The chandelier is shaking and making noise at Brendleberry's Antiques, but in the mirror behind Kelly (which is about to break) the chandelier can be seen hanging perfectly still.
Barks and growls were added post-production to the filming of the dog which is allegedly angry at Kelly; but the canine is visually docile, non-threatening, at times lying down minding its own business, with its mouth closed as it appears perfectly calm.
