Ok, so to help with the search, he is a grey Andalusian. He has siblings with names of the major gods/goddesses. I'd like to find something masculine but maybe easy to pronounce?
The only name I have found that I like so far is Calixtrato, but I think it may be too close to my dog's name.
I'm searching through the links y'all sent me now!

ABRAXAS: Greek myth name of one of the horses belonging to the sun god Helios. It is also the name of a demon of lies and deceit. The letters of the name add up to 365, the number of days in the year. It has been found in Greek magical texts and may be related to the word abracadabra which may derive from Aramaic avra kedabra, meaning "I will create as I speak."
BALTAZAR: Variant spelling of Greek Baltasar, meaning "Ba'al protect the king."
EUKLEIDES (Εὐκλείδης): Greek name composed of the elements eu "good" and kleos "glory," hence "good glory."
METHODIOS (Μεθόδιος): Greek name derived from methodos, meaning "method
MINOS (Μίνως): Greek name possibly derived from an ancient Cretan word for a "king." In mythology, this is the name of a king of Crete, son of Zeus and Europe.
Hyperion was one of the Titans and he was associated with light.
Hesiod was actually a historian, but he recorded a version of the Greek creation myths/history of all the gods and goddesses in his Theogony.
Castor and Pollux were twins, both associated with horses. Castor was the mortal one and Pollux was the son of Zeus.
This is a better site than the ones I offered earlier. It's a little more organized, so you can get to lists of sea gods or sky gods or whatever other theme might appeal.
ETA: Odysseus is the one who conceived of the Trojan Horse, so might be a good pick if your guy is the crafty/troublemaker/in and out of scrapes type. The Latin spelling is Ulysses, if you like that better.
