i went out on the horse this morning with the lurchers and it was certainly not -5 and believe me the ground wasn`t great if it had of been minus 5 i would not of taken horse nor dogs out but maybe i`m to soft on me dogs or maybe i want them to work fit as often as they can rather than running them partialy lame there for i know what ever there slipped on they have no injuries to niggle and cause further problems...
