I totally agree, you get through it by wondering why they are so upset?? We should all have the good of our dogs at heart and be working towards a better future. Sadly not everyone is upfront about things in their lines and they don't want to look in case they find something.
I always think that as long as my conscience is clear then that's all I can hope for, husband always telling me I can't take on the worries of the world :(
