The couple that walks the dog together stays together! Jessica Biel and Justin Timberlake took to the LA trails with Tina yesterday, and while they were there, Justin posted a flier for a pup that is in need of a home.

I know how pooch friendly these two are — with Jessica active in drawing attention to animal rights — it's nice to see them pitching in to find a home for a needy pup. Besides, that's how Jessica came to add Tina as a part of her family, too!

Check out more pics of their walk, and the sweet face of the little doggie on the bulletin board below.
