The owner of the small dog created a GoFundMe titled 'Justice for Cheese.'
The GoFundMe page states that after five days in the ICU, Cheese passed away.
"Cheese was our family. He was sweet, gentle, loving - pure joy in the shape of a little dog. Now the house is quiet," the page says.
Fremont resident Nahim Fedai goes to the park at least four days a week.
"So sad, that's very sad, seriously, what if that happened to my dog, you know, you got to feel the moment, whoever is going through this," Fedai said.

"You know, when I see a bigger dog every time I see I just carry him because you never know," Fedai said.
Residents who come to Central Park tell ABC7 News it's very safe but there have been close calls in the past.
Alen Fong said in July, a medium-sized dog was off leash and made a beeline for his dog, a moment he said was terrifying.
"I was like, holy crap so I picked up my dog, kicking it away - the owner realizes what happened and calls it back," Fong said.
Alexis Gomez is a dog trainer based in Contra Costa County. She owns Seeonee Super Dogs. She says in this case - it's important the owner comes forward.
"Ultimately, you chose to take your dog off leash, you chose to make the wrong decision, whether you knew your dog was aggressive or not, whether you had a feeling or not," Gomez said. "It doesn't matter if you believe you have the best well-behaved dog in the world, your dog ultimately caused this situation and it's what's right to do."
