would say a 3/4 bred may do job local feilds for a run or 2 , but not on good land , will not have the lungs to stay 3 runs or more , get yourself a coursing bred saluki / saluki hybrid , bred for the job , , not saying collie x's cant run a good hare because they can , but you get a dog suited to what you run most , i dont lamp , therfore dont have a lamping dog , i have salukis in get my drift
the collie based dog is a good ALL ROUND dog IMO good for bit mooching during day and can make cracking lamping dogs , cant find many faults with them , but not many would take a 1st cross coll
