It happened in Arvada at Parkview Village Apartments.
Police say it was an off-leash American Pit Bull Terrier that caused the injuries to the other dog.
"I don't have kids, so this is my baby," Bernadette Sena said.
Sena's 11-year-old dog Binga was on a leash Saturday as the two descended the steps toward the entrance of the apartment building.
Sena says Binga ran into the off-leash American Pit Bull Terrier, who bit Binga's head and wouldn't let go.
"We had blood all over us," Sena said.
Soon, a crowd had gathered. She and other neighbors tried to get the dog off of Binga. Finally, they succeeded.
"We didn't even know if she was alive or not," Sena said.
Now, Sena wants all dog owners out there to be careful, and aware.
"If you're going to have a dog, be responsible. Keep them on a leash and chain," Sena said.
She is thankful that, despite her dog's obvious wounds, Binga is alive.
"She's okay, she's going to be okay, thank God," Sena said.
Police say they know who the owner of the bull terrier is, but they haven't been able to contact him at home or by phone.
As for the dog, it was last at the Arvada Police station.
We're told it would be taken to Foothills Animal Shelter and then quarantined for 10 days. Police say there had been no prior complaints against the American Pit Bull Terrier.
