UPDATE: Mr Warhurst says he is out of words over the public support he has received in the past few days.
"I'm most astounded," he said. "I can't thank the people enough for their support.
"I'd like to thank the people at McIvor Road Veterinary Centre, and Sue in particular.
"When I got there this morning one lady was almost in tears."
Mr Warhurst said when he arrived at the vets he was handed a blue bag with a teddy bear and card.
"It was the most beautiful blue bag with a new teddy bear. The card was from a Jaclyn. I don't think she knew Raz had died."
More than 50 people have taken to Facebook this morning to leave a tribute for Raz.
Darise Birrell wrote, "Bless his little heart so sad", while Selina Mullins commented, "Oh no, how heartbreaking when he was thought to be coming home soon. Condolences to Ian, RIP Raz."
EARLIER: "Little legend" Raz has passed away this morning.
The 22-year-old Maltese was attacked by two Staffordshire bull terriers on Wednesday in Huntly and was on life support at the vets for almost three days.
Raz's owner Ian Warhurst said he got the call about 8.30am this morning.
"He battled, he had a heart as big as a lion," Mr Warhurst said.
"He battled and battled and battled but the battle was too great."
Mr Warhurst said he would lay him to rest today.
