*Looks up what a Leucrotta is*
Oh! You mean the Andrewsarchus! Yeah...that's the artist (my) interpretation of a real creature that existed in the Eocene. Essentially, in the Eocene, an extinct branch of Ungulates (pigs, deer, goats, hippos, etc) that we only know from the Hell Pigs (Entelodonts), and the skull of the Andrewsarchus.

Andrewsarchus is believed to have fit the role/shape of modern Wolves, but 5 feet tall.
From its heritage/cousin species, was likely hooved and not as much a ball of fur (more akin to a deer's fur).

The Leucrotta seems to be more a chimera of modern ungulates that by chance looks similar.
