Strip Grazing with Front and Back Fencing - All Managed from Your Phone

Collie is built with farmers in mind.

We understand the daily pressures farmers face - balancing productivity, animal welfare, rising costs, and meeting environmental regulations.

That’s why we’ve designed technology that makes your work easier, more efficient, and ultimately more rewarding.

The collar

Built to last and Easy to Use

Virtual Fencing and Herding: Collie’s smart collars use sound and vibration cues to gently guide cows.

Audio signals indicate when cows approach virtual fences, while vibration guides them to the barn or milking station.

A brief pulse reinforces boundaries - only if necessary, after multiple warnings - to ensure stress - free management.

FAQ

Question about our product?
Maybe we have already answered it.
Are there other situations where the collars might temporarily stop working?

Yes, there are several scenarios:

  • Manufacturing defects in the collar.
  • Software bugs that can affect performance.
  • Moisture ingress causing temporary electronic failure.

In most cases, you'll receive a notification via the app, and you should have spare collars available to replace the non-functioning one.

How often does the system fail due to telephone network issues, and what happens to the cows during such outages?

Such failures are rare and typically short-lived. As network technologies improve, both the frequency and duration of these outages are expected to decrease. During an outage, the collars stop functioning, allowing cows to cross virtual fences. This might lead them into undesirable parts of the field, but they rarely leave the field entirely, as the herd's environment appears unchanged to them.

Can Collie be used when cows keep their calves?

Yes, the calves don’t require collars themselves, as they naturally remain near the cows.

Can you encourage cows to seek out the new boundary?

Yes, the absence of sound signals guides cows to discover the new boundary, encouraging exploration and adaptation.

How do cows know when a fence has been moved?

Cows naturally detect the absence of sound signals and explore the new boundary on their own.
