Dead dog actually alive after Vic hit-run

A man is in hospital with serious injuries and his dog is fighting for life in a hit-run incident in Melbourne.

The 44-year-old and his dog were waiting at traffic lights in Footscray about 8.30pm on Sunday when they were struck on Ballarat Road, near Gordon Street.

The car ran into the front of a shop and its four occupants ran from the scene before the man was taken to hospital. No one in the shop was injured.

Police arrested a 48-year-old man and 27-year-old woman, both from Footscray, about 10pm. They are assisting police with their inquiries while the search continues for the other two.

Police originally declared the dog dead but on Monday afternoon the force confirmed the labradoodle was alive but in a critical condition.
