A Wisconsin man's limbs were amputated after doctors said he contracted a bacterial infection – likely from a dog's lick.

According to WITI, Greg Manteufel, 48, of West Bend, believed he had the flu when he went to the emergency room in late June. But doctors later determined that capnocytophaga, a type of bacteria found in dog saliva, had caused the infection that left him bruised, dropped his blood pressure and decreased blood flow to his limbs.

To keep Manteufel alive, doctors had to amputate both legs to the knees and both arms to the mid-forearm, according to a mid-July update to a GoFundMe page for the family. That campaign has raised more than $27,000.

Manteufel's wife, Dawn, told WITI that her husband has "been around dogs all of his life."

"We can't wrap our heads around it," she said.

Dr. Silvia Munoz-Price, who specializes in infectious diseases, told WITI that "99 percent of people that have dogs will never have this issue."
