I ended up doing this a lot so I wrote a library to help address this problem : )

https://www.npmjs.com/package/reattempt-promise-function

In this example you could do something like

myApp.controller('myController', ['$scope', 'AsyncService',
function($scope, AsyncService) {
    var dogsQuery = { family: canine };
    $scope.online = true;
    $scope.getDogs = function() {
        return reattempt(AsyncService.query(dogsQuery)).then(function(dogs) {
            $scope.online = true;
            $scope.dogs = dogs;
        }).catch(function() {
            $scope.online = false;
        });
    }
}]);
