we have a whippet x greyhound bitch,2 years old 50 lb in weight ,she loves to chase and does some rabbiting on our fields. we would like to try her at racing and obviously as we are new to all this need to know how to get started and who to contact. we also would like to know where are the local racing tracks. We live near Barnard Castle in Co. Durham. We would be grateful for any help and advice
