DENISON, Texas (KTEN) — Staff with a North Texas non-profit are teaching veterans how to train their dogs as service animals.

Faithful Friend works with pooches of all different levels, training them to combat hardships veterans face like post-traumatic stress disorder.

The organization currently has a presence in Collin and Grayson counties, and organizers hope to expand to help veterans in Rockwall, Fannin and Kaufman counties.

"I've had a bunch of stress and trauma through my life, through my military service and police work," said Army veteran Jameson Miller. "A lot of that stuff has cropped up in my life and caused difficulties. My service dog has blocked a lot of that out and gotten me past a lot of that... doesn't let me fall into the trap, and that's thanks to the training that we get here at the Walker House with Faithful Friends."

Faithful Friend offers free classes on Monday's at Walker House in Denison.
