Humphrey loves sniffing and retrieving so we take a few home made dummies with us on walks and incorporate various games en route, - I‘ll drop them while walking and them send him back to search and bring them to me, sometimes one, sometimes 3 together, sometimes I hide them, sometimes I drop them while he‘s walking to heel so he has to ignore them until I send him back to search. I never throw dummies or balls for him to chase, he has to sit while I throw and is only allowed to retrieve them on command. All these exercises are to train self control and discipline and discourage chasing wild life and, up until now (although I never say never) we‘ve had no problem with him doing a runner despite living in the back of beyond and being surrounded by deer, boar etc etc. I don‘t entertain him the whole time, he‘s allowed to amble along aswell and sniff and do his thing but I try to include a few sits, down, stays , heels, etc on all walks. He doesn‘t work but we‘ve joined a dog club and do fun activities which involve basic obedience and give him an opportunity to socialize. On the whole, he‘s pretty well balanced, does have his cocker moments but then, he is a cocker after all! 😉
