match — that narrow, tapering neck means most trackers slide straight off the moment they pick up speed, which is exactly when you need them most. GPS trackers are genuinely worth it for sighthounds, but the fitting problem has to be solved first or you're just throwing money away. To point you in the right direction: is your greyhound slipping the lead during runs, or more of a bolter when startled? And are you in a rural or semi-rural area? That affects which tracker makes most sense on the coverage side.
She's a bolter when she catches a scent — we do a lot of off-lead running in the countryside and twice now she's gone a long way before stopping. Rural Shropshire, so not the best signal. She's microchipped already.

That's a classic greyhound scenario — sighthound locks onto something and she's gone before you can react. Good that she's microchipped, but a chip only helps once someone finds her; a tracker means you can go and find her yourself. Shropshire is patchy for mobile signal, which rules out a few of the cheaper trackers that rely purely on 4G. Before I suggest a specific device — what does she currently wear, a flat collar or a martingale? That matters a lot for how we solve the slipping problem.
She's been on a flat collar but I've been thinking about switching to a martingale. I just don't want to go through another tracker falling off mid-run.

Switching to a martingale is exactly the right call for a greyhound, and it solves the tracker problem at the same time. Here's what I'd recommend: the Tractive GPS DOG 4, attached to a Houndworthy or similar wide martingale collar. The Tractive is one of the most reliable trackers for rural UK use — it runs on multiple networks simultaneously rather than locking onto one, so it handles patchy Shropshire signal better than most. The tracker clips onto the collar loop, and because a martingale tightens slightly under tension, it won't slip over her head during a sprint. The app gives you live tracking and a trail history, which is genuinely useful if she's run a long way and you're trying to work out her direction. There's a subscription involved — around £5 a month — but for a dog that bolts in open countryside, it's worth it. Avoid mounting it on a flat collar regardless of which tracker you choose; that's always going to be a problem with her neck shape.
Does the Tractive work if she goes into a valley or a heavily wooded area?

It'll lose the live signal if she's in a deep valley with no mobile coverage, yes — no tracker avoids that entirely. What the Tractive does better than cheaper alternatives is reconnect quickly once she moves back into signal range, and it logs her GPS trail even during the drop, so when the signal comes back you can see where she went. For Shropshire countryside that's probably the best you'll realistically get. The main thing is that you'll know her last confirmed location and the direction she was heading, which is far better than nothing. Pair that with the martingale so it stays on during the run, and you're in a much stronger position than you are now.
