I was also thinking about a whistle recall as a new thing to introduce, but again takes time.
However, I do think once they have been trained to do something on a particular path they start to do it automatically at the same place each time.
Teaching loose lead walking can be so hard yet I get to a certain road and Maddie does it perfectly. I'm sure that's because I managed to get it right the first time!
Absolutely agree - there are stretches of road where Humphrey just automatically falls in to heel, with or without lead because they were places where we practised a lot, other bits he‘s been allowed to pull and no amount of work will get him to break the habit there. If I can give one tip, which I wish I had heeded, (
) its to be consistant, decide on a good method of teaching lose lead walking and try to stick to it, even if you think it‘s not working, keep at it and be strict with yourself and your dog. Your dog is still young, the time you put into training now will be rewarded later, this is the time where habits, both good and bad! it IS a slow process, cockers are renowned for pulling and if you look through some of the older threads on here, you‘ll find that we‘ve (nearly) all had the problem. You‘ll get there! Best of Luck!
