Does anyone have any experience of training retired racing greyhounds? Am looking to socialise them with other dogs and to try and desensitise them from the chase of small furry things. Not asking for too much.....just want them to come to recall, wait when asked, and walk to heel on a lead. Also until then, does anyone know of a large fully secure enclosed area where I could let them off for a free run until they are trained. Thank you.
