James Little told The Associated Press on Friday that he is "doing fine" and resting, but he declined to speak further.
Little called 911 on Tuesday to say his dog had eaten part of his right foot while he was sleeping, including three toes.
The hospital says Little is in fair condition and was expected to go home Friday.
Little had no feeling in his feet because of diabetes.
Roseburg veterinarian Alan Ross says the dog may have been trying to rid his owner of dead tissue, which is not uncommon.
The dog is at an animal shelter.
