Pluto Mehra, the dog, plays a pivotal role in the multi-starrer film.
"In order to make the dog act and lick him, Farhan put a face pack of vanilla ice cream all over the face. And then the dog came running and licked it all," Ranveer Singh, Farhan's co-actor in the film, told reporters here today.
Farhan said it was very exciting for him to have the dog lick his face.
Directed by Zoya Akhtar, the cruise drama stars Anil Kapoor, Priyanka Chopra, Ranveer, Anushka Sharma and Farhan.
Describing it as a family film with a difference, Anil said, "It has Zoya's style of filmmaking. It is of world standards."
The story is about how a family comes to terms with each other while on the cruise trip.
Ranveer said the film also features a song with a 4.5 minute non-stop dancing in one shot. "Dil Dhadakne Do" releases on June 5.
