Dehydration in animals can occur due to

• A. Vomiting
• B. Blood loss
• C. Diarrhea
• D. All of the above

Answer: (D)

Dehydration happens when water and electrolytes are lost faster than they are replaced. Vomiting removes gastric fluids and electrolytes, reducing the animal’s fluid reserves. Diarrhea acts through the same principle but via rapid loss of fluids and electrolytes from the intestines. Significant blood loss lowers circulating fluid volume, shrinking overall body water and contributing to dehydration and shock. Because each route can create a net fluid deficit, any of these conditions can lead to dehydration, so all three are possible causes. In wildlife rehab, this understanding guides fluid therapy: provide oral rehydration when possible, escalate to IV or subcutaneous fluids with electrolytes as needed, and treat the underlying issue while monitoring hydration status through weight, mucous membranes, capillary refill, and skin turgor.
