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, where the dogs were introduced with a cattle herd on the Rita Blanca National Grasslands this summer. Conservationists believe fewer than 250 swift foxes remain in Texas.
Why it matters
Coyote predation is a leading cause of swift fox mortality, and the species occupies only about 40 percent of its historic range. A nonlethal approach that protects both foxes and livestock could offer a model for coexistence on Texas rangelands.
The swift fox, about the size of a house cat, is believed to have fewer than 250 individuals left in Texas. Whether the guardian dogs will measurably cut coyote predation remains unknown until the three-year GPS-collar study concludes.
The players
Texas A&M University
A public research university whose researchers are conducting the study on guardian dogs and swift fox mortality.
Rita Blanca National Grasslands
A federally managed grassland in the Texas Panhandle where the guardian dogs and cattle herd operate alongside swift fox habitat.
The details
Livestock guardian dogs were paired with a cattle herd on the Rita Blanca National Grasslands in Dallam County, the only known Texas county with a swift fox population. Researchers are using GPS collars on coyotes and swift foxes to track animal behavior, and the producer involved has not lost any calves to predation so far.

Big Picture
The project tests a nonlethal predator-deterrence method against a species that now occupies about 40 percent of its historic range. It extends ongoing swift fox conservation work in the Texas Panhandle into a test of livestock protection techniques.
Ranchers and pet owners in the Texas Panhandle may find nonlethal predator-control methods relevant to protecting livestock. The findings could shape how working dogs are used on rangelands in the future.
The takeaway
Working dogs can serve dual roles, protecting livestock while also supporting the survival of vulnerable wildlife species. Watching how the three-year study unfolds could offer useful lessons for rangeland managers across Texas.
