i had very interesting chat today on my dog walk, got my 2 dogs and met this bloke and little lad with 2 collie xs , not lurchers just farm type working dogs , he liked my dogs, i told him they were of similar temp at home quite and sensitive , but the big dog Buck 1x gsd x grey , had very different mind set when hunting he was more full on than Bryn the 1 x collie x grey . he said that didn't surprise him , he said collies will do most things for there owners, there are very clever and appear to do as there told, but in truth there calling the shots, they only do what they want .
