OAKLAND -- Eleven scared and injured pit bulls were seized from a home in East Oakland Thursday after police found what was described as a training site for dog fighting.

Police were at a home on the 000 block of Eldridge Avenue around noon, serving a search warrant on an unrelated case. No one answered the door, but police said they heard that animals could be in the home and went to the backyard to check.

They found nine pit bulls outside, both male and female, without food or water. Inside, they found two more dogs in crates.

The dogs ranged in age from roughly 10 months to 3 years old and were "tired and terrified" and suffered from numerous wounds that were consistent with injuries sustained in fighting, said David Cronin, interim director of Oakland Animal Services.

One dog was also missing part of its ear.

Cronin said one of the dogs also bit him as he and an Oakland police officer tried to wrangle it into a collar and leash.

Treadmills that had been modified for dogs as well as weighted vests used to build muscle were found inside the home. Officers also discovered medication and syringes inside the home that were used to treat wounds, police said.

Police have begun an animal cruelty investigation, but no one has been arrested.

The dogs were taken by Oakland Animal Services and are being housed at the Oakland Animal Shelter. A veterinarian is expected to examine all eleven dogs Thursday night.
