I agree with who say :"There are working owners, not working dogs"
I own two good dogs, with well balance-self confident character, but I really have small time to train them...they
maybe could be really "working dog" but till now they make only some easy exams.
Obviously with some very shy csw you can't do nothing, apart running 100km...so running for km and km it's not a prove of typical csw character, i think.
