Club Tijuana Xoloitzcuintles de Caliente, commonly known as Tijuana, or simply as Xolos, is a Mexican professional football club based in Tijuana, Baja California, Mexico. The club's badge is the founder's hairless xoloitzcuintle, Hermoso.

The Xoloitzcuintle is one of several breeds of hairless dog. It is found in standard, intermediate, and miniature sizes. The Xolo also comes in a coated variety, totally covered in fur. Coated and hairless can be born in the same litter as a result of the same combination of genes. The hairless variant is known as the Perro pelón mexicano or Mexican hairless dog. It is characterized by its wrinkles and dental abnormalities, along with a primitive temper. In Nahuatl, from which its name originates, it is xōlōitzcuintli (singular) and xōlōitzcuintin (plural). The name comes from the god Xolotl that, according to ancient narratives, is its creator and itzcuīntli, meaning 'dog' in the Nahuatl language.
