The deerhound cross I had was 26 inch tts , if you can get one out of working type rather than show bred deerhounds ,should'nt get too tall,also had a 1st x bedlington x greyhound bitch,ran her as a coursing bitch(pre ban)she was only 23 inch tts very game little bitch,keen on the lamp aswell,but repeated short sprints used to cause her a lot of toe and stopper injuries
