There are two different types of Chihuahuas: the smooth coat Chihuahua and the long coat Chihuahua. These two types come in a variety of colors including black, fawn, white, gray, silver and chocolate as well as color combinations such as blue with white or tan markings.
The Chihuahua, regardless of coat, is an easy dog when it comes to grooming and only needs a weekly brushing to stay clean. The dogs do shed throughout the year, however, and are not necessarily the best choice for someone with allergies. The Chihuahua weighs between 3 and 6 pounds so it is best for families with young children to choose a sturdier, larger dog because the small size of the Chihuahua makes it prone to injury when young children are rough.
The Chihuahua has a vibrant and strong personality. It regards itself as an alert watchdog and will pay attention to everything around it. To help the Chihuahua avoid incessant barking and nagging, it is best to socialize the dog right away as a puppy. A well socialized Chihuahua will be much friendlier to strangers. The Chihuahua is slated to live between 10 and 18 years so it is important for new owners to recognize that adopting a Chihuahua is a serious and lengthy commitment.
