Pet Care Rx explains that an albino Chihuahua dog has some of the common characteristics of normal Chihuahuas, but its albino nature means that it has pink eyelids, a pink nose, a white coat, pale skin and eyes that are either blue or red. The condition is caused by an extremely rare genetic mutation.
The Chihuahua Club of America, Inc., explains that a dog must meet certain breed standards to be considered a purebred Chihuahua. The dog must usually be 6 pounds or lighter, have a rounded "apple dome" head shape, pointed ears that are erect, a tail that is held high and a long, slim body.
Some dogs have varying degrees of albinism. Pet Care Rx explains that it is much more common for a dog to have some characteristics of albinism, such as a white coat and pale skin, than to have all of the condition's features. Albinism disrupts the production of melanin, which is what gives color pigmentation to eyes, skin and hair. Albino dogs do not have white coats. Instead, they have coats that are completely devoid of color.
Albino Chihuahuas can experience other complications from the condition, including deafness. Many albino dogs are deaf because the unpigmented skin in the ear canal causes nerves in the ears to degenerate.
