A service dog that has come from the brink of death and back was in Terry on Wednesday to receive cutting-edge stem cell therapy.

Davis Hawn said his dog, Booster, saved his life and now he's working to return the favor.

"With Booster by my side, I greet each day knowing we can change the world for the better," Hawn said.

Together, Hawn and Booster helped foster international relations by appearing on TV in Cuba. They reassured Thai orphans infected with the HIV virus that life will be OK and they are loved. The list of accomplishments continued to grow until Booster developed hip dysplasia.

"When Booster couldn't get off the floor, I couldn't get out of bed," said Hawn, who suffers from depression. "Just as assuredly as God put Booster into my life, He again answered the call when I read about the modern day marvel of stem-cell implantation."

Medivet America, a global leader in veterinary science with more than 1,000 clinics in 28 countries, learned of Booster's plight and jumped in to help.

"They arranged to perform a procedure in which they injected Booster's own stem cells into his hips and got him back up and running again," Hawn said. "When I went to pay the bill, they refused to accept payment. I like to say that God paid the bill."

In January 2013, Booster again faced a health battle. He was diagnosed with squamous cell carcinoma and given three weeks to live. An aggressive tumor had eaten through Booster's skull cap and left him writhing in pain. In an effort to save Booster's life, Hawn moved to Florida where the University of Florida operated on Booster and a referral clinic performed radiation therapy.

The University of Minnesota took a piece of the tumor that was removed from Booster and used it to developed the first vaccine for squamous cell carcinoma in dogs.

Booster is now a cancer survivor.
