Must Love Dogs is a 2005 American romantic comedy film based on Claire Cook's 2002 novel of the same name.
Meanwhile, Jake is talked into taking Sherry to see Doctor Zhivago.
Sarah notices Jake leaving the theater afterward, but while discussing the film with him she notices Sherry and realizes the two of them are on a date.
Jake is confronted by Sherry at an art gallery; she is curious why he did not call her, but again Jake does not seem interested.
Charlie then hands him a printout of Sarah's dating profile and tells Jake he has a date with her the next day at a dog park.
Eventually she dives in and swims over to his boat.
