Candidate passages:
Boxers with white markings covering more than one-third of their coat – conventionally called "white" Boxers – are neither albino nor rare; approximately 20–25% of all Boxers born are white.
Genetically, these dogs are either fawn or brindle, with excessive white markings overlying the base coat color.
Like fair-skinned humans, white Boxers have a higher risk of sunburn and associated skin cancers than colored Boxers.
The extreme piebald gene, which is responsible for white markings in Boxers, is linked to congenital sensorineural deafness in dogs.
It is estimated that about 18% of white Boxers are deaf in one or both ears, though Boxer rescue organizations see about double that number.
In the past, breeders often euthanized white puppies at birth; today, most breeders place white puppies in pet homes with spay/neuter agreements.
White Boxers are disqualified from conformation showing by the breed standard, although in 2010, the German Boxer Club opened up an exhibition-only conformation class for white Boxers.
They are prohibited from breeding by every national Boxer club in the world, but can compete in non-conformation events such as obedience and agility, and like their colored counterparts do quite well as service and therapy dogs.

 : Won the Rookie King the year after Ippo.
A southpaw.
Sparred against Ippo before going on to face Sendou in what was Sendo's second title defense.
Shigeta fights like a left-handed boxer, which disrupts most boxers because of the lack of left-handed boxers.
In reality he is a right-handed boxer, which causes his attacks to be much stronger than they seem (since left-handed boxers tend to fight with the right hand in the front contrary to what right-handed boxers do.)
He was destroyed by Sendou, who demonstrated a startling new speed and sas forced to retire after the title bout, since the sheer brutality of Sendou's power left him traumatized.  
Legendary Champions is a 1968 documentary film written and directed by Harry Chapin featuring old boxers in action.
There are many scenes that show the boxers outside the ring, including some that are the only ones of their kind.
Several early boxers, John L. Sullivan for example, are shown in the only film ever taken of them.
The film of the Dempsey-Willard fight is very violent.
The documentary includes as history of Jack Johnson out of the ring.
The narrator incorrectly states that Jack Johnson is seen picking a defeated boxer's teeth out of one of his gloves.
The attire worn by some of the early boxers is more revealing than what modern-day boxers use, and to the other extreme, tights were even worn by some boxers.
The film was nominated for an Academy Award for Best Documentary Feature.
