Um, okay. And then the dog managed to drag the baby outside? All of this while the parent was right there "feeding the baby & the dog at the same time?"

Yup, this sounds fishy.
8 month olds do not “somehow” get out of their high chair. They might, just might, manage to go clunk out of their high chair. But if you’re in the room as you should be with a baby in a high chair you would stop them before they got that far.
