Because this looked too fun. :D

Rrhex is a Corgi, so the first panel (normal) is a Corgi. :)
The Equine slot is a Paint horse; chose the breed because of the spotting. :)
The Feline slot is a lion, because FLOOFY MANE.
The Arthropod is a centipede. Because reasons. :)
Ursine is based off an Asian bear. BY THE WAY, I love drawin' bears and NEVER get asked to do so. WHYYYYYY?!
Fish slot, I chose a Channel Catfish. BARBELS OMG!!!
For the Marsupial slot, I went with the Thylacine. :)
For the Mustelid, I went for the Honey Badger. 'Cause Honey Badger don't give a shit!!!
For the Amphibian, I went with a salamander. I love them. :)
For the Reptile I made a Velociraptor, which is sorta close enough.
For the Primate one I chose the Mouse Lemur. Because I hate most primates. :P I like non-human-looking ones though!
For Avian. Had to go for the Great Blue (merle) Heron!!!
For Cervine, I did a Fallow stag.
For Bovine or Porcine, I went with a Brahman bull. THAT, BTW, IS PROBABLY MY FAV. I love that face. :)
For the Canine/Other, I chose the Saiga Antelope. Because they are dying and we may lose them, and so many people don't even know they exist. :(
