A man has died after being attacked by his own dog.
The 22 year old, named on Facebook as Liam Hewitson, was bitten by the animal in Preston, Lancashire Police said.
He was treated by paramedics at a terraced house in Dundonald Street, but subsequently died from his injuries.
One young man, who said he was the victim's cousin, said "he had an epileptic fit" at the time of the attack.
The victim's girlfriend Jessica Hill told the Daily Mail she had "no words".
"I'm too devastated to speak. I just love and miss him so much," she said.
She paid tribute to him on Facebook, saying: "Rip my baby boy love you forever & always babe."
Chantelle Hewitson, 25, from Ingol, Preston, also a cousin of the victim, said: "Everyone is in shock he was such a good lad so respectful it's heartbreaking.
"We will always love him and keep him in all our memories."
Groups of youths left bunches of flowers at the scene.
Two bouquets of flowers had been tied to a nearby lamppost as police cars lined the street.
Police have not specified what breed of dog was involved but reports suggested it was a pit bull terrier named Tiger. It was taken from the address and put down by a vet.
One man said he had been "like a father" to the victim but refused to say any more.
On Facebook, Mizzy B Saeed wrote: "Tragic news Saw liam shortly before the incident. Exchanged hi/hello Awful news hasn't sunk in yet. Thoughts and prayers with his family (Liam's neighbour)."
Ms Hewitson wrote: "Rest In peace little cousin so heartbreaking you with your beautiful mum now Liam rest in paradise love you always xxxx".
Another said those wanting to pay their respects would be lighting candles in the street.
Detective Inspector Jane Webb of Preston CID said: "This is a tragic incident in which a man has sadly died.
"Inquiries are ongoing to establish the exact circumstances and my thoughts very much remain with his family who are being supported by specially trained officers at this time."
