Here’s the best way to demonstrate why climbing on a dry stone wall can be hazardous to your health. This wall in my garden had been showing an alarming bulge for the last few months and yesterday, this was the outcome.

This was not caused by an adult or even a child climbing on the wall but my Welsh collie Rhosyn, who weighs under 15kg, jumping on to the wall. Fortunately she was not hurt but we were quite shaken!

So, when you realise that you have to walk the length of a field to get to a gate because of a dry stone wall, DON’T be tempted to climb over!
