So everybody who used to be homo sapien was now a dragon.
Alas that had given deer a niche to fill up the space
formerly occupied by humans,so the dominant intellient
species were now anthro deer,with brainpower and high tech gadgets to boot.
So you and Joey looked up stupidly as a flying spaceship from the Anares star came whizzing
over and headed to the futuristic city
miles away.
It seems the deer had got involved in less interspecies warfare
and thus their civilization was about a millenia ahead of the vanished 21rst century
human civilization that you and Joey had
wiped out.
In "Star Trek " terms,the deer people have a decent grip on space travel and are
now exploring their past through
"Time Engines"
And they don't wan't humanity to come back and thus have made sure
big dragonnish reptiles like you
Joey and the others gobble up and primates that pop up.
And just in case the dragons are thinking about eating deer people,they've got nifty slave collars and laserblasters
to bring troublesome dragons back into line
