I've never owned a boxer of either gender, but from what I read while Googling your question, male boxers can get up to 66–70 lb (30–32 kg). Are you concerned that your dog is not at a healthy weight? I'm sure your vet could offer guidance and reassurance. If you're considering getting a boxer and just want to know how big he might get, there's plenty of information about it on the internet. You can find forums to discuss the breed with other owners.
