All Chinese Crested dogs are heterozygotes, not homozygotes. In other words, they have a normal gene and a hairless gene. In fact, if two hairless dogs mate, only half of their offspring will be hairless because of this normal gene. One in four pups will have a normal coat. But a quarter of dogs – dogs that inherit hairless genes from both parents – die in the womb. This is because mutations in the same gene that prevent normal hair follicle development can also lead to abnormal formation of the head and other important organs. (if only the gene inherited from one of the parents mutated, it would never happen – in this case, you would only get hairless.) “It’s not clear exactly why dogs with parental mutations can’t survive,” Dr. Ferrer said, “but we know there are many aspects to it.” Buy a Chinese Crested dog.

Special nursing of Chinese crested dogs

Why do Chinese Crested dogs have no hair? One is to avoid sun exposure. Hair protects skin. For hairless dogs, exposure to sunlight can cause skin inflammation, leading to infection and, in the long run, squamous cell carcinoma. White dogs of any breed are also prone to skin cancer in areas with less hair than other parts of the body, such as the head and abdomen. But a hairless dog can take it to any part of its body because it is exposed. And the risk is greater, if not surgically removed, squamous cell carcinoma will prove fatal over time. People understand that. It grows very slowly and will not spread, but it must be removed so as not to cause fatal consequences. Of course, you can’t keep your Chinese Crested dogs (or any other dog) in the sun 100% of the time. But at least make sure Chinese Crested dogs stay indoors at the time of the day when the sun is strongest.
