I have a few ideas ^^ You obviously dont have to use any of them Im just throwing them out there
For species name suggestions:
How about Vulcan Foxes? Vulcan is volcano in French and Spanish and it's also the Roman god of fire, volcanoes, and the forge.
Or Ashen Fire Foxes because the fur is black like ash and obviously the fire around their necks for the "fire" part.
This is really stretching it but Dragons foxes? Lol it just sounds catchy and you know, the fire... plus not all dragons have wings.. and below it says the fox's fur could be fire resistant like a dragons scales...
Also, for species attributes:
You could make a rule that the base fur color is always a shade of gray or black like ash, the pads match the fire color and eyes, and the markings always white [besides the tail which are black]. I think the contrast between coat and markings is cool ^^ plus it goes with the glowing markings [below]
The white markings could glow the color of the fox's fire when feeling extreme emotions
It would be cool if the Fox could control the balls of fire to do different stuff, like making fires and throwing fireballs. Although the fire always returns to them. ^^
In addition to them being mega fast, they could be able to jump super high
The fox's fur is obviously probably fire resistant but what if the fire only burns if the fox wills it, and if its powerful enough it can burn through the fur? Otherwise it only burns exposed skin on another fox, like pads and nose. Also like if a human touches it the fox can make it so the fire isnt hot.
Anyways, these are a few (or a lot XO sorry I couldnt help myself!) suggestions you can take or leave them

This species is so cool!!!!!!!! *squee* I love it!!! Too bad I cant draw, only color in otherwise I would totally be an artist!
