As a present for their fourth wedding anniversary, Nathalie decides to give her husband Jean-Pierre, a Mont Blanc pen. Jean-Pierre, trying to be a bit more original, decides to go to a pet shop to find a gift she will like. He is sold on a cute white English bull dog that is only a puppy. Little does Jean-Pierre realize how the gift to Nathalie will change his life.Like with any pets, a dog needs to be trained properly, something that goes wrong from the start. Nathalie indulges the little animal, while Jean-Pierre suffers because the lack to control. What to do? The pet shop has a policy of not return, so they are stuck. Little by little, their marriage suffers because of their different views.A visit to an animal psychologist is necessary. The woman they come to see has no concrete ways to help them. She only stares the dog, not even offering a solution to their problem, asking for 100 euros per visit. Their differences end up breaking them. As a way to fight his loneliness Jean-Pierre sees a billboard advertising English bull dogs. He decides on a female one, this time around. Meeting at a park by chance, Jean-Pierre and Nathalie, each with a dog, finally realize how much they have missed each other. Why, even the dogs love being together!This was Claude Berri's final film. The director died suddenly as the film went into production. Francois Dupeyron, the director of "Monsieur Ibrahim" finished the picture. The film is mildly funny, but it needed perhaps an edge that is sadly missing because of Mr. Berri's original plans were never carried out the way he had wanted. Alain Chabat makes a wonderful Jean-Pierre. Mathilde Seigneur is Nathalie. Fanny Ardant has nothing to do in her three scenes in the movie. Do not be surprised if Hollywood is not planning a remake with the cutest dogs money can buy.
