The 61-year-old was tracking a deer, which had been injured in a traffic accident.
When his dog found a dead rabbit instead, it became aggressive and attacked the man.
The hunter was able to tie the animal to a traffic sign and alert the police.
When the officers arrived, the badly wounded hunter asked the police to kill his dog in order to prevent further danger.
The animal was killed with two shots and the hunter taken to hospital with serious injuries to his hands, legs and abdomen.
