Can you look carefully at the maid's right hand. The finger(A) between the thumb and index finger is not right. If you zoom in you'll see that A doesn't align with the middle finger as it should.

That is not her finger.
It is treat that she is trying to tempt the dog with.

It looks like she's snapping her fingers to get the dog's attention AND why does the ''treat'' look like a finger? And she's not looking at the dog

I don't do it like that, I have both fingers together. Anyway nowadays I only use my middle finger for .............. I'll let you guess about that.

If it's a finger it's either a mistake or deliberate.

It can't be a mistake because the rest of the painting is done in meticulous detail and anatomically correct.

So, it has to be deliberate.

Now, why would the painter paint an extra digit?
