- There are 5 size groups: Toy, small, medium, large and giant. The AKC places the Boxer in the medium size group; though albeit, medium-large is more accurate. The KC (Kennel Club - UK) considers him to be large.
Having the Boxer dog being classified as 'medium' by some clubs surprises many, seeing that, per the AKC, males should range from 23-25 inches (58.42-63.5 cm), with females 21.5-23.5 inches (54.61-59.69 cm). There is no official weight range, however males are typically between 60-70 pounds (27-32 kg) and females from 55-65 pounds (25-29 kg).
And this being said, there are some Boxer dogs that exceed this size range, reaching upwards of 100 lbs (45 kg).
In regard to this sort of size bracketing, there are inconsistencies, where sizes overlap each other.
In regard to the AKC, let's look where the Boxer dog fits in with other breeds...
Toy - Dogs in the toy group are tiny; this ranges from the smallest of all, the Chihuahua with a desired max weight of 6.6 lbs to the much larger Pug that typically falls between 14 and 18 pounds (6.35 and 8.16 kg).
- Breeds in this grouping include the Jack Russell Terrier that is generally between 14-18 lbs (6.35 and 8.16 kg) - notice that this is the exact same as the Pug and the Boston Terrier at 10 to 25 lbs (4.5 to 11.33 kg).
- There are many dogs in this grouping, though most are smaller than the Boxer. This includes the Brittany at 35 to 42 lbs (16 to 19 kg), the English Springer Spaniel at 35 to 55 lbs (16 to 25 kg), and the Whippet at 15 to 31 lbs. (6.8 to 14 kg).
- Here, you'll find the German Shepherd which is smaller than the Boxer at 49 to 88 lbs (22 to 40 kg), the Golden Retriever, which is just about the same size as the Boxer at 55 to 75 lbs. (25 to 34 kg), and the Rhodesian Ridgeback that is larger than the Boxer at 71 to 86 lbs. (32 to 39 kg).
Giant (unofficial) - The AKC sees giant breeds as 'large'. This includes the Great Dane at 99 to 200 lbs. (45 to 90 kg), height 28 to 34 inches (71 to 86 cm) and the English Mastiff at 120 to 230 lbs. (54 to 100 kg).
