Maybe medieval furry art could tell us something about that.

There were mythical, anthropomorphic "doghead" creatures depicted in medieval art and literature. Medieval Christians didn't seem to hold a very favorable view of them though, depicting them as barbarians; brutal beasts that may or may not eat human flesh, and holding other very "un-Christian" qualities. Sometimes they were written into stories as enemies of good Christian knights like King Arthur or whatever. Some stories would depict a doghead being baptized, and only after that were they given human form, washing away the beastliness and accepting the purity of humanity.
So yes, you will go to hell unless you renounce your beastly urges, confess your sins and accept Jesus Christ as your Lord and Saviour.
