Ugi was one of few young pups adopted into the pack that both could remember their name and decided to keep it. As such his ‘full name’ is nothing more than tradition and never used by the pack. Frankly it being reverse-engineered to abbreviate into his real name was half a panicked decision and half a joke which quickly lost it’s humour.
Retired with his mate at 5y4m old to the pup pile.
