How Big Is a Full-Grown Boxer Dog?
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.
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.
