In much of Europe, temperatures are up to 12 degrees above normal for the time of year (the height of summer). In Germany, it's no different. The forecast high in Frankfurt today is 37 degrees. It's very energy-sapping. Many homes - not to mention hotels - are without air conditioning. These dogs have got the right idea.
It reminds me of the best summer I remember from my days as a youngster in Britain. The grass was always brown and there were weeks of sunshine during the school holidays.
