1. What is Purina Hypoallergenic Dog Food?

Purina Hypoallergenic (HA) dog food is a specialized veterinary diet designed for dogs with food allergies or sensitivities. It contains hydrolyzed protein sources that are broken down into smaller components to minimize allergic reactions.

2. How Does the Calculator Work?

The calculator uses the following formula:

\[ \text{Daily Amount (grams)} = \frac{70 \times (\text{Body Weight in kg})^{0.75} \times \text{Factor}}{\text{Calories per Gram of HA Food}} \]

Where:

\( \text{Body Weight} \) — Dog's weight in kilograms
\( \text{Factor} \) — Metabolic factor (typically 1.6 for adult dogs)
\( \text{Calories per Gram} \) — Energy content of the HA food (kcal/g)

Explanation: The formula calculates the daily feeding amount based on the dog's metabolic weight and energy requirements, adjusted for the specific calorie content of Purina HA food.

3. Importance of Proper Feeding

Details: Accurate feeding calculations are crucial for maintaining optimal health in dogs with food allergies. Proper portion control helps prevent obesity while ensuring the dog receives adequate nutrition from the specialized diet.

4. Using the Calculator

Tips: Enter the dog's weight in kilograms, the appropriate factor (typically 1.6 for adult dogs), and the calories per gram of the specific Purina HA formula. All values must be positive numbers.
