An elderly man who was set upon by vicious dogs in Northland late last year has again been the victim of a dog attack that's left him rattled and injured.

The latest ordeal occurred on the same Kaikohe street as the first incident, and comes just 54 days later. In the first attack, Jim Morgan's dog Sandy was so wounded that he was forced to put her down.

This time, Mr Morgan suffered a nasty bite on his hip and went into shock after allegedly being set upon by two "bull terrier-type dogs" on Monday, according to a neighbour.

The 95-year-old is legally blind and profoundly deaf, meaning he has little opportunity to protect himself when attacks do occur.
