Stem cells are taken out of the dog's fatty tissue are harvested then injected into problem areas leaving the dogs completely healed.
"We couldn't take him on walks..he just laid around a lot," said Keith Nosowiak, Deniro's owner.
"We'd hear whimpering overnight... she'd take a few steps and she would sit down," said Luther Kortbein, Shadow's owner.
Until two months ago, Deniro suffered from severe arthritis, Shadow from hip displaysia.
Deniro's owner thought he may even have to put his German shepherd down.
"We felt we had a decision to make with his quality of life and being in pain we didnt want him to be in pain," said Noskowiak.
Shadow's owner was willing to try anything to cure her.
"Whatever the cost needed to get this done we were willing to do," said Kortbein.
Then Packerland Veterinary Center offered them stem cell therapy by using the dogs own stem cells and then injecting them back into the bloodstream joints.
"This is just the tip of the iceberg. Pretty soon I thnk we will be able to us this to regenerate more than just part of a tendon," said Veterinarian, Maura Mansfield.
The stem cell procedure proved to be a miraculous recovery for both animals.
