A TUG Snow or The Urban Gecko Snow, is a Snow line created by Craig Stewart from The Urban Gecko. The TUG Snows come from a selectively bred Wild Caught group. Stewart believes his snows are axanthic, a genetic trait where little to no yellow is produced. The TUG Snows are also a dominate trait.
Many people have wondered if a TUG Snow is bred to a Mack Snow if Super Snows would be produced. A few breeders have in fact created Super Snows from breeding a TUG Snow to a Mack Snow.
