William Woods says he was attacked while walking along Arroyo Boulevard. He says it was all over his two dogs, Woof and Kibble.
"My wife is terrified," Woods told Eyewitness News. "I'm kind of worried that if this goes anywhere, he could come back and get me."
The incident happened Saturday. He says a person walking with two girls saw his dogs were off leash and didn't approve.
"This guy starts yelling at me about how you gotta have your dog on a leash, it's illegal not to, and I said thank you," Wood recounted. "I didn't want to get into anything.
"Frankly, some f-bombs were tossed... Then he charged me. So he picked me up and threw me, and I picked myself up and I thought I've been wronged here."
Woods says he got up to take pictures of the man, and he was attacked a second time.
"It was a violent enough approach that my glasses - I'm blind without them - were about 40 feet away," he said.
Photos of Woods' injuries show he was bloodied on his leg and arm. He immediately reported it to police.
Pasadena city spokesperson Lisa Derderian said Woods having his dogs off leash is illegal, but it shouldn't have led to an attack.
Woods said he understands it is illegal to have the dogs off leash in that area.
"If I ever get a ticket, I will pay it," he said.
Officials say Pasadena police searched for the suspect. As of now, police don't know who he is.
"We encourage people to please call the Pasadena Police Department with any information because this is an ongoing investigation and any additional leads will be helpful to us," Derderian said.
Woods says all he can do is wait to see if police find the suspect.
