Rich, Your pup looks like a fire to me - he's got orange flames and a smoldering, smoking appearance, just waiting to explode and since he is going to be a tracker - relentlessly pursuring over all obstacles through the woods to get at his prey that knows to fear and run from him - I have to go with Terra Fuego (Latin for Ground and Spanish for Fire) "GROUND FIRE" because that is what ya got - Ground Fire! Or if you want the two syllable or less - Fuego.
Or you can pick any other languages to come up with this name.
Complete Spanish - Terreno Fuego
Latin - Terra Flamma
