Thanks, I have one of those, our male is a rescue, well sort of, it was a relative who passed away and the dog was 9 mths but he had already been going to dog training classes and been castrated, like I said, he is fine but I never feel totaly in controle like with the other 2, those I had since pups and they are litter mates, they are at my side on walks and thier recall is great, I also worry that the other male will lead the other 2 astray ( I posted about electric fence) as the house backs onto open fields and I can see him eyeing up an escape route but I am at home most of the time so keep an eye. I often think of getting him re homes as he is now 4, but then I love him but one day he may just need to go if he gets me into trouble!!
