If you could post what you are referring to it would be helpful.
I went and read the PH testimony from March today because I read your post and had never heard the "walking" part. I skimmed through and when I found the part in question I read it and he said that both times he let the dog out the sliding door and watched until the dog was done and let it back in.
I may have missed something, but that is what I read, again, in the March prelim. hearing transcripts.
