A MAN who had his genitals ripped off "and eaten" in a horrific dog attack was seen walking a bulldog just days earlier, The Sun Online can reveal.

The 22-year-old, who we are not naming, is fighting for life in a coma after being discovered unconscious lying in a pool of blood in a flat on Sunday.

Emergency crews raced to a flat in Haddington, East Lothian, just after 2.30pm and found the victim lying on the floor with sickening wounds.

He was rushed to Edinburgh Royal Infirmary where medics have been working around the clock battling to save him.

Shocked neighbours told The Sun Online today they had seen the man walking a bulldog just days before.

A shopkeeper at Betty's of Haddington said: "I saw him walking the dog a few days ago through the high street."

There were fears today the dog may have eaten the organs — making it impossible for them to be reattached.

Police Scotland said today they are investigating after “a man suffered serious injuries believed to have been caused by a dog”.

A spokesperson added: “Emergency services were called to a property in the High Street area at around 2.30pm.

“A 22-year-old man was taken to the Edinburgh Royal Infirmary by the Scottish Ambulance Service.”

They said he was later transferred to the Western General Hospital where he continued receiving treatment this week.

No arrests have been made as cops were unable to speak to the "seriously injured" victim while he was unconscious.

There has been no police update on the victim's condition today.

The dog is thought to be a Bulldog-type crossbreed.

Reports say the dog involved in Sunday’s attack has been placed in a kennel.
