Quick answer: Go to an emergency vet if your dog is straining with little or no urine, or has urinary signs with vomiting, lethargy, or a painful belly. See a vet within a day for frequent urination, blood in the urine, or accidents. Increased thirst and urination in an otherwise well dog should be checked soon, since it can signal kidney disease, diabetes, or Cushing’s disease.
