Boxer size questions

How big does a Boxer get?

The American Kennel Club gives 65 to 80 lb (29 to 36 kg) for males and 50 to 65 lb (23 to 29 kg) for females. Female range derived: male range minus 15 lb. Individual dogs can fall outside a breed range, and a mix or a dog from working lines may be larger or smaller.

When is a Boxer fully grown?

On this curve a male reaches half of adult weight at about 19 weeks (4 months), 90 % at about 42 weeks (10 months) and 95 % at about 59 weeks (14 months). On this curve a female reaches half of adult weight at about 18 weeks (4 months), 90 % at about 45 weeks (10 months) and 95 % at about 63 weeks (15 months). These ages come from the shape of the published growth chart for large dogs, scaled to the AKC weight, so they describe a typical dog, not a particular one.

How much should a Boxer puppy weigh at 6 months?

A typical male is about 49 lb (22 kg) and a female is about 40 lb (18.3 kg) at 26 weeks on this curve. The range for healthy puppies is wide, so use the calculator above with your own puppy’s weight.
