hi rob , i would get your recall 100% in the day first . Then for the first few outings on lamp ,dont worry about being to tactical . As soon as your dog catches or misses ,recall - even if it means shouting,whistle or however you recall during the day . back on the lead ,praise , move on . it will soon get the hang of it . After a few outings it will know its job, and will return without recall . -robo
