After Naanayam, Sibiraj was on the lookout for a script for his next film. Since nothing interesting turned up, he took a brief hiatus, still reading scripts. Sibiraj is a dog-lover and has 3 dogs. So, he expressed his eagerness in working with animals in a film. Director Shakti S. Rajan, who had earlier directed Sibiraj in Naanayam, came up with a script with a dog in the lead. The film is about a military-trained dog and a man, and their journey. Finally, the film was announced in July 2013. The film was titled Naaigal Jaakirathai meaning \'Beware of Dogs\'.
Sibiraj plays the second hero and will be sharing screen space with a military trained canine. Apart from playing the hero, the dog would also do several action sequences and comedy tracks in the film. Arundhati of Sundaattam fame plays the female lead. While music is composed by Dharan Kumar of Podaa Podi fame, camera is handled by Nizar Shifi and editing by the Praveen K L.
They were on the lookout for a trained dog, preferably a German Shepherd. After a search, they found a dog from Bangalore. Filming began on 9 October 2013 and has been expected to be completed by the month end. The story takes place in Coimbatore, and travels to Ooty, Palakkad and Chennai.
