Most common mistake that I've seen over the years imo is a lot of people want to dig their dog out straight away, as soon as they hear them yap in a spot they have the shovel out . Sit back keep calm and have a cuppa then check out the state of play . Years ago we never had the pleasure of pin pointing the dog before on top , we had to search for the dog after a period of time . We still then after finding the dog had a cuppa and then start to dig to the dog . Makes for a better dog I'd say .
