Well I emailed back and forth with a representative of GEB for a few days, asking as many questions that I could think of. My decision is this:
I will not raise for GEB.
I'm not going to go into reasons, except that they have very different style/technique of training than I am used to. This is not to say I am set in my ways and refuse to try different techniques, because that's false. I've been doing positive reinforcement with Fala and it's going well. However, the techniques GEB uses, to ME, do not seem beneficial or helpful to the guide dogs in training. When I asked the representative about this, she did not write back. So... I made the very easy decision not to raise for them.
Am I bummed that I won't be raising in the near future? Yeah, of course I am. I was excited at just the possibility. But I am not sad with my decision. I know it's the right one.
So, back to enjoying Fala and being excited for the day when Jake and I get a little puppy of our very own. :)
