I’m not sure I observed much body language of concern with that clip. Vocalizing alone doesn’t always mean problems, although with the very last moment the lab has low tail, ears back, and is arcing away from the husky.
I’d possibly advise to let them engage in some initial contact, separate the dogs for a quick timeout to keep arousal from spiking too high, too fast. Then, let them come back together and see how it goes. Be ready to interrupt again if either dog shows signs of discomfort.
