The perfect character dog

I have owned labs, retrievers, and spaniels and my Jack Russell has more personality than all of them combined. She is determined, clever, and completely unimpressed by commands she finds inconvenient. She has a way of looking at me when I ask her to do something she disagrees with that communicates volumes. She is also fiercely loyal, sleeps on my pillow, and treats my lap as her personal property. An absolute character.
