never a good idea removing an inside toe, for obvious reasons, it puts much more pressure on the free flowing toe,which in no time will inevitably break, i know it's hard to accept it, but sometimes we have to, this dogs hunting days are numbered, rest it till it's ok , hopefully it will be sorted , but running on rock hard ground will cause more damage i think than running on soft ground-----atb--den
ps, keep us informed of it's progress
