No one can diagnose your dog or prescribe treatment over the internet, nor should they try.
If it was my dog I would attempt to collect a urine sample (empty clean prescription pill bottle will do) and head to the vet (asap) to see what is going on. Get a feces sample too.
If you have been feeding raw, anything is possible.
