I wouldnt write a halfcross off Harrial if I was you mate. If you get the right dog they are brilliant, steady but clever and very hardy. Get one that hasnt got the shy gene and with good feet and you can have years of fun, and with far less injuries than a 3/4 Greyhound type. They tend to bounce off things rather than break like a Greyhoundy type. A half x can be lurcher to lurcher for many generations as long as it keeps the type, athletic but strong with drive. Youll get better hunting with a half cross aswell. Good luck anyway.
