Okay wow. I do have a young kid, and I am not particularly a dog person, and if my kid went upstairs and into a host's bedroom (after explicitly being told not to) and tried to drag a dog out from under a bed (after explicitly being told the dog was not good around kids), then . . . yeah, that would be my kid's fault? And I suppose by extension mine as well, but this is an eight-year-old child, who by now should theoretically have the brain power and impulse control to be making his own decisions about whether to follow rules or not. (And if you know your kid lacks that level of impulse control, then sure, it's your fault if you leave him where he can cause trouble instead of requiring him to come out to the porch with the adults and play on the iPad there.)

The one thing I might have done differently is close and lock the bedroom door to keep the dog isolated. "Screaming spawn" and "leash your kids" attitude aside, holy crap, the dog doesn't hate kids, the dog is afraid of kids, and that's what LW should tell people rather than "the dog isn't friendly." Jesus. (Then you'll get parents telling you it's okay, their kids are really friendly and gentle, though. Oy.)
