I've been wanting to get a video of Isaac coming when I blow the whistle. Sometimes it is ridiculously hard to get things on video. Seems like he never does it then way I want him to when I have the camera available.
Usually he comes running at full tilt. This time, he came right away but not running. Of course, when I didn't have the camera ready, then he ran so fast he practically skidded past me.
Still, we worked hard on his recall with the whistle. So here it is.
