PHOENIX (3TV/CBS 5) - Sammye Darling doesn't do this for the money or seek out attention.
The Valley dog trainer has made it her mission to help veterans and others with disabilities.
"It's a lot of training," said Darling. "These guys have over 300 hours of training before they are placed, so they'll know over 50 commands."
Darling has been a trainer with the nonprofit National Assistance Dogs for the past 10 years.
It's a group devoted to helping vets overcome PTSD and other ailments by providing them with a highly trained companion.
"I have people that haven't left the house for years, then suddenly in 6 months they are going out every week," said Darling. "It's an improvement and gives them independence again to go back out there and take on life in America."
Katie Eubank volunteers with Darling and has seen how much time she spends trying to raise money to help vets who need service dogs.
Eubank reached out to CBS 5 to Pay It Forward to the devoted dog trainer.
"I really wanted to be able to help her, and financially, I couldn't, so I just reached out to see, not expecting ever to get the phone call," said Eubank.
A CBS 5 news crew followed Eubank as she showed up one day to surprise Darling and give her $500.
"I just want to say you have had some car trouble lately, and you've done so much for me," Eubank said. "You're doing so much with these dogs and the community and for veterans that have PTSD. You're making a difference in people's lives, and I reached out to Channel 5 news, and they have generously picked us to give you $500."
"She's doing a good thing," said Eubank. "It's nice when the community can hug back, and say, 'I'm here to help you.'"
