Through a blood test, doctors diagnosed the Wisconsin resident with an infection caused by Capnocytophaga canimorsus, a bacteria often found in dog and cat saliva.
A biker lost both his legs and nose after his pet dog gave him a friendly lick and gave him a rare bacterial infection.
This type of infection is particularly nasty - it can cause death within 72 hours, so the CDC urges people to be aware of the symptoms.
That response caused Manteufel's blood pressure to drop, and the circulation in his limbs to decrease rapidly.
"Rarely, Capnocytophaga species can spread to humans through bites, scratches, or close contact from a dog or cat and cause illness". Doctors were forced to amputate his legs through the kneecap, and damage to his hands necessitates amputation of fingers.
Manteufel has undergone several surgeries to amputate his legs and arms.
Infection can usually be treated effectively with antibiotics and is recommended for a minimum of three weeks. Then doctors had to remove his hands.
This happened so severely in Manteufel's case that doctors saw no other option but to start removing his limbs. "We can't wrap our heads around it", Dawn said.
After discovering the Manteufels have a pet dog named Ellie, the medical staff told Dawn that her husband likely was infected after being licked. She said she didn't know which dog carried the bacteria, but that he had been around eight dogs at the time he got sick, including one that belongs to the couple. It's not clear which dog was carrying the bacteria.
"He just kept saying, 'Take what you need, but keep me alive, ' and they did. This infection in his blood triggered a very severe response on his body", said Dr. Silvia Munoz-Price, an infectious disease specialist with Froedtert and the Medical College of Wisconsin. "It's just chance", Dr. Munoz-Price added.
"Furthermore, all areas of Greg's body and tissue was affected by the bacteria and the sepsis, the [doctors] say his nose will need extensive repairs, which means he will need plastic surgery to rebuild a new healthy nose", a post on the family's GoFundMe page said.
"More than 99 percent of the people that have dogs will never have this issue", she said.
