Question: what does it mean when your dog won't pee?
Answer: Obstructions in your dog's bladder or urethra can lead to urinary retention. These obstructions can be the result of bladder stones, urethral plugs, blood clots, a narrowing of the urethra (called stricture), or even cancerous tumors. Also, if minerals accumulate in the urinary tract, it can also cause an obstruction.
