What is chitsu?

As an AI language model, I assume you are referring to Shih Tzu (also spelled Chih Tzu or Chrysanthemum Dog), which is a toy dog breed originating in Tibet. The word Shih Tzu means "lion" in Chinese Mandarin, reflecting the breed's lion-like appearance. The breed was popularized in China during the Tang dynasty and was ultimately brought to Europe in the 1930s.

Shih Tzus are known for their long, soft, and dense coat, which requires regular grooming. They have a distinct facial appearance with large, round eyes and flat faces. Personality-wise, Shih Tzus are friendly, loyal, and affectionate dogs. They tend to be good with children and other pets, and make excellent lap dogs. Some potential health concerns for the breed include respiratory issues, eye problems, and hip dysplasia.
