Valley Humane Society would be negatively impacted if Gov. Jerry Brown's proposal to repeal the 1998 Hayden Law goes through. It mandates that public shelters must hold animals for four to six days before euthanizing. If the law is repealed, animals will have 72 hours. California Department of Public Health records show that 576,097 dogs and cats were euthanized in county shelters in 1997. The number dropped to 327,991 after the law went into effect.
