In The Bourne Identity, it’s implied that a dog is killed. They’re hiding out in a farmhouse where they are followed by an assassin. The sudden disappearance of the dog tips Bourne off that something big is about to happen and he takes action as a result.
And of course, how could I not mention A Boy and His Dog, where the relationship between Don Johnson and man’s best friend is taken to a new level and the sexy but conniving girl is killed to feed the dog.
The worst part of Stephen King’s Tommyknockers was what they did to the dog. They way it was described in the book at least. I vaguely remember seeing the movie but can’t remember how bad the dog got it.
Merle actually is a man. You can only be “in drag” if you’re impersonating a man (or woman).
And now, if you will, a corollary to “Dogs are gods in the movies”:
Cats are scenery in the movies.
Discuss. Or not. 'S all the same to me.
Minor nitpick/hijack, but these days I think drag can also just mean costume or outfit you don’t normally wear. For instance leather drag is putting on all your leather biker clothes just to go out to the local leather bar. Sometimes I refer to my business suit as my “business drag” because I don’t like dressing that way on a day-to-day basis.
I have a god named Spot.
You don’t say? 
Not just these days. I’ve seen “drag” to mean “costume” or “uniform” as far back as the 40s. It was only recently that it was used to mean only dressing in the manner of another gender.
I think what I really meant in my corollary is:
Cats are props in the movies.
Discuss?.. 
Yeah, well, that’s what I get for starting a post in the morning and finishing it up in the afternoon.
Note to self: refresh is your friend.
But it was a cool dog. And worth multiple mentions, IMHO.
In Halloween, Michael Myers strangles a dog at one point.
Chanelling Steven Wright:
I have a god named Spot…
I poured spot remover on my god…
Now he’s invisible just like all the others…
