Building on Ryan's code, you can shorten the object check and you should also NOT extend functions so you don't override object pointers.

var extendDeep = function extendDeep(dst) {
    angular.forEach(arguments, function(obj) {
        if (obj !== dst) {
            angular.forEach(obj, function(value, key) {
                if (dst[key] && angular.isObject(dst[key])) {
                    extendDeep(dst[key], value);
                } else if(!angular.isFunction(dst[key])) {
                    dst[key] = value;
                }
            });
        }
    });
    return dst;
};
