You can do this with a valueFormatter:

new Dygraph(
    document.getElementById("graph"),
    "X,Y\n" +
    "1,0\n" +
    "2,2\n" +
    "3,8\n",
    {
      legend: 'always',
      axes: {
        y: {
          valueFormatter: function(v) {
            return v + ' mph';  // controls formatting in the legend/mouseover
          },
          axisLabelFormatter: function(v) {
            return v + ' mph';  // controls formatting of the y-axis labels
          }
        }
      }
    });
