Border Collie

Steady miles suit a Border Collie better than frantic play. The breed can be affected by Border Collie Collapse, an episode of wobbling and disorientation linked to intense, highly exciting exercise; some affected dogs cannot handle a ball-throwing session yet can run for several miles without symptoms. A rhythmic trail run is the kind of outlet that suits it. Light, agile and quick to learn cues such as "wait" and "with me", it is an easy dog to keep under control on shared paths. It needs a job for its brain too, or it will invent one.
