Many years back I was in N.Wales supervising D.of E. Expeditionists for gold level award and was staying at a hostel where a lovely collie lived.
In those days the hostel was only open at cetain times and as I got back early I was sitting outside in the sun. Along comes this collie and sits beside me and look at me strangely. I thought it wants me to play with it so I found a stick and threw it. Nothing, it sat and lokked at me. I got up got the stick and threw it again. Still nothing. Several more tries and the dog tilted its head as it looked at me. Then a cat appeared the dog shot away after it. Trouble I thought, but no the dog and cat sat together for a few moments as friends as if talking. Then the dog returned to sit with me. I tried once more with the stick nothing. I went to get the stick to try again and I was sure the dog looked at the cat and was saying "look what I have trained him to do".
When looking on the dogs collar I noticed that it was a SARDA, (Search And Rescue Dog Assoc) and thought that explains it. These dogs are the cleverest and best trained you can get.
