That's it mate ,learning to trust is maybe an issue for some especially in company .There is definitely something in the old adage that if you smell him he's probably not in as rarely have we found one in when the entrance is stinking from a cold find ,probably pissed on last night .The exception would be hunting with hounds when many a time I've taken a deep breath at a hole ,saviouring the moment lol as charlie has bounced of the sides in his haste .
