Chihuahua Breed Information

Though the exact origin of the Chihuahua breed is still unknown, there are two theories that throw some light on its history. One of the most plausible theories is that, they are a descendant of a round headed, small-framed South American dogs known as Techichi, which were found during the Toltec civilization. According to other beliefs, the small, hairless Chinese Crested dogs were brought to Mexico and then bred with native Mexican dogs. Regardless of which speculation is right, modern day Chihuahuas were found in the Mexican state, Chihuahua, around 1850.
With terrier-like qualities, Chihuahuas are highly alert in nature. Chihuahuas make very good companion dogs as they bond strong with their owner and family members. These tiny dogs are sensitive and only demand affection from their owner. You can expect the Chihuahuas to be a little reserved in the beginning, but they respond well to training, which inculcates love, care and positive reinforcement.

Health and Care
These cute dogs though highly active, are prone to several diseases that can take a toll on their life, if not diagnosed on time. Chihuahuas are prone to neurological and genetic problems, such as epilepsy and seizures. Like other toy breeds, Chihuahuas are also prone to hydrocephalus, a painful disease that causes enlargement of head. Hydrocephalus can be diagnosed with a proper CT scan. Hypoglycemia, or low blood sugar, is another common problem of these toy puppies. If not diagnosed earlier with the help of fasting blood glucose/insulin test and ACTH stimulation test, it can lead to coma and death. Regular brushing of fur and proper dental care is very important to avoid infections. Over-feeding and insufficient exercise can increase risk of tracheal collapse, joint injuries, and shortened life span.
