Mate .Blood trailing is very easy to teach incorporated with a treat of ofal .ANY dog with an ounce of work about it will take to it well ,its the end result when they find it that seperates the purpose bred dogs from the allrounder .Lay a blood trail ,about a metre apart out of sight of the dog and then take him on it with a lead ,giving him a reward when hes reached the end .Really is that simple ,Until recently i had a lurcher that excelled at it with no training at all but sadly shes on her way out .A gun dog of any breed is ideal for this work believe me .
