I've fed each of our dogs carrots this way. It takes trust in the dog (and a hope for good depth perception). Lizzie is a gentle soul. As she nears seven months with us, she has bonded to me. That's wonderful and sad. Like Gwen before her, she now recognizes when my bag is out for "good" and "bad" trips. Her mood is bright and bouncy when Ali's bag also appears as she expects to join us in Pennsylvania. She is visibly down when my bag appears on its own as she knows I will be going away alone for a business trip. At least when I am home, we get to enjoy carrots.
