The Benadryl dosage is calculated using the following formulas:
For dosage in pounds:
\[ \text{Dosage (mg)} = \text{Dog's weight (lb)} \times 1 \text{ mg} \]
For dosage in kilograms:
\[ \text{Dosage (mg)} = \text{Dog's weight (kg)} \times 2.2 \text{ mg} \]
To convert milligrams to milliliters:
\[ \text{Dosage (mL)} = \frac{\text{Dosage (mg)}}{\text{Concentration (mg/mL)}} \]
