About Us

Owned by Rob & Devon Harrison, Diamond H Ranch are proud owners & breeders of Peruvian Horses & Belted Galloway Cattle.

Rob's family has been ranching in East Texas since 1791. The Harrisons are proud supporters of their local 4-H and FFA groups, frequently purchasing at their auctions to support the agricultural youth in their area.

Devon is a very successful amateur competitor in the Peruvian horse breed, showing her horses across the United States. Starting with one Peruvian gelding 10 years ago, LEA Marco Polo, their herd has now grown to 8 and one foal coming in 2023.

Belted Galloway Cattle

We have been raising Belted Galloway cattle on the Diamond H Ranch since 2009 and today have one of the finest most genetically diverse hearts in North America. A full Registry of our herd is available at https://www.clrc.ca/search-registry/member-details/5359504.


We specialize in raising organic grass-fed beef and generally have steers available for sale and provide custom beef processing to your specifications. 


We have a broad selection of Black, Red, and Dun cattle and have bulls, cows, and calves available for sale in all color phases of the breed. You are always welcome to visit us at the Diamond H (reservations are required). We can deliver our cattle anywhere in North America for an additional charge. 


The Diamond H Ranch is a life member of the Belted Galloway Society belted.org and a proud sponsor of the Newton County Fair Association, FFA and 4-H.
