How Big Is a Full-Grown Boxer Dog?

An exuberant athlete with boundless energy and a steadfast disposition, the boxer dog is an ideal pet companion with which to share an active lifestyle. Boxer dogs are not for everyone; like most dogs, this breed requires commitment, exercise and stimulation. In return, the typical boxer dog showers its guardian with affection, and is loyal and patient with children. If you're considering adding a boxer to your home, one of the first things you may be interested in knowing is this popular breed's size when fully grown.

  1. General Size

    • The American Boxer Club specifies the ideal standard for the boxer breed. That is described as a solidly built medium-size dog. Males and females differ in height. A fully grown male dog usually stands 23 to 25 inches at the withers, which is the highest part of the shoulders. Female dogs are a bit smaller; expect full-grown females to stand 21 to 23 inches at the withers. Like many breeds, the male boxer dog is larger-boned than its female counterparts.

    Weight

    • Ideally, boxers are lean with well-toned muscles; however, like any dog, a boxer can quickly become obese if given a poor or inappropriate diet and limited exercise. Although there can be wide variations in weight, the fully grown male boxer dog can weigh anywhere from 65 to 85 lbs., while the female's ideal weight is between 50 to 65 lbs.

    Body Characteristics

    • The boxer dog is a natural athlete, designed for speed and endurance, according to boxer expert and author Stephanie Abraham. The body is considered to be "square," with a barrel chest, an elegantly arched neck, and a firm and straight back that slopes slightly to the tail. Its muscles are well-defined and hard and smooth under its coat, which gives it a stiff and authoritative look.

    Age When Fully Grown

    • Your boxer puppy will grow rapidly when young, and may reach his final height at one year of age; however, the boxer dog at this stage is usually a much thinner and underdeveloped version of the adult boxer. The boxer dog typically does not fully reach maturity and fill out completely until approximately three years of age.

    Comparison to Other Popular Breeds

    • If you need help visualizing what a fully grown boxer dog looks like, you can compare this breed to a fully grown Dalmatian, pointer, Airedale terrier or flat-coated retriever dog, although the girth and length of the dog may vary an inch or two.
