The Loop 

Humans begin to experiment brain improvement on animals and make them speak like a human. yadayadayada, the animals start becoming one with society, with many prejudice problems....

Humans seem to be breathing in particles in the air that cause their system to not work. Every human has to wear masks. Jane, a Golden Retriever, loves humans and their way on how they do everything, until she realizes the truth about humans.

Humans are now extinct and the anthro animals have replaced their lives. Jane the dog thinks they should give humans a second chance at life. Whereas Dexter the cat disagrees because of the damage they did to the world. Who wins this argument and changes society forever? 

Since Jane won. Humans are back, but they're like feral animals. Animals begin to experiment brain improvement on the humans and make them speak like a animal. the humans start becoming one with society, with many prejudice problems, and even a leader human, who is like a Hitler 2.0, was the first human to be made. And all the segregation stuff from when humans were around are back. But instead of black & white, its human & animal.

A war rages on. Jane realises her mistake. Dexter was right. Now the world is in chaos. The humans got dibs on all the military weapons for war and left the animals with nothing. The animals think they'll fail the war. But do the animals really need weapons though? the animals have fangs, talons, wings, speed, claws, horns, and more things that humans don't have. Maybe the animals might have a chance to win this war after all.

The animals have upgraded to robot parts. Everyone is happy because with these parts there's so many positives. Since the Humans VS Animals War, humans are extinct again, but it turns out there's a group of humans living in an underground base building something big & possibly quite dangerous
