I can't speak American dog very well. There was a lot of improvisation with Uggie - like when I put the dog on the table or sometimes I follow him, sometimes he follows me. I had a lot of treats in my pocket. We worked with Omar Von Muller, the dog trainer. It was very easy because it was a big movie.
