Benadryl Dosage Calculator for Dogs

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:

$$\text{Dosage (mL)} = \frac{\text{Dosage (mg)}}{\text{Concentration (mg/mL)}}$$
