Screenwriter Penelope Killed Off Dog -- For What Purpose ?
The screenplay of the film is brilliant. Screenwriter Penelope Gilliatt (spelling ?) must have had a good reason for killing off the dog during the scenes in Hyde Park in London. Any ideas ?
My guess is that you have to factor in the scenes that follow the ugly Hyde Park collision. Remember that later the same day Alex and Bob and the kids are engaged in drawing pictures of their day in the park. The message seems to be that Bob can handle the death of a relationship with his usual nonchalance. The collision is never referred to again in the movie, and obviously Dr. Hirsch knows nothing about it, so why would HE care ?
Based on that reasoning, I would say that we have a love triangle, and two of the "sides" show they can handle an unwelcome jolt very well, leading one "side" to assume coldly that the other two could handle his permanent disappearance very well. The flaw in Bob's reasoning is that relations between household pets and masters are very different from interpersonal relationships. Owning more than one dog, as do the friends who hire Alex and Bob to babysit the kids, is very similar to owning just one dog. But a human twosome is very, very different from a human threesome. And threesomes rarely last for more than a decade.
