You need to take this dog to a vet, any diet restrictions would depend on the type of stones the dog has. This can only be determined after the stones are removed and sent to a lab for analysis.
If this dog has a chronic condition, no diet alone is going to fix this. You may need the expertise of a specialist.
Hope this helps

PS: what breed is the dog? Age?
