A spin off from the "kick the dog" thread.
1. For what behaviors would you use leash corrections as a training method to solve a problem or teach a dog?
2. And for how long would you continue before you found it ineffective?
For me I used leash corrections for Jumping on guests and chasing my cat, both of which took only a couple of weeks of training. I don't know for sure how long I would have gone but it wouldn't have been to long before I found it ineffective. I have found that punishment has it's place for me and my dog, but that place is limited and so is the punishment.
It doesn't have to be leash corrections any aversive method you used would be interesting.
