A dog is ineligible to compete in regular dog shows. A purebred dog that is ineligible can still compete in other types of shows, such as agility and obedience. In other words, a disqualification does not necessarily mean that the dog is not a purebred, just that it is not eligible to compete in regular dog shows. A dog that fails to qualify must be a purebred dog. This is because each dog has its own standard, and usually the last item in the standard lists the specifics of defects and disqualifications. Therefore, only a purebred dog with a strict standard can have a widely recognized disqualifying condition. Therefore, the specific disqualifications vary for each dog depending on the breed standard.
