London, Jan 16 : American actors Justin Timberlake and Jessica Biel were seen doing their bit for man's best friend, by trying to find a new home for a rescue dog.

The two were spotted putting up posters this week while hiking in the Hollywood Hills in Los Angeles, reports the Sun.

Though their busy schedule means that they hardly get enough time to spend together, they still found time to help out the dog.

The pair has been dating for quite sometime, and the one item that they have added to their exercise regime is dog walking. (ANI)
