Take no notice of Gooey, aka mC HULL, mate.
If your dog ain't got saluki in it and/or fluffy ears, he's adamant that your dog can't catch a hare, and will call you a liar, he's done it to me on a few occasions lol.
I've owned whippets and whippet/greys, that caught plenty of hares, lamping and daytime.
That white bitch you have looks a belter.
Wait for Gooey's reply to this, something along the lines of 1976, I've never owned a dog, especially a whippet, that could catch a daytime hare, etc etc, can't help himself!! Lol
