Owners of the Chi Staffy Bull say they are an affectionate dog and are loving toward their people from just a few weeks of age. Care does, however, need to be taken that your dog has a chance to interact with all family members as the Chihuahua parent can become a one-man dog. The Chi Staffy Bully is alert, brave, and curious, but he can be stubborn as well. He is an excellent guardian but must be taught appropriate behaviour when guarding isn't needed. Many experts encourage obedience classes for the sometimes tenacious Chi Staffy Bull so that he can learn to get along with everyone, gain confidence if he is shy, and use his intellect.

While there is not much information on the Chi Staffy Bull breed itself, one can still learn much about the breed by studying the parent breeds. The ancestors of the Staffordshire Bull Terrier are thought to include the Bulldog and the Mastiff. The Staffordshire Bull Terrier originated in the early nineteenth century and was created as a smaller, faster fighting dog (when compared with the Bulldog). Ironically, the Staffordshire was bred to be friendly with people. Most experts believe the Staffordshire of today is a mix of the Manchester Terrier and the Bulldog. The Staffordshire Bull Terrier is generally a family companion, smaller than an American Pit Bull Terrier, and a good watchdog, but not highly aggressive.

Named after the Mexican state of Chihuahua, ancient paintings show that the Chihuahua was highly prized by the Toltecs as far back as the 9th century. His ancestor was the Techchichi dog who was thought to have magical healing abilities and was also cremated and buried with his owners when they passed on to the next world.
