More: We have 4 toy and tot sized rat terriers and Sansa was our foray into "big dog" territory, she's 20-25lbs but think's she's a little too. A very smart, sassy, talkative pup (her wake up chatter includes "arroooo-arroooo). I'm trying to teach her to say "I love you" but we aren't there yet. She loves to play outside and go on walks and hikes unless it is raining, she does not like dirty paws (but then who does, lol)! :)
