Pollakiuria: Why is My Dog Urinating more Often?
Pollakiuria is a fun word to pronounce (pol′ă-kē-yū′rē-ă), but it’s certainly not a fun symptom to deal with. Pollakiuria means increased frequency of urination. Dogs with this symptom ask to go outside more frequently than normal (often, round the clock), and the well house trained dog may begin leaving puddles in the house.
Pollakiuria caused by lower urinary tract disease
Pollakiuria is most commonly caused by abnormalities within the lower urinary tract, consisting of the bladder and urethra. The urethra is the narrow tube that transports urine from the bladder to the outside world.
Lower urinary tract diseases often cause dogs to sense the need to urinate well before the bladder is full, and the puddles produced are quite small. If ever you’ve experienced a bladder infection, no doubt you can relate to this sensation.
Common lower urinary tract maladies that cause pollakiuria include:
- Bacterial infection within the bladder, aka bacterial cystitis
- Stones within the bladder or urethra
- Tumors or polyps within the bladder or urethra
Pollakiuria caused by increased thirst
Some diseases causing pollakiuria are associated with increased thirst (polydipsia). Excess water intake and excess urine production (polyuria) go hand in hand. The bladder fills more rapidly and frequently, and the puddles produced are quite large. Causes of increased thirst and urine production include:
1. Hormonal imbalances
- Diabetes mellitus
- Diabetes insipidus
- Hyperadrenocorticism (Cushing’s disease)
2. Kidney disease
- Chronic kidney disease
- Pyelonephritis (kidney infection)
3. Liver disease
- Cortisone containing products
- Anti-seizure medications
