When you have to board her, you can give the kennel a small container of cooked food and instruct them to add a little to her kibble which you also can provide, my neighbor does this, with good results.
PS: If they fast or eat light for a day or two at the kennel, it will be okay.
I might start to worry at 72 hours (3 days) if they are not at least drinking water. At that point, I would want a veterinarian to look at the dog.
