I suppose because I do no think I have a strong enough character.....for them. Staffords are a relatively easy breed I find maybe I am used to them hence find them so. I have a childhood memory of a lovely retired man "George" who had the most beautiful GSD's Turk and then Elsa. Turk a beautiful short coat and Elsa along haired bitch........I used to walk with him and learnt a lot from holding the lead upwards. And I recall them being the most beautiful of dogs with their character, behaviour.
