Roo, I think you are
This is the most beautiful pet of the day - Roo, a long hair Chihuahua. She has a brother (Elliot the cat) and another brother (Tycho), but she is in charge and her brothers know it. She is a rescue dog, and has, in effect rescued me. My daughters have moved out, and my husband works at night, so Roo is all it takes to make a bad day, or lonely day better. Her favorite thing to do is lay in the sun or go for a nice long walk.
Roo is an amazing dog. She was left outside a pet store with just her leash and she adopted us. When we first got her, we knew she had been abused and the first day she actually came to sit on my lap was an amazing day. She still eats one kibble at a time and hides when voices are raised, but she is the most loving and affectionate lap dog you ever want to meet. She is very expressive and loves to "jump" and play ball. She will also let us know when our cat is eating his food (it's kind of like Lassie letting people know that Timmy fell in the well). She will come an get me to remove the cat.
I could go on and on about this dog. Truth be told, she saved me. She makes me smile. She licks away tears. She climbs up on my lap and falls asleep and follows me around and will always be at the door when I come home. She's extremely trusting and very protective of her family. I hope you find her as special as I do.
