I do not let Iggy hunt, so it is rare I get to see him stalk prey like this. It is fascinating to watch him notice the snow bunny from 100 yards away, and then circle around so he comes up next to it instead of from the front. Frankie only approaches once Iggy has counted his coup and ensured it is safe.

I love this, it makes me miss my Benjamin Grimm (Irish Woldhound) He and Iggy would of been friends. Oh and sorry to break it to you… that was a snow PIKACHU
Thank you, Angi! I wish Iggy and I could have met, Ben, too!
