My Dog Is Straining to Urinate — Is This Serious?
Yes, it can be serious. Straining with little or no urine for 12+ hours is urgent, especially in male dogs where blockage can become life-threatening.

Urination problems can progress quickly from discomfort to life-threatening emergency. Dogs that repeatedly posture to urinate but produce only drips, or no urine at all, may have bladder inflammation, stones, urethral obstruction, or severe urinary tract disease. Male dogs are at especially high risk of complete blockage.
A blocked urinary tract can cause toxin buildup, severe pain, electrolyte imbalance, and collapse. If your dog is straining repeatedly without output, do not wait overnight. Triage can help guide urgency, but persistent no-urine episodes should be treated as urgent veterinary situations.
Use this page as a fast decision guide, not a diagnosis. A symptom can look mild early and become urgent later, especially overnight. The safest approach is to combine your dog's symptom details with behavior, breathing, hydration, and gum color. If multiple warning signs appear together, urgency rises quickly.
If you are unsure, choose the safer option and run triage now. The goal is to avoid missing emergencies while also reducing unnecessary panic trips. Taking two minutes to assess timing, progression, and red flags gives your veterinary team better information and helps you act with confidence.
