Summary
In the City of Waterloo, Iowa, a dog or cat off its owner's property is legally "at large" unless it is on a leash, rope, cord or chain at least ten feet long, safely restrained in a vehicle, or inside the fenced boundaries of a designated dog park with its owner present. Letting a dog or cat run at large is a municipal infraction enforced by Animal Control.
An animal is at large if it is found within the city off the premises of its owner or caretaker, however, an animal will not be deemed at large if: ... In addition, a dog or cat, properly licensed as required by article A of this chapter, will not be deemed at large if: a) it is restrained by a rope, leash, cord, chain, or restraining device not less than ten feet (10') in length, or is properly restrained within a motor vehicle or trailer, or b) it is within the fenced boundaries of an area designated by the city as a dog park and the owner or caretaker is present. ... A. At Large: ... It shall be unlawful for the owner or caretaker of a dog or cat to permit or allow such dog or cat to be at large. Any dog or cat found at large shall be presumed to be so with the permission of its owner or caretaker, and proof of ownership and that said dog or cat was at large shall constitute in evidence a prima facie presumption in any proceeding charging any violation of this subsection.
Full Breakdown
City Code section 5-1-15 defines "AT LARGE" for the whole animal control chapter: an animal is at large if found off its owner's or caretaker's premises, with limited exceptions such as being properly housed in a licensed kennel or under the control of authorized personnel. For a licensed dog or cat specifically, the code adds that it will not be deemed at large if it "is restrained by a rope, leash, cord, chain, or restraining device not less than ten feet (10') in length," is properly restrained inside a vehicle or trailer, or is within the fenced boundaries of a city-designated dog park while its owner or caretaker is present.
Building on that definition, section 5-1A-6A makes it unlawful for an owner or caretaker to "permit or allow such dog or cat to be at large," and treats any dog or cat found at large as presumptively at large with its owner's permission, a presumption that shifts the burden onto the owner once animal control documents ownership and the at-large condition.
Violations & Fines
Letting a dog or cat run at large without the required leash, restraint or dog-park confinement is a municipal infraction under section 5-1A-6A, enforced by Animal Control and the Waterloo Police Department. Where the loose dog's circumstances match the aggravated situations described in section 5-1B-9, the violation instead becomes a misdemeanor, and repeat offenses after a first violation are treated as subsequent offenses for penalty purposes.
