Pedialyte Dosage for a 23-Pound Dog with Diarrhea

For a 23-pound (approximately 10.4 kg) dog with diarrhea, administer approximately 10 mL/kg of oral rehydration solution like Pedialyte for each watery stool, which equals about 100-104 mL (3.4-3.5 oz) per diarrhea episode.

Oral Rehydration Therapy for Dogs with Diarrhea

Oral rehydration is the primary treatment for diarrhea in both humans and animals. While there are limited specific veterinary guidelines for Pedialyte administration in dogs, we can apply principles from human medicine with appropriate weight-based adjustments:

  • The recommended replacement volume is approximately 10 mL/kg for each watery stool 1
  • For a 23-pound (10.4 kg) dog, this equals about 104 mL per diarrhea episode
  • Administer the solution slowly using a syringe to prevent aspiration
  • Divide the total amount into smaller portions given over time rather than all at once

Electrolyte Composition Considerations

When using Pedialyte or other oral rehydration solutions, the optimal composition should include:

  • Sodium: 65-70 mEq/L
  • Glucose: 75-90 mmol/L
  • Potassium: 20 mEq/L 1

Standard Pedialyte generally meets these requirements and is suitable for dogs with diarrhea. However, sports drinks, juices, and sodas are not recommended as they typically have inappropriate electrolyte concentrations 2.

Additional Management Approaches

Beyond fluid replacement, consider these additional measures:

  • Continue feeding a highly digestible diet rather than fasting the dog
  • Consider adding soluble fiber to the diet, which has shown good results in dogs with chronic large-bowel diarrhea 3
  • Avoid unnecessary antibiotics like metronidazole, which are often overprescribed for acute diarrhea in dogs 4
  • Monitor for signs of severe dehydration including:
    • Lethargy
    • Dry gums
    • Decreased skin elasticity
    • Sunken eyes

Common Pitfalls to Avoid

  • Delaying rehydration therapy
  • Using inappropriate fluids like sports drinks or plain water
  • Completely withholding food
  • Overusing antibiotics without clear indication
  • Administering too much fluid too quickly, which can cause vomiting

When to Seek Veterinary Care

Seek immediate veterinary attention if your dog shows:

  • Bloody diarrhea
  • Persistent vomiting
  • Signs of severe dehydration
  • Altered mental status
  • High fever
  • No improvement after 24-48 hours of home care

While electrolyte supplementation studies in working dogs have shown limited benefits 5, proper hydration remains essential for dogs with diarrhea, and oral rehydration solutions like Pedialyte are generally safe and effective when administered appropriately.
