After being driven to extinction, great bloodthirsty dinosaurs come back to life with the assistance of a demented genetic scientist. She plans to replace the human race with a super-race of dinosaurs who will not pollute the planet.
There is a scene where the Deinonychus is seen passing a pet shop window and noticing a dog inside but the scene cuts away before you see the dog get eaten. Later on the sheriff who is looking for the dinosaur finds the pet store window smashed and the remains of the dog can be seen.
If you count dinosaurs then yes, a Deinonychus is shot twice with the second shot blowing its head up. A Tyrannosaurs is disembowelled and killed with a loader.
There is also a shot of the Deinonychus eating a chicken early on in the film after the dinosaur has hatched.
