§ 6-1.801 PURPOSE; DEFINITIONS.

(A) Purpose. The purpose of this article is to reduce the risk of serious attacks or bites by dogs or other animals. This article sets forth the procedures for finding an animal potentially dangerous or vicious and subject the animal to appropriate controls and enforcement actions. (See Cal. Health and Safety Code §§ 31601 et seq.; Cal. Food and Agric. Code §§ 31601 through 31683.)

(B) Definitions. For the purpose of this article the following definitions shall apply unless the context clearly indicates or requires a different meaning.

POTENTIALLY DANGEROUS DOG OR ANIMAL. Any of the following, as determined by the city:

(a) A dog or other animal which, when unprovoked, on two separate occasions within the prior 36-month period, engages in any behavior that requires a defensive action by a person or another animal to prevent bodily injury when the person and the dog are: off the property of the dog's owner; or on the property of the dog's owner by invitation or with implied permission. (See Cal. Food and Agric. Code § 31602);

(b) A dog or animal which, when unprovoked, bites a person causing a less severe injury than as defined here as a SEVERE INJURY (Cal. Food and Agric. Code §§ 31602 and 31064); or

(c) A dog or animal which, when unprovoked, has bitten, inflicted injury or otherwise caused injury attacking a domestic animal. (See Cal. Food and Agric. Code § 31602.)

SECURE ENCLOSURE. A kennel, pen or structure with secure sides and a secure, attached top. The kennel or pen shall be constructed in a manner so that it cannot be broken down by any action of the confined animal. All structures used for confinement of a vicious animal must be locked with a key or combination lock of sufficient strength to ensure confinement of the animal. The structures must be erected on a secure bottom or floor constructed of concrete or other material sufficient to prevent the animal from digging free. A vicious animal enclosed in a house, apartment, building or similar structure is allowed only where the windows and doors of the structure are secured to prevent the animal from exiting without the assistance of the owner or other person in control. (See also Cal. Food and Ag. Code § 31605.)

SEVERE INJURY. A physical injury to a human being that results in muscle tears or disfiguring lacerations or requires multiple sutures or corrective or cosmetic surgery. (See Cal. Food and Agric. Code § 31604.)

VICIOUS DOG OR ANIMAL. Any of the following, as determined by the city:

(a) A dog or animal seized under Cal. Penal Code § 599aa and upon the sustaining of a conviction of the owner under Cal. Penal Code § 597.5;

(b) A dog or animal which, when unprovoked, in an aggressive manner inflicts severe injury on or kills a person or a domestic animal;

(c) A dog or animal previously determined to be and currently listed as a potentially dangerous dog or animal which, after its owner has been notified of this determination: continues the behavior described as a potentially dangerous dog or animal; or is not kept indoors or secured on the owner's property. Here, SECURED means contained within a fence or structure suitable to prevent the entry of young children and to confine a potentially dangerous or vicious dog or animal, designed to prevent the animal from escaping. (See Food and Agric. Code §§ 31603, 31641, 31642 or 31643.)

(C) Other definitions in § 6-1.102 also apply unless the context indicates or requires a different meaning.

§ 6-1.802 SEIZURE AND IMPOUNDMENT.

If upon investigation the Animal Control Supervisor or law enforcement officer determines that probable cause exists to believe a dog or animal poses an immediate threat to public safety, then the Animal Control Supervisor or law enforcement officer may seize and impound the animal pending the opportunity for hearing under this section. (See Cal. Food and Agric. Code § 31625.) The animal's owner is liable to the city for the fees and costs of keeping the animal if it is determined to be potentially dangerous or vicious. At the Supervisor's discretion, the animal may be quarantined on the owner's property in an approved enclosure. (See Cal. Food and Agric. Code § 31605 regarding enclosure. See also definitions at § 6-1.801(B).) (See § 6-1.705(A) regarding fees and costs.)

§ 6-1.803 DETERMINATION OF POTENTIALLY DANGEROUS OR VICIOUS DOG OR ANIMAL.

No dog or animal may be declared potentially dangerous or vicious if:

(1) The injury or damage was sustained by a person who, at the time, was committing a willful trespass or other tort upon the owner's premises, or was teasing, tormenting, abusing or assaulting it, or was committing or attempting to commit a crime.

(2) If it was protecting or defending a person within the immediate vicinity of the dog or animal from an unjustified attack or assault.

(3) Any other exception applies under Cal. Food and Agric. Code § 31626.

(B) Notice to owner; appeal.

(1) The Animal Control Supervisor or law enforcement officer shall attempt to notify the animal owner of the animal in writing of the impoundment and of the determination that the dog or animal is determined to be potentially dangerous or vicious. The notification shall include any requirements to be imposed upon the restraint and enclosure of the animal, or if the animal is proposed to be euthanized. The city may also notify the property owner, police department, fire department, post office and any utility companies of the determination and any requirements.

(2) The notice shall also contain information that the officer's determination may be appealed to the Board of Administrative Appeals, within the time specified in Municipal Code Title 1, Chapter 4, Appeals. The procedures and appeal period shall comply with Cal. Food and Agric. Code §§ 31621 through 31625.

(3) The Board of Administrative Appeals may decide all issues for or against the owner of the animal, even if the owner does not appear at the hearing. (See Cal. Food and Agric. Code § 31623.)

(4) The decision of the Board of Administrative Appeals may be appealed to the superior court under Cal. Food and Agric. Code § 31622.

(C) Permit. If not euthanized, an animal designated potentially dangerous or vicious may only be owned, kept or maintained upon issuance of a potentially dangerous or vicious animal permit. The Animal Control Supervisor shall impose conditions upon the ownership and custody of the dog or animal that protect the public health, safety and welfare. (See § 6-1.804.) The animal owner shall notify the Animal Control Supervisor within two working days if the animal dies or is sold, transferred or permanently removed from the city. (See Food and Agric. Code § 31643.) The owner is responsible for notifying the subsequent owner of the potentially dangerous or vicious designation.

If a determination is made that the owner of the potentially dangerous or vicious animal has violated the conditions of a potentially dangerous or vicious dog permit, the permit is immediately revoked and the animal may be euthanized at the discretion of Animal Control.
