Chihuahuas are tiny friends with huge hearts and delightful, often feisty personalities. They are quick on their feet and alert, their large ears eyes ready to focus on whatever intrigues them. Their coats can be long or short and a wide variety of colors. Their history is mysterious but some of the earliest specimens were found in the Mexican state of Chihuahua, from which their name is taken, and over the years they have been used in religious ceremonies and kept as pets by the upper class. They make good family pets and are good with gentle children who have been taught to use proper manners around pets. Because of their size they do have extensive exercise needs and do well as city pets. Smooth coated Chihuahuas need very little grooming but can be sensitive to cold temperatures. Those with long hair do fine with occasional brushing and minimal grooming.
