Boxers are a playful, high-energy working breed known for their boundless enthusiasm and strong bond with family. Their square-jawed look and short coat make them easy to groom, but their exuberance means they need patient training, especially as puppies.

When does a Boxer stop growing?

A typical adult Boxer (68 lb, average activity) needs roughly 1458 kcal/day — about 0.9 lb (3.4 cups) of dry kibble per day, which works out to around $51/month at typical kibble prices. Fresh or subscription-style food usually costs more, around $583/month for the same dog. These are population-level estimates — use the calculator below for a number based on your dog's actual weight and food type, or see the Boxer feeding chart for puppy amounts by month.

- Boxer cardiomyopathy (arrhythmogenic right ventricular cardiomyopathy) is a well-documented heart condition in the breed.
- Cancer rates, especially mast cell tumors, are notably higher in Boxers than in many breeds.
- As a brachycephalic-adjacent breed, they have some heat sensitivity and are prone to bloat given their deep chest.

Larger breeds carry more weight on developing joints. Many owners start a glucosamine/chondroitin or omega-3 supplement during the growth phase rather than waiting for stiffness to appear.

Is a Boxer a good first dog?
It can work for a first-time owner who does their homework, but the Boxer isn't the automatic beginner-friendly pick either — read the exercise and grooming sections above before deciding.
How much exercise does a Boxer need?
A lot. The Boxer needs serious daily exercise — 60-90+ minutes, ideally with a job to do (training, fetch, hiking) rather than just a walk. An under-exercised Boxer is a common source of destructive or restless behavior.
Is a Boxer good with kids?
Yes, the Boxer is one of the more reliably kid-friendly breeds, generally patient and sturdy enough for boisterous play. Always supervise young kids with any dog regardless of breed reputation.
How much grooming does a Boxer need?
About as wash-and-go as it gets. The Boxer needs minimal brushing and rarely requires professional grooming.
