Using canines and a few other animals as test subjects, they changed the dogs, but the side affects were too dangerous, and they couldn't do the same on humans. These monster creatures were supposedly destroyed before the humans all died off, but they weren't, and now the monster canines have taken over the earth, along with the very few other species that were mutated, which become the prey source for these beasts.

There's one idea, and I can probably come up with a few more if that doesn't peak your interest.

Hm, I like it, but I'm interested to hear some more?
