Kathy, who has been a registered nurse for more than 30 years, said she could see the brachial artery, bone and tissue exposed on Nave's arm.
"His arm was dangling, it was just hanging there. The more blood it pumped, the whiter he got. I could see him fading, the terror in his face. I tried to do the best I could do for him because I was worried for his life."
Nave was transported to Mercy Medical Center and later transferred to University of Iowa Hospitals and Clinics in Iowa City.
According to a family member, Nave has already had one surgery and suffered nerve damage in his right arm. The family member did not know the extent of the damage in Nave's left arm, but said he will need further surgeries because of his injuries.
Both dogs fled the scene, with one located a short time later and killed by police. Officers were unable to locate the second dog.
Bohle advised anyone who sees the wounded pit bull to contact the Clinton Police Department at 243-1458. He also advised not to engage the dog in anyway.
