• I had to persuade a dog to swallow a pill. I twittered for advice and I got suggestion after suggestion. Most of them didn't work. 'Put the pill in the sausage.' No - that doesn't work. 'Cheese.' No. Then someone said: 'You wrap it in butter and it will slide down.' I tried it and it worked! And I'd learnt how to give a pill to a dog through the magic of Twitter.
