Pets · village and countryside

So you never have to put up this poster.

A light collar and a small box at home. If your dog gets out, your phone alerts you right away and shows you which way it's heading. No SIM card and no monthly fee: you pay once.

  1. 10:02

    Toby, at home.

    You mark on the map where your dog is allowed to be: the house, the garden, the field. The box at home keeps watch for you.

  2. 10:17

    Over the fence.

    As soon as Toby leaves that area, your phone gets an alert. Not an hour later: right away.

  3. 10:18

    You know which way.

    Distance and direction on the map, even if the mobile signal in the village is poor.

  4. 10:23

    And you find him.

    You head out with the receiver in your pocket and go straight to him. Six minutes, not a whole afternoon.

Rastro Kit: 1 Rastro Collar, 1 Receiver, Charging cradle
The kit

Collar on the dog. Receiver at home.

The same system hunters use for their dogs, with a lighter collar for family dogs (in development). The receiver stays at home and alerts you if your dog wanders off.

Family-dog version in development: price to be announced, no fees, ever.

No fees: the app is free, forever.

Where it shines. And where it doesn't.

Yes
  • Village house with a yard or vegetable garden
  • Farm or country house
  • House with a garden on the edge of town
  • Walks in the countryside with no signal
Not so much
  • Right in the centre of a city, among tall buildings

There, radio reaches less far and a SIM tracker suits you better. We'll tell you straight.

Pets · after the hunting version

Join and we'll let you know.

How much does the collar weigh?

The hunting collar is being finalised now. For family dogs we'll make a lighter version; we'll publish weight and size once they're decided.

Do I need wifi at home?

To find your dog, no: the collar and the receiver talk to each other by radio. For alerts to reach you when you are away from home, yes, you need your home wifi.

Is there a fee?

No. Not monthly, not yearly, not for the app. You pay for the collar and the receiver once.

When will it be out?

After the hunting version, which is the one we're testing this season.

Does it work outside Spain?

It uses radio frequencies that are licence-free in Europe. Outside Europe the rules are different, so we can't promise it yet.
