Just sneaking a quickie in here. I've just watched a programme on BBC iplayer, about dog walkers on Hampstead Heath, and it was lovely. The people interviewed had some very moving stories to tell about their circumstances and why they love their dogs. It showed how the love of a dog can be a great healer, and when things get tough it's the dog which helps them carry on. Have a look if you haven't already seen it. Maybe our overseas readers might not be able to open the link, sorry.
