Thats an harsh lesson mucker,money time and effort that would have bourne fruit with a pup from genuine grafters,bred from grafters.Id never own a pup unless i actually witnessed at least one of the parents tested,not always possible,but easier to walk away from a breeder thats unwilling to show a dog at work,than it is to part with brass on a chancer.
Yes mate hard lesson learnt!!!! Alot of time and money wasted. Put me off this cross for life and would never go down the deerhound/greyhound route again. Showed me up many a times that dog.
