it does sound a handy cross if the pat came from proven lines ,it could a good alrounder . My wife used to have a whippetx jrt which was good at the useal quarry as been sad the pat seems to be the choice terrier at the moment, so who know the patx greyhound could be the next big thing.
I think you would need a small greyhound bitch or build a platform the stud or stand the bitch in a hole so the stud would be able to cover her.
