About this calculator
This calculator is designed to help veterinarians calculate a total fluid rate in small animal patients based on their body weight, degree of dehydration and anticipated ongoing losses (e.g. vomiting, diarrhea, polyuria, panting, etc).
The maintenance fluid rate is calculated based on the following formula: 70*BW(raised to the power of 0.75)
