It would depend on the individual dogs. Staffs (at least American Staffordshire Terriers) are fairly similar in type and size to a Boxer. Both have similar energy levels and exercise requirements. If both individual dogs are sociable with others, and if they are of opposite gender, you would stand a fair chance of them getting along. However, remember that both breeds can be "scrappy" and you would want to monitor them when together, and separate them when you leave the house. Just in case.
