Agility With A Newly Deaf Dog

I'm working on my handling of Jake in agility training realizing that he's deaf. It's weird to be thinking "he's deaf" because I find myself saying things quietly or not at all while I'm concentrating on my body language and on getting the heck out in front of him so he can see me (and I thought I had to move fast with Tika!), but I think that--as I and others have noticed-- my body language includes my face and mouth movement and I think he does still hear *some* things, so I have to remember to say everything I used to *and* to do more and different body language. It's very odd to remember to do both. Or maybe it's odd that I have to work hard to remember to do what I've been doing all along!
