Gentle Leader

I bought the Gentle Leader for the dogs this weekend.  After reading all about it, online and the directions that came with the collars, I thought I'd give it a try.  I haven't watched the video yet, though I will.  I put the collar on a dog, gave him/her treats and cooed at them, then took it off.  I did this several times, leaving the collar on for longer periods of time until I got the leash attached to Bailey's.  He trotted along beside me but as soon as I tried to turn him, he stopped dead in his tracks.  I'm sure the video will help me here.

I didn't get them to the park this weekend.  I know this is key to getting them other-dog-friendly, but I'm afraid to take Bailey.  Missy is fine, until the other dog tries to introduce himself to me, and Missy gets jealous.  But she's good when I throw the ball to her.  Bailey, on the other hand is just not friendly.

Hello!

We'll be traveling soon from Columbia, SC to San Francisco via Rapid City, Denver, San Diego (I know, it's out of the way, but we have a meeting there), and Palm Springs with our two dogs.  We've never done anything like this before and are a little nervous about it.  There are pet friendly hotels on our way but our dogs are not as other pet friendly as we would like.  We'll be working on this for the next couple of months before we go.  Any tips would be helpful!
