I had two first cross Wheaten/Greyhound, excellent dogs!!! They were out of two different Greyhound bitches and the sire was pure Wheaten no bull blood in his breeding anywhere. They at the time were the only Wheaten crosses around. The first litter was doing all sorts at a very young age, the second litter took a little longer to start. I owned the sire who himself was a good dog, often think back to those days. We also put one of first crosses over a Greyhound,the pups being 1/4 Wheaten 3/4 Greyhound, they took an age to start but were worth the wait.
