Example of using an isotonic crystalloid solution for rehydration: 

  • Dog weighing 22 lb (10 kg) with 7% dehydration
    • 7% of 10 kg = 0.7 kg = 700 mL
    • 66 mL/kg/day = 660 mL over 24 hours or 330 mL over 12 hours
    • 700 mL + 330 mL = 1,030 mL over 12 hours = 86 mL/hour for the first 12 hours 
*Do not induce emesis if there is a concern for esophageal obstruction when the foreign body is vomited, such as with a large object. Emesis is contraindicated if there is a concern for caustic mucosal damage (eg, from any acidic/alkaline chemicals, batteries).
