What breed is the dog? How old is the dog? What are her diagnoses? What type or types of stones does she have?
What is wrong with only having 1 bowel movement a day, most dogs go once or twice a day (in my experience).
But is she is a little constipated, increased water in the diet will help.
PS: If you soak the kibble in water overnight in the fridg, it doubles in size, ask the vet if you can add a spoonful of cooked lean chicken or red meat. I would still add more water.
Ask the vet about supplements, fish oil, dog multivit, etc.
Make sure she is offered a bathroom break, the opportunity to urinate at least every 4 hours (every 2 hours is ideal) Keep the bladder flushed.
