I've got a bulldog he's been out with me a couple of times, I only started up about a month ago so don't have a lot of of work at the moment, don't think I could cope with having him with me all day every day would slow me down too much as he's far too stubborn and lazy. A boxer dog would be a lot easier I'd imagine, lovely dogs an very intelligent. It's true what they say it's a mans best friend.
