Former Sgt. William Cole's 29 months as a special ops solider in Iraq and Afghanistan left him with a traumatic brain injury and post-traumatic stress disorder.

He says the only thing that helped him was his service dog, Hank.

So when Hank was hit by a car and given a 50/50 chance of survival, Cole knew he had to save his dog's life, no matter the cost.

Cole explained on "Fox and Friends Weekend" this morning that four deployments had taken a major toll on him.

Medication and therapy weren't working, so he decided to try a service dog, adopting Labrador Retriever Hank when he was a 10-week-old puppy.

"It ended up being the best decision I've ever made," Cole said.

He explained that several months ago, Hank escaped from the backyard through a cracked gate and was hit by a car.

Luckily, he was taken to a veterinary hospital quickly, which likely saved his life.

With a fractured C4 in his spine, two broken scapulas and a significant portion of his left lung removed, Hank's medical bill stands at $11,000 and could continue to grow, as he could need ongoing care.

Cole said that a doctor's appointment on Wednesday at the Texas A&M Veterinary Hospital will determine what happens next.

"He's a young dog, so he definitely has the will and the drive to get better," Cole said.

The special ops veteran started a GoFundMe fundraiser to help pay for his dog's exorbitant medical bills.
