Paint isn't the way to go—it will certainly jitter. I usually use an animated mask on a color corrector. The trick is going to be to get your masking to match the original real shadow as closely as possible. You'll probably want a separate shape for each of the dog's legs. Roto the original shadow. It can be pretty loose since the shadow is soft. Once that's done, it's a matter of color correcting the patch until it matches.
I usually start by looking at just the Green channel and use the Master RGB Gain control to get that to match as closely as possible. Green carries most of the luminance information in an image, so if you get that channel right, the other two will also usually be very close.
