Thank you makes perfect sense and tha answer i was looking for,
Basically my boys are as different as night and day, Dalton has the drive, always wanting to do something, what we doing newxt mum attitude, left to his own devices he is a horror, loves doing jobs, carrying his treats back from the petshop in his back pack, We are working on his prey drive right now, and its working, just basically ragging him around then training so he is always busy apart from his puppy time ofcourse, i cant explain him properly really, but he loves training retrieval, everything you can think of, and after the odd challenging day he is doing so well, walks watching me all the time, so focused. He is my first GSD.
Now Kane is another story, has little concentration, and is very happy with playing, a cuddle, food and a walk. he would much rather chase butterflies in the field

, you call him he comes bless has a treat then gets ingrossed in some ants in the grass haha.
Anyway, just wanted to make sure my thinking was correct in assuming Kane is much more of a pet bless, and has no desire to work.
Dalton loves any form of training, activity, apart from puppy time and his naps
Iknow little about breeding lines, but just wanted to make sure my thinking was correct
