Thanks jasper for all the info,
and i appreciate you taking time out to answer my question in depth,
iv been doing a lot of reading up and chating to a few people, and it all come's together with what your saying about P/R gosses .
my plan is to train up my cocker first, then taken on a gos, and work them together...
thanks again jasper and i will keep you in mind when the time is right for me to take on a gos.
