Hi JillianJ,
One of the things I love about being with my hounds is that just when you start to feel confident that you know what you are doing, they will do something that makes you question what you've been doing for the past weeks, months and sometimes even years.
My comment with the attaching the leash to you and expecting your boy to follow you, is what are you hoping to achieve with this? Again I don't know the how's and where's of you doing this. But for instance I would never attach my boy to me in the house or garden as I often want to do stuff without my dog under my feet - eg cooking in the kitchen - or mowing the lawn, so to my mind it would be unfair to reward the dog for staying close to me one minute and then expect them to settle away from me in the next.
In addition, how does using the leash as a tether one moment with umbilical training help or hinder your on-leash walking - is it clear to the dog what is being required of him on each occasion?
A dear friend who is now frail and in her late 70's still walks her Irish Wolfhound and Deerhound daily, people often comment how nicely her hounds walk and when asked how she taught them, she simply replies, 'I never put a lead on them until they wanted to follow me' - therefore she and the dogs are always of the same purpose.
Whilst its not always possible to do this (I couldn't with my boy as we were apt living for his first 9 months), it is a good measure to go by, that if you dog will not accompany you without a lead why on earth do we think they will with a lead! However I now have a garden and that's what I'm working on improving now, so no lead, but making a game of him following me in the garden and getting rewarded when he is close to my left leg. In time I'll introduce a command, and then a lead! Meanwhile I will still continue with my old on leash walking protocol by stopping when he pulls - but the way he has learnt that (or I've taught it!) is that he goes to the end of his leash and then he has to stop. As its harder to reteach something, hence I'm starting over in a different way.
