I solve the problem using a callback and a title inside the tooltip:

options: {
        tooltips: {
            callbacks: {
                label: function (tooltipItem, data) {
                    var dataset = data.datasets[tooltipItem.datasetIndex];
                    var total = dataset.data.reduce(function (previousValue, currentValue, currentIndex, array) {
                        return previousValue + currentValue;
                    });
                    var currentValue = dataset.data[tooltipItem.index];
                    var percentage = Math.floor(((currentValue / total) * 100) + 0.5);
                    return percentage + "%";
                },                    
                title: function (tooltipItem, data) {
                    return data.labels[tooltipItem[0].index];
                }
            }
        }

in options definitions… 

options: {
        tooltips: {
            enabled: true,
            mode: 'single',
            callbacks: {
                label: function(tooltipItems, data) { 
                    return tooltipItems.yLabel + ' %';
                }
            }
        },
 }
