Senior dog peeing at food bowl

I have a 17 year old treeing feist mix female. There are no other animals in the home (other dog died just over a year ago). She was spayed at 6 months old. She frequently urinates in front of her food bowl.

It FEELS like she does it when she doesn’t like the food she is given or something. But I really have no idea. How can I stop her from doing this? She never used to do this, but now it’s ALL THE TIME. Basically since our other dog (younger boy) died it seems like! And yes we take her out before eating etc but she will still do it anyway.
