(a) Except as otherwise provided in this chapter, all animals, including dogs and cats, that are abandoned, found at large, taken into custody by the animal services director, or otherwise found to be in violation of Division 416 of this code, will be taken up and impounded, and are subject to destruction by humane injection.

(b) A person who finds a stray domestic animal at large, whose owner is unknown or cannot be immediately contacted, may temporarily retain and care for that animal. Within eight hours after finding the animal, or as soon as the animal services department opens for business if the department is closed when the animal is found, the person retaining the animal must: (A) notify the animal services department that they have the animal in their possession; (B) provide to the department a description and photograph of the animal; (C) have the animal scanned for a microchip; and (D) state their name, where the animal was found, and where the animal will be held until its owner is located.

(c) The finder of an at-large animal is obligated to provide the animal humane treatment.

(d) When the owner of a found animal is located, the person holding the animal shall either immediately surrender the animal to the animal services department for impoundment or return the animal to the owner. The finder shall not charge the owner for compensation except to recover a reasonable charge for saving and taking care of the animal as permitted by Civil Code Section 2080. If no owner is located within 30 days, or the owner does not claim the animal within the time provided in Section 416-8.006, then the finder may claim ownership of the animal or provide the animal for adoption by a new owner.

(a) Unlicensed Dogs. Any unlicensed, unaltered dog impounded under Section 416-8.002 must be spayed or neutered prior to its release from the animal services department unless the dog is exempted from the license requirements under subsection (a) of Section 416-6.004 or has a medical exemption under subsection (d) of this section.

(d) Medical Exemption. The animal services department will release intact any unaltered dog impounded under Section 416-8.002 that cannot be spayed or neutered due to a medical condition that is confirmed by a veterinarian licensed to practice veterinary medicine in the state of California. Before releasing the dog, the animal services department will issue the dog's owner a written notice requiring the owner to spay or neuter the dog and provide proof of correction within two months of the date of the notice. The animal services department may extend the two-month correction period if, based on the opinion of a veterinarian licensed to practice veterinary medicine in the state of California, the medical condition continues to prevent the dog from being spayed or neutered. The dog's owner shall be responsible for paying the costs of any medical examinations rendered pursuant to this section.
