An 11-month-old entire female bulldog mix was presented for stranguria and pollakiuria of several days duration which had progressed to anorexia and abdominal pain. A diagnosis of uroabdomen was made following triage ultrasound and abdominocentesis. Despite additional diagnostics including contrast urethrogram, intravenous pyelogram, abdominal ultrasound and abdominal exploratory surgery, no inciting cause of the urine retention and uroabdomen was identified. After ruling out other possible causes, obstipation was suspected as the cause of compressive urethral obstruction leading to the uroabdomen. Clinical signs resolved completely after intraoperative deobstipation. Urethral obstruction with resulting uroabdomen is a severe complication of obstipation which has not been previously reported in dogs. Since constipation is a common presenting complaint to veterinarians, urethral obstruction should be considered as a possible sequela, given that patient history for both can be similar.
