Dog nearly drowns to save money.
And thus ends the careers of Animal Trainer Raymond W. Beal and Brian Turi.
The scene as filmed required a dog to swim in turbulent water. Normally the water would be disturbed by the special effects crew while a diver assisted, and via post effects and clever editing would make the scene look very chaotic. A water mist would be sprayed into a fan to produce the desired effect.
Whether due to lack of talent or deliberate stupidity, the director, special effects team and the animal wrangler and producers allowed the animal to be forced into dangerous water which drove the animal under while it fought in vain for its life before being pulled out at the last moment.
This crew violated standard ethics by doing so.
It should be made clear that no motion pictures are made this way and it brings shame to the industry. This is a unique, disgusting case and anyone who's name is attached to this picture should not be hired again for any reason.
