Sam Lawton, 27, was walking his border terrier, Beth, when the pair came under attack in Heywood, Greater Manchester.
"PIT AND RUN" - OWNER FLED WITH VICIOUS DOG AFTER ATTACK
He claims the out-of-control dog's owner swore at him and told him not to call the police before running off.
"I didn't know if it was friendly or not so I picked up my dog and it bit her on the leg first.
"Then it bit my leg two or three times. I told the owner to call the police.
"He just said his dog wouldn't have bitten if I hadn't picked up my dog, but I didn't want her being shredded to pieces.
"Everything just happened so fast, I think it was just the adrenaline and shock that kept me going."
Sam managed to stumble home despite his leg bleeding heavily.
He was treated by paramedics at his home in Heywood, who also took a look at the dog, and was then taken to nearby Fairfield hospital.
His partner, Adam Robb, 28, said Sam and Beth were both 'extremely shaken up'.

He said: "Beth has become quite subdued, she has to go back to the vets for follow up treatment.
"There was a lot of blood coming from the wounds in Sam's leg."
Sam added: "I don't want anyone else to go through what I did. It could have been a child.
"There are lots of dog walkers on the field usually, and it could have been a lot worse. If I’d have been pulled to the floor it could've had my face."
A Greater Manchester Police spokesman said: "A man was walking his dog near Mutual Mills. Another dog ran over to them and the man then picked up his dog.
"The other dog then bit him in the leg and another person approached. The victim then called the police [after the Pit Bull owner fled with his dog]."
