Riverside County supervisors have unanimously passed a rule requiring pit bulls to get spayed or neutered.

Terry Armenta lives in the county, owns a pit bull and says the rule is unfair.

"It's just like human beings," Armenta says.

"Do you eradicate an entire human race for the actions of a few? No."

Riverside County Animal Services says the rule would actually save pit bulls from ending up in shelters and ultimately being put down.

The rule goes into effect in a month.

It was proposed following several pit bull attacks in the area, including one that killed an elderly woman in Hemet in February.

Police dogs and breeders are among those that will be exempt.
