Germany has no single nationwide Leinenpflicht (leash requirement). Forest law, hunting law and dog-keeping law are each a Bundesland matter under Germany's constitution, so each of the 16 states sets its own rules, and cities or national parks can layer stricter local rules on top — a pattern that genuinely resembles Sweden's allemansrätten in the sense that the detail matters hugely, but the underlying structure is the opposite: Sweden has one national rule with local exceptions, Germany has no national rule at all.

The variation is real and specific. Lower Saxony requires a forest leash from 1 April to 15 July; Saxony-Anhalt from 1 March to 15 July. North Rhine-Westphalia requires a leash in the forest whenever a dog is off a marked path. Berlin runs a general leash requirement with off-lead areas only where specifically signed. Several states — including Bavaria, Baden-Württemberg, Hesse and Saxony, according to reporting on the state-by-state rules — have no blanket forest leash requirement at all, though Bavaria's own national parks, covered in this section's next article, set their own stricter rules regardless of the state's general position.

Breeding and nesting season (Brut- und Setzzeit, roughly spring into mid-summer depending on the state) is when rules tend to tighten even in states without a year-round requirement, and a loose trailing leash isn't a safe workaround in a bird-breeding area, since it can still disturb nesting wildlife. Given how much this varies, checking the specific state's current rule — and any posted signage at the trailhead itself — is the only reliable approach for a trip crossing state lines.
