Individual dogs offered for sale in a pet shop or licensed commercial animal establishment, dogs in a veterinary facility or research facility, or dogs in a grooming or boarding facility not owned by the proprietor of the facility, are exempt from the licensing requirement while kept in the facility. It is an affirmative defense that the owner temporarily resides or travels in the city for a period not exceeding thirty (30) days and does not, therefore, need to license the animal. (Ord. 2667 § 2, 2001)
