I looked into these in the past, because I'd love to have a burm, but can't handle the size (I'm usually on my own with the snake care). The problem I read about was knowing if they were TRUE dwarfs or not. I came across stories of "dwarves" getting 10+ feet. Seems some people will call them dwarfs to make a sale, even if they aren't true dwarfs. Not accusing anyone of anything here, but that's what stopped my research. Are there sure ways of knowing a true dwarf by look? And not just size, because the age/size thing can be misrepresented by someone just trying to get a sale. I'd have to be 100% sure before I could take the leap, as I wouldn't want to have to worry about re-homing a "dwarf" when it started reaching 10+ feet.
