Some Internet forums refer to a pug/boxer cross as a poxer or puxer, but as of August 2014, the cross is not recognized by popular registries for hybrid dogs. Names of hybrid dog types are usually combinations of the names of the parent breeds.
Puppies bred by crossing purebred parents from different breeds can have any combination of the parents' traits. Because both pugs and boxers have short coats and faces with wide foreheads, short muzzles and a marked break in the profile, pug/boxer puppies are likely to have these traits but may vary considerably in size. They are likely to be prone to the eye, dental and respiratory issues common to both breeds.
