Authorities in the San Francisco Bay Area say a man was arrested on suspicion of animal cruelty after police found 10 dogs without food and water living in ‘filthy’ conditions inside a trailer.

Police in Concord say one dog was discovered dead Friday and two others were so sick they had to be euthanized.

The San Francisco Chronicle reports Jeremiah Weberling could face 10 counts of cruelty. It wasn’t immediately known if he has an attorney. He remains jailed on $100,000 bail.

Weberling told responding officers the dogs belonged to him and he used the trailer where they were found as a “mobile ‘dog house,'” according to a police statement.

The statement called it an “extremely sad” case, and reminded people that animal cruelty is a serious crime.

The newspaper says it has yet to be determined if the surviving seven dogs will be available for adoption.
