Ace and Klea go to dog parks together, play out in back yard, nap together, fight over toys, play tug of war with the rope toy or sometimes just a stick and compete for attention from their 2 moms. This is all typical of siblings even though they are not related - they act like they are sister and brother. Ace loves squirrels and barks at them- Klea loves to bark when Ace is barking so it is noisy many times. The water bottle or bad dog spray comes in handy when they are really fighting with each other. Ace hates it and backs off- Klea barks at the bottle and wants me to spray her in her mouth. They are so different in personalities. very interesting to watch.
