im only a novice conpaired to most but all i say is if you dont know how to condition a dog then why own one ? i just get my bitch fat then run her on the lamp , let her work the fat of , then you can start to see the dog getting fitter everytime you go out , my bitch kills daytime hares and on the lamp (pre ban) and shes 3/4 grey 1/8 bull 1/8 saluki which id call a lamping dog
