Which dosage unit is commonly used for veterinary prescriptions of medications?

The most commonly used dosage unit for veterinary prescriptions of medications is milligrams. This unit is often appropriate for dosing in smaller animals or smaller doses that are frequently required, as many medications are prescribed in doses that are proportional to the animal's body weight. Milligrams allow for more precise calculations, especially when dealing with medications that are potent and require careful dosing to avoid toxicity.

In veterinary medicine, being able to measure small quantities accurately is critical, especially in species that have significant variations in size, such as cats, dogs, and various exotic animals. Therefore, while milliliters might be used for liquid medications, and grams and liters can be relevant in specific contexts, milligrams remain the standard for specifying dose amounts in most prescriptions for veterinary patients.
