ROBERTS, Wisc. - Carrie Fisher no longer allows her husband to finish a sentence that starts out sounding like, "It can't get any worse."

Eric Fisher – a veteran of six military deployments in seven years – has also endured a heart attack, Post Traumatic Stress Disorder and cancer.

"Don't ask what else can happen," laughs Carrie, "we don't go there."

Eric, an Air Force reservist, was deployed in Afghanistan in 2011 when the unthinkable happened.

"We had a rocket attack at the base and I had a heart attack during that," Eric explained. He was 44 years old at the time.

Eric was flown to a military hospital in Germany where two heart stents were inserted.

He arrived back home in Roberts, Wisconsin - and returned to work.

"I had a very big anxiety attack my first day back," Eric said. His anxiety worsened. Going out in public became more and more difficult. Eric was diagnosed with Post Traumatic Stress Disorder.

But his ordeal still wasn't over. In December of 2013 Eric went to the doctor with a pain in his side and was diagnosed with Hodgkin's Lymphoma.

Still undergoing chemo when he retired from the Air Force earlier this year, Eric needed some good fortune. He got some in a trained service dog named Lola.

Lola, a two-year-old Springer Spaniel Labrador mix, now alerts Eric's family when he's in trouble by pulling a rope on a monitor he wears on his belt.

She's eased his comfort level in crowds by creating a buffer between Eric and others.

Lola has even been trained to wake Eric when he drifts into night terrors, a symptom of his PTSD.

"Just last night Eric was waking up and stirring a little bit and there she was laying right on top of him," said Carrie.

For Eric it mean not having to "relive whatever I'm reliving, so she helps with that."

Eric gave his service, now Lola is giving hers.

Note: Lola's training is expensive. Eric Fisher's service dog cost $15,000. Two-thirds of that was paid by an anonymous donor. Eric and his friends are trying to raise the rest.
