I'm sorry that your dog is sometimes reactive, and you can count on a threshold, but I cannot. Your dog isn't my dog, and a ecollar would most likely be the most effective for my dog, however I have decided to try one of the ways listed above instead. Even if o have his attention BEFORE I will not have it when he hears or sees something.
It is unfortunately obvious that you have no idea what a dog's "Threshhold" is or what it means in training a dog. So I am sure that it is best for you "not to count on one!".
And please be assured that neither me or my dog hass any need for your sympathy about him being sometimes reactive to another dog that challenges him - we can and do deal with it very well!
You certainly do know best what is best for your dog - why else would you choose to use another way to train your dog other than the method that "would most likely be the most effective for my dog"?
Thank goodness that you do realize that "your dog is not my dog".
This would seem to indicate that you do know that all dogs are different, right?
BTW, just to remind you, the idea of training (and then proofing a dogs training), is to insure behavior when they are distracted. I.E. you need to train your dog to have "FOCUS" in the event that they do get interested in something.
It is sad that you seem to accept the following:
" Even if o have his attention BEFORE I will not have it when he hears or sees something".
Hang in there. Maybe you can learn to pay attention to what other more experienced trasiners have to tell you and maybe together you can actually "Train" to focus on you and not on the other things around him/her?
Good luck with your dog!
