What does wool do to a chinese crested dog?

Wool is not recommended for Chinese Crested dogs. Chinese Crested dogs are a hairless breed, and their skin is very sensitive. Wool can cause irritation and even allergic reactions in Chinese Crested dogs. Additionally, wool does not provide any insulation for Chinese Crested dogs, as they do not have a thick undercoat. In cold weather, Chinese Crested dogs should be dressed in a warm dog sweater or coat.
