Just one month ago, Greg Manteufel of Wisconsin was a long way from a hospital bed.
However, when bruising appeared on his arms and legs, the 48-year-old was rushed to the emergency room.
Within a week, doctors told the husband they had to cut off his legs - as the disease, which caused Manteufel's blood pressure to plummet and the circulation in his limbs to dramatically decrease. His wife Dawn says he told the doctors to do whatever they needed to keep him alive.
The bacteria, called Capnocytophaga canimorsus, "just attacked him", Dawn said, and it did so quickly and aggressively. His wife, Dawn Manteufel, said he was perfectly healthy.
As for the Capnocytophaga Canimorsus bacteria, this one is rarely causing such severe infections when contracted through saliva and without getting bitten by a carrier. Up to 74 percent of dogs have the bacteria and 57 percent of cats have it.
Doctors said the infection was likely caused by being licked by his dog.
Several types of Capnocytophaga bacteria, according to the U.S. Centers for Disease Control and Prevention, "live in the mouths of dogs and cats".More news: INDIA Assam, 4 million people deprived of citizenship, at of risk deportation

In very rare cases, a person can get infected without being bitten. Infections can take up to two weeks to show up.
The faster the infection is diagnosed the better the chance of survival. Approximately 30% of people who get infected die, some within a day of symptoms first showing up.
What makes both these cases unusual is that neither was bitten by a dog, which is a more common form of transmission. "People with weakened immune systems include, for example, those who drink alcohol excessively, who have had their spleens removed, and who have HIV infection or cancer", according to the CDC.
Within a week, Manteufel's legs were amputated from the knees down.
Unfortunately, he lost his legs up to kneecaps and both hands, up to mid-forearm.
A GoFundMe page has been set up by Manteufel's family, which was already near at $25,000 goal at the time of writing.
