Why Is My Shih Tzu Drinking So Much Water?
If you’ve noticed your Shih Tzu lapping up water more than usual, it’s natural to worry. Increased thirst, medically called polydipsia, can be a red flag for several health issues. While it might be something simple like hot weather or extra exercise, it can also signal underlying problems that need veterinary attention. Let’s explore the common reasons and what you should do.
Common Causes of Excessive Thirst in Shih Tzus
Dehydration
Your Shih Tzu may simply be dehydrated after a long walk, play session, or if they haven’t had enough water during the day. Brachycephalic breeds like Shih Tzus are prone to overheating, so they may drink more to cool down. If the weather is hot or your dog has been active, increased thirst is normal. However, if it persists, look for other signs.
Diabetes Mellitus
Diabetes is a common endocrine disorder in Shih Tzus, especially middle-aged to older dogs. One of the classic symptoms is excessive drinking and urination. Other signs include weight loss despite a good appetite, lethargy, and recurrent infections. Diabetes requires lifelong management with insulin and dietary changes.
Kidney Disease
Canine kidney disease often leads to increased thirst because the kidneys lose their ability to concentrate urine. This is more common in senior Shih Tzus. Accompanying signs include decreased appetite, vomiting, bad breath, and weight loss. Early detection can slow the disease’s progression.
Cushing’s Disease (Hyperadrenocorticism)
Cushing’s disease results from overproduction of cortisol, often causing increased thirst and urination. Shih Tzus are predisposed to this condition. You may also notice increased appetite, a pot-bellied appearance, hair loss, and panting. Diagnosis requires blood tests and sometimes an ultrasound.
Urinary Tract Infection (UTI)
A UTI can make your Shih Tzu feel the need to drink more to flush out bacteria. Look for frequent urination, accidents in the house, blood in urine, or licking the genital area. UTIs are treatable with antibiotics.
Medications
Certain medications, such as steroids (prednisone) or some seizure drugs, can cause increased thirst as a side effect. If your Shih Tzu has recently started a new medication, discuss it with your vet.
When to Consult a Vet
If your Shih Tzu’s increased thirst lasts more than a day or two, or is accompanied by other symptoms like lethargy, vomiting, weight loss, or changes in appetite, schedule a vet visit. Your vet will perform a physical exam, run blood tests, and possibly a urinalysis to pinpoint the cause. Early intervention is key for many conditions.
What You Can Do at Home
- Monitor water intake: Measure how much your Shih Tzu drinks daily. A rough guideline is about 1 ounce per pound of body weight per day, but it varies.
- Keep a log: Note any changes in behavior, urination frequency, or other symptoms.
- Provide fresh water: Ensure your dog always has access to clean, cool water.
- Avoid self-diagnosing: Never assume it’s just dehydration or anxiety.
Key Takeaway
If your Shih Tzu is drinking more water than usual for more than a day, consult your veterinarian to rule out health issues like diabetes, kidney disease, or Cushing’s disease.

If your Shih Tzu’s excessive thirst persists beyond a day, consult your veterinarian to rule out diabetes, kidney disease, or Cushing’s disease.
