10 classic movies with animal co-stars

[Catherine]

There have been many movies with animals in them. These are movies where the animal played  an equal part. 
Some of the stars were young and just starting out. Seeing them play with an animal partner would be interesting and entertaining.

I have never heard of most of them. I think I have only seen one of them. I definitely want to see the one with a T Rex detective. 
The fact that Whoopi Goldberg plays the human side of the partnership makes it even  better.
I don't know where we would find these movies, but they are out there somewhere and it would be worth searching.
