Should ranchers use guardian dogs to protect wildlife like swift foxes?
Texas A&M researchers are studying whether livestock guardian dogs can reduce swift fox mortality in Dallam County. The dogs were introduced alongside a cattle herd on the Rita Blanca National Grasslands in summer 2026, as part of a three-year project.
Why it matters
Coyote predation is a leading cause of swift fox deaths, and fewer than 250 swift foxes are believed to remain in Texas, so the project tests whether guardian dogs can change coyote behavior and protect a rare native species. For Texas Panhandle ranching families, the same approach could also reduce calf losses during calving season.
The swift fox is about the size of a house cat, and conservationists believe fewer than 250 remain in Texas. The producer involved in the project has not lost any calves to predation so far.

The details
Livestock guardian dogs are paired with a cattle herd on the Rita Blanca National Grasslands, where they are expected to act as a larger predator that changes coyote behavior and habitat use. Coyotes take advantage of taller vegetation cover, which increases predation on swift foxes, so the dogs' presence is hoped to deter coyotes. Researchers are monitoring animal behavior by placing GPS collars on both coyotes and swift foxes. Swift foxes do not pose threats to cattle, sheep, or goats.

The Home Front
Swift foxes now occupy about 40 percent of their historic range, which reaches north into Alberta, Canada. For Panhandle ranch households, predator losses are a recurring cost tied to calving season and herd management.
If you keep livestock or manage rural acreage in the Texas Panhandle, consider whether guardian dogs fit your operation and ask a local extension office about working-dog options. Keep records of any calf or livestock losses so you can compare them against future predation trends.
The takeaway
Guardian dogs are being tested as a non-lethal way to protect both livestock and a rare native predator. Panhandle ranch owners interested in the approach can start by asking their local extension office about working-dog programs.
