18．When the dog named Judy spotted the first sheep in her life，she did what comes naturally．The four-year-old dog set off racing after the sheep across several fields and，being a city animal，lost both her sheep and her sense of direction．Then she ran along the edge of a cliff and fell 100 feet，bouncing off a rock into the sea．
Her owner Mike Holden panicked and called the coastguard of Cornwall，who turned up in seconds．Six volunteers slid down the cliff with the help of a rope but gave up all hope of finding her alive after a 90minute search．
Three days later，a hurricane hit the coast near Cornwall．Mr．Holden returned home from his holiday upset and convinced his pet was dead．He comforted himself with the thought she had died in the most beautiful part of the country．
For the next two weeks，the Holdens were heartbroken．Then，one day，the phone rang and Steve Tregear，the coastguard of Cornwall，asked Holden if he would like his dog back．
A birdwatcher，armed with a telescope，found the pet sitting desperately on a rock．While he sounded the alarm，a student from Leeds climbed down the cliff to collect Judy．
The dog had initially been knocked unconscious but had survived by drinking water from a fresh stream at the base of the cliff．She may have fed on the body of a sheep which had also fallen over the edge．"The dog was very thin and hungry，"Steve Tregear said．"It was a very lucky dog．She survived because of a plentiful supply of fresh water，"he added．
It was，as Mr．Holden admitted，"a minor miracle"．
