Tan-and-white terrier mix, blue collar

I lost my tan-and-white terrier mix yesterday around 3pm after walking near SE Clinton Street and 36th Ave in Portland. He’s about 18 pounds, with a blue nylon collar and a red heart-shaped tag that reads 'Milo'. He has a crooked left ear and a tiny white star on his left shoulder. Milo is friendly but gets anxious around bikes, and I’m really worried he’ll wander off farther. If you’ve seen him, please get in touch—he’s been my constant companion since I adopted him last year and really means the world to me.
