Don't know how to remove the post for them but I guess if your friend sends an email to admin they will remove it for them. It may be that your friends dog had not got enough going for him for people to be interested. Was the dog health tested for the problems know within the breed and had it been winning well in the show ring if the answer to either is no then your friend knows how to improve the chances of someone making enquires regards using their dog, it is also a problem if the dog is over say 18 months and has not been used and his close relatives have not been know to product good pups who are of breed standard.
