What can cause the inability to urinate?
The causes break down into two groups. In any case, though, your dog needs to see a veterinarian immediately.
One of them is urinary tract obstruction, either due to a blockage, inflammation or compression of the urethra. The problem behind this can be
- urinary tract stones
- urinary disease
- prostate disease in male dogs …
The other category involves what is referred to as functional urinary retention, caused by dysfunction, rather than an obstruction. This can be neurologic or systemic in nature.
Urinary retention refers to incomplete voiding of pee that is not caused by an obstruction. It can happen as a complication of:
- urinary tract infection (UTI)
- injury to the bladder or urethra
- or dysfunction of the muscles coordinating peeing
Systemic causes can include:
- electrolyte disturbances
- Cushing’s disease

Urine buildup can lead to kidney failure, electrolyte issues or bladder rupture. All of these things can be fatal.
