Thanks so much for the help! We took a few days off of practicing them and will try again today. Yes I have been leaving them out all the time. I try to tell him good boy good boy if he his headed the right direction, but sometimes that makes him stop and look back at me.
At this point, do you think I should still be throwing a treat to get him to go through?
You're welcome.
So you are luring rather than shaping? Until your dog is 100% reliable with the treat you shouldn't be fading the lure. As your dog is inconsistent without you throwing a treat then YES you should still be throwing a treat to get him to go through.
Any time your dog misses the poles you need to move back in closer or make things easier in some other way. A dog should never fail in more than 2 out of ten attempts (and far less if your dog has low confidence). So
if your dog misses the pole ONCE you make sure your dog has NO opportunity to fail for at least the next EIGHT times. I know it sounds slow but it isn't - dogs learn really really fast this way and it finishes up with a dog that loves what it is doing and does it confidently and consistently.
I'm afraid that it does sound like you need to figure out how to communicate better with your dog. Don't worry though, if you are prepared to take responsibility for your dog's lack of understanding this can be fixed very easily - I'm sure you'll find like I did that it is a lot easier to improve my training technique than to get my dog a head transplant

. Watch the trainer-dog communication in this 2x2 video from youtube, how does it compare with what you are doing?
Hope this helps
BTW do you use a clicker?
