Deworming / Tapeworm Treatment Rules
Wisconsin does not require tapeworm treatment for dog entry.
Routine deworming is recommended due to forests, farms, lakeside wildlife, and rural exposure, but it is not legally required.
Restricted Breeds at Entry
Wisconsin has no statewide breed restrictions.
However, some municipalities — including Milwaukee suburbs and smaller towns — may enforce dangerous-dog ordinances. Always verify local city or county rules.
Public Transport & Transit Rules
Service Dogs are allowed on all public transit systems, including Milwaukee County Transit System, Madison Metro, and regional bus networks.
ESAs and pets may be restricted unless in carriers or depending on transit-agency policies.
