Why are Beagles not reliable off-leash dogs?

Answer

That nose dictates their world, making commands like 'come' irrelevant when a scent trail appears.

Their ancient tracking instincts mean that when they catch a compelling scent, their focus shifts entirely to the trail, overriding any recall command given by the owner, necessitating constant confinement via leash or fence.
