E tal como eu defendo, haverá mais pessoas que o defendem. E depois assisto à defesa da formação de uma raça que, à partida, trás alguns problemas associados à cor branca, já para não falar de albinismo.
Não gosto nada da raça, por alguns motivos que se prendem à cor, a começar por achar que um cão branco é fácilmente visto de noite por intrusos. E depois por outros aspectos, como a surdez, um cão de guarda surdo é daquelas coisas.
E raças, onde o branco é a cor, já existem imensas. Não havia grande interesse nessa raça, apenas um certo excentricíssimo, muito comum no meio.

A homozygous (or "double") merle is one with two copies of the merle gene, and this severely impairs its ability to make pigment, leaving large areas of the dog pigmentless (white). Pigment is actually necessary for certain parts of the body to function correctly, so lack of pigment can cause health problems.
Dogs with large amounts of white caused by the homozygous piebald allele (sp), such as Bull Terriers, Boxers and Dalmatians, can also have some of the same health problems as double merles, particularly deafness (which is a huge problem in Dalmatians).
Lack of pigment in particular parts of the inner ear can cause deafness, which can be unilateral (just one ear) or bilateral (both ears). It is commonly claimed that dogs with white ears are always deaf, but in fact it's been shown that whether or not pigment is visible on the outer ear does not affect whether or not the dog can hear. In other words, a dog may have coloured ears but still be deaf, and a dog with white ears will not necessarily have any problems.
The double merle gene can also cause eye deformities. This is because the location of the eye cells in an embryo happens to be the same place that pigment starts to appear. If there is a problem with the pigment, this can therefore affect the development of the eyes. Problems include irregularly-shaped pupils, subluxated pupils (not positioned in the right place), microphthalmia (abnormally small eyes, usually with impaired vision), and other, less visible abnormalities causing blindness and bad vision.
Lack of pigment anywhere on the dog can make the skin much more sensitive to the sun. This is a particular problem on the nose, as it is so exposed, but any area of pink skin is susceptible to sunburn and skin cancer. The same problem occurs with any animal which has little or no pigment. White cats are probably the most well-known example. Skin cancer rates in white cats are extremely high and a surprising proportion of cats with white ears end up having their eartips amputated to stop the spread of cancer. The main way to prevent sunburn in animals is the same as with humans - apply suncream!
