SEATTLE -- Colleen Lynn was attacked by pit bull while jogging Sunday along 15th Avenue South in Seattle.

Lynn was trying to pass a woman and her pit bull on the sidewalk when Lynn said the dog lunged at her.

“And at that point, he jumped up on my chest, and knocked me down and of course that put me on the ground at sight level to him. And I put my arm in front of my face, and he grabbed on, and shook my arm in his mouth,” Lynn said.

The pit bull inflicted seven deep punctures and broke Lynn’s forearm.

“And he was holding on, to my forearm, dragging me backwards, across the sidewalk, onto the grass, and I saw his teeth in my arm,” Lynn said

Lynn was able to escape the attack and run up the street screaming.

“I wanted everybody on the block to come out of their house because at that moment, I wasn't sure if my arm was ripped off,” Lynn said.

Paramedics arrived and took Lynn to Harborview Medical Center.

Lynn will recover but is unable to work as a freelance web designer.

“For the next two months, and it will cause me great financial problems,” Lynn said.

Lynn is now campaigning for a law, requiring pit bulls to wear muzzles in public.

“It is not an expensive measure, but it may be one measure that at least ensures public safety, and really makes the owner of a pit bull understand 'I have a dangerous dog.,'” Lynn said.

The owner of the dog has surrendered him to the city who will euthanize the dog after a ten day quarantine.
