My morning walk at top of the lane. Let the dogs out of car as normal. Walking along the road when dogs put one out of hedge back. It turned three/four times in a short space before been caught. noticed blood straight away on ted my two year old lurcher.he has worn his back toe nails straight down to the end and front ones half way !! The run was not intended obviously on tarmac just a morning walk. Cleaned him up when home.
