Some of the main characteristics of this animal include a muscular body, thick bones, large feet, short hair and horns. The average weight of a bull can range from 1,100 – 2,200 pounds. This bold tattoo design is the epitome of strength and power and is commonly selected by the male gender. The meaning of a bull tattoo may vary depending on the exact design that is chosen.
