Basics must be done before anything further.
1. Have your cocker sit when you stop walking (on the whistle if you intend to do trials)
2. If you achieve #1 it will sit at distance when whistled.
3. Stay when you say so and you must be able to walk at least 20 yards without it breaking.
4. Come to you when you bid it to.
5. And this is the most important one, heel when walking without constant reminder.
Without these working all other training activities will suffer measureably.
