(9News) A UK man is in a critical condition after having his genitals completely bitten off in a dog attack.

At about 2.30pm on Sunday, paramedics found the 22-year-old unconscious and lying in a pool of his own blood in a unit on High Street, Haddington, on Scotland’s east coast.

The man was at a party at the location when an English Bulldog, believed to be his, attacked his groin.
