Rip blue.. I feel for you mate and know the feeling and even last night nearly had a similar situation myself when first x bitch pup pulled loose from lead on a big beastie and lost the bitch for a few hours. Still had lead on and I was sure she was dead but found both parties in a heap.. So was lucky this time but it's a horrible feeling and I wouldn't wish it on my worst enemy. Chin up mate. Atb Keith
