Just bought my first snake, a baby ball python. I have photos and a question.

[The Serpent Merchant]

Not sure I like this guys angle...a snake is not a dog...you cannot "dominate" or train them to be submissive ...I see this as just stressing out a hatchling that should be just left alone. A hatchling knows its vulnerable, so they can choose to be more strikey.
but this is just IMO

Justin is a great guy, and definitely knows what he is doing... but that video is for a specific situation. I don't think that "dominating" is the right word to describe what he is actually doing (I know that he says it himself...) what he is doing is forcing an animal into a defensive mode vs attack mode. The BP will quickly realize that biting isn't getting anywhere and "ball" up as that is their defense mechanism. This works because it operates on the most basic of all instincts, the fight or flight response. Once an animal realizes that fighting isn't going to work it will shift into flight mode (which in ball pythons is balling up lol) This isn't something that I would suggest for a new BP that is a little nippy, but rather for an established snake that is acting aggressive.
