If you read what I said again you will see that I said “If she becomes aggressive” which she most likely wouldn’t if you had kept her in a calm state by asking her to lie down. Then you might have to do that if she were to try to bite.
In my opinion it shows the dog that biting is not acceptable. Clearly you disagree and that is fine. Either way you would want to prevent it from escalating to that level in the first place but I disagree that removing the dog from the situation will help, it will just show up again in another time or place. Once the dog is calm she will naturally want to sniff out and investigate and that will make the dog face it’s fear instead of just reacting and avoiding it.
Dogs sometimes roll on their sides or backs for their owners even without being asked to do it (just approaching) so I don’t understand why you are so opposed to asking them to do it when they have misbehaved it is not being mean and it perfectly natural in a dogs mind.
