Greater Dandenong Crime Investigation Unit detectives are investigating an assault and attempted theft of a dog in Dandenong last year.
It is understood the victim was walking his dog west along the Princes Hwy about 6pm on November 27.
The 25-year-old Dandenong man was approached by two unknown men who asked to pat his Husky. The men then asked how much the dog would be to purchase.
When the victim told the men it was not for sale, they grabbed the leash and attempted to take it from the victim.
The victim was then punched to the face a number of times.
As the victim left the area he dropped an amount of cash, which the offenders then picked up before leaving.
A short time later the victim was again confronted by the two men.
He was chased across the Princes Hwy and M2, before being assaulted with a stick.
The Dandenong man sustained injuries to his head and upper body.
Investigators have released CCTV of two people they believe may be able to assist with their investigations.
The first man is described as African, aged in his early 20s, with a slim build and black braided or dreadlocked hair.
He was wearing black track pants and white shoes, carrying a yellow soccer ball.
The second man is described as Caucasian, aged in his mid to late 20s, with an average build and short black hair.
He was wearing a red baseball hat, black hooded-jumper with a white motif and blue trackpants with white stripes.
