10.08.130 – Permit to keep dogs and cats.:
(a) No person shall keep more than three dogs over four months of age, nor more than three cats over four months of age, at any one place, or on any premises, or in any one residence located within the jurisdiction of the county. Subject to the exceptions provided in this chapter, no person shall harbor any cat or dog unless spayed or neutered. For purposes of this section and chapter, “harbor” means legal ownership, or the providing of regular care or shelter, protection, refuge or nourishment, or medical treatment; provided however that the term shall not include the providing of nourishment to a stray or feral cat or dog. This spay and neuter restriction shall not apply to dogs or cats kept pursuant to a breeder/show permit, or kept on the premises of a business for the sale, breeding, medical treatment or caring for hire of animals which is in compliance with all applicable permits, and other requirements of this code, or dogs and cats kept at an animal shelter or under the care and custody of the animal control officer or a rescue organization.
(b) This provision shall not apply to dogs in use by any federal, state, or local law enforcement agency or guide dogs specifically trained and used to guide a person who is blind or a person with a disability.
(c) The spay/neuter requirement set forth in Section 10.08.130(a) shall not apply if a licensed veterinarian certifies in writing that a specific dog or cat is temporarily or permanently medically unfit to undergo the required spay or neuter procedure because of a physical condition that would be substantially aggravated by such procedure or would likely cause the animal’s death. If temporary, the certificate shall indicate the period of time anticipated that the unsuitability will last. For an exemption to apply beyond that period, a new certificate must be obtained from a veterinarian. The certification may be transmitted electronically.
(d) The spay/neuter requirement set forth in Section 10.08.130(a) shall not apply to animals harbored by a pound, shelter, humane society or similar organization, whether public or private, the principal purpose of which is securing the adoption of dogs or cats provided that such organization requires the spaying or neutering of all dogs and cats prior to placement of such animal for adoption by such organization.
(e) Kittens and puppies born to cats and dogs not spayed or neutered in violation of this chapter shall be forfeited and given to the care of a local shelter for adoption.
