The keeper shall display signs in such form as required by the city and borough on the keeper’s premises warning that there is a potentially dangerous or dangerous dog on the premises. One sign must be visible from any public right-of-way abutting the premises. A sign must also be posted on the enclosure for the animal. If the animal is transported in a vehicle, a sign must be clearly visible that the animal transported is potentially dangerous or dangerous. (Ord. 02-1656 § 4(A), 2002; S.G.C. § 8.04.087.)
