Good afternoon. I know how unsettling it is when your pet is acting out of the ordinary.
Polyuria, or increased urination, is seen in pets of all ages. Polydipsia, or increased water consumption, is commonly noted as well. Urine production and water consumption is controlled by the interaction between different systems within your pet’s body. Increased water consumption is noted because the body is losing more fluid via urination so the body compensates for this loss.
Causes of increased urination and drinking:
1. Environmental (Heat and humidity)
2. Urinary tract infections
3. Urinary crystals or stones
4. Kidney infections
5. Kidney disease
6. Hyperadrenocorticism (Cushing’s Disease)
7. Electrolyte abnormalities (Sodium, Chloride, or Potassium)
10. Drug induced—if giving medications
There are more causes but this shows some of the common causes.
It is important that you schedule an appointment with your veterinarian. At this appointment, make sure you bring in a urine sample to start. Your veterinarian will do a complete physical examination and my recommend routine blood work, stool sample and radiographs to explore the reason for the increased drinking and urinating.
Good luck and I hope this helps.
