just in relation to cockers i have had them for the last ten years.three things i have found with them.1. they get very cute with experince.eg.a cocker will not go into cover if there is no game there.a spaniel hunts just to please you and will go into empty cover.2. you will always shoot more with a cocker because he is more thorough and has a better nose.always hunt on ground where there is game,they switch off very easily.and they dont come into their own till their 3 years old.there is an old saying about cockers.when you have a good one you have a great dog.it is so true.
