Urinary Symptoms in Dogs
Most urinary tract disorders cause some disturbance in the normal pattern of voiding. There are a number of signs to look for.
Dysuria (Painful Urination)
Signs of dysuria are obvious distress during urination with straining, dribbling, licking at the penis or vulva, crying out in pain, voiding frequently in small amounts, squatting but not passing urine after many tries, and/or passing mucus, blood clots, or bloody urine. These signs indicate a disorder of the bladder, urethra, or prostate.
Pain and swelling in the lower abdomen suggest an overdistended bladder. A dog who does not pass urine after prolonged squatting or lifting of the leg is obstructed. This is usually caused by a stone, but could also be due to a tumor obstructing the urine flow.
