More: Pebbles earned her name by playing fetch with rocks when I got her at 3 months old. She is gentle and sweet, deferring to our 15 year old senior dog Brody. When she was only 6 months old, I gave her a scoop of food in a cup. When she finished her treat, she took the cup to the bag, scooped more food, set it on the floor and finished her snack. My silly Pebbles!
