Food & Agr. Code, § 31108

(a) (1) The required holding period for a stray dog impounded pursuant to this division shall be six business days, not including the day of impoundment, except as follows:

(A) If the public or private shelter has made the dog available for owner redemption on one weekday evening until at least 7 p.m. or one weekend day, the holding period shall be four business days, not including the day of impoundment.

(B) If the public or private shelter has fewer than three full-time employees or is not open during all regular weekday business hours, and if it has established a procedure to enable owners to reclaim their dogs by appointment at a mutually agreeable time when the public or private shelter would otherwise be closed, the holding period shall be four business days, not including the day of impoundment.

(2) Except as provided in Section 17006, stray dogs shall be held for owner redemption during the first three days of the holding period, not including the day of impoundment, and shall be available for owner redemption or adoption for the remainder of the holding period.

(b) (1) Except as provided in Section 17006, a stray dog that is impounded pursuant to this division shall, before the euthanasia of that animal, be released to a nonprofit, as defined in Section 501(c)(3) of the Internal Revenue Code, animal rescue, or adoption organization if requested by the organization before the scheduled euthanasia of that animal. The public or private shelter may enter into cooperative agreements with an animal rescue or adoption organization. In addition to a required spay or neuter deposit, the public or private shelter, at its discretion, may assess a fee, not to exceed the standard adoption fee, for animals adopted or released.

(c) During the holding period required by this section and before the adoption or euthanasia of a dog impounded pursuant to this division, a public or private shelter shall scan the dog for a microchip that identifies the owner of that dog and shall make reasonable efforts to contact the owner and notify the owner that the owner’s dog is impounded and is available for redemption.

(d) As used in this division, a “business day” includes any day that a public or private shelter is open to the public for at least four hours, excluding state holidays.
