Proper hydration is one of the most overlooked—but essential—aspects of your pet’s daily health. Whether you’re caring for a playful puppy, a senior cat, or an active working dog, water supports every system in the body. It affects everything from organ function to energy levels, and even a small drop in hydration can lead to bigger problems.

At WesVet Animal Hospital, we want pet owners to feel confident recognizing dehydration, knowing when to seek care, and building everyday habits to keep pets well-hydrated.

Why Hydration Is So Important

Water does more than quench thirst—it powers nearly every process in your pet’s body. Proper hydration:

  • Regulates body temperature
  • Aids digestion and nutrient absorption
  • Flushes toxins through urine
  • Cushions joints and tissues
  • Supports organ and immune system function

Even mild dehydration can affect your pet’s comfort and health. For pets with chronic conditions like kidney disease or diabetes, staying hydrated is even more critical.

Common Causes of Dehydration in Pets

Dehydration can occur when fluid loss exceeds intake. Common triggers include:

Recognizing Signs of Dehydration

Early recognition is key. Look for:

Mild to moderate signs:

  • Dry or sticky gums
  • Lethargy or low energy
  • Decreased appetite
  • Reduced skin elasticity (a gentle pinch test on the neck can help)

Severe signs:

  • Sunken eyes
  • Weakness or collapse
  • Panting without exertion or heat exposure
  • Rapid heart rate or labored breathing

Cats often show subtler signs than dogs, so it’s important to monitor behavior changes closely.

How We Diagnose and Treat Dehydration

When you bring your pet to WesVet Animal Hospital, we’ll begin with a full physical exam and review of symptoms. We may also perform:

  • Skin turgor and gum moisture checks
  • Vital signs (heart rate, respiratory rate, temperature)
  • Diagnostic testing (bloodwork, urinalysis, fecal testing) to identify underlying causes

Treatment Options

  • Mild dehydration: Encouraging fluid intake, adding moisture to food, or offering pet-safe broths
  • Moderate to severe cases: Administering subcutaneous (SQ) or intravenous (IV) fluids

  • Hospitalization if intensive monitoring or supportive care is needed

What Happens If Dehydration Goes Untreated?

Unchecked dehydration can lead to:

  • Kidney damage or failure
  • Electrolyte imbalances
  • Organ dysfunction
  • Hypovolemic shock (life-threatening in severe cases)

If your pet is showing signs of advanced dehydration, seek care immediately.
