History of the Chihuahua
The Chihuahua's history is an extremely long and intriguing one. These dogs are a very ancient breed. Chihuahua ancestry is said to have descended from the Techichi, a larger dog that was around during the Mayan civilization. According to engravings on pottery dated to 300 BC, Techichis were believed to have been around at that time.

Chihuahua Care
The Chihuahua's affectionate and attention-loving nature makes them an ideal candidate for a snuggly dog that enjoys being carried around and pampered. When raised and handled appropriately, the Chihuahua can make an excellent companion for a wide variety of families. It should be noted that not all Chihuahuas will automatically get along with children. However, they can be trained and socialized to get along with kids.
Exercise
It is often overlooked that smaller dogs require more exercise than their larger counterparts. Regular exercise is essential for Chihuahuas. Chihuahuas have a moderate to high energy level and may develop behavioral problems if not given sufficient exercise. Regular exercise and mental stimulation will help to maintain your dog's mental and physical health, while also benefiting you. It is important to remember that overzealous exercise can be detrimental to your dog's health. If they seem tired or overexerted, it is advisable to pick them up and head home.
Grooming
It should be noted that the two coat varieties of the Chihuahua have slightly different grooming needs. The smooth-coat Chihuahua requires only occasional brushing and regular baths to maintain a dapper appearance. In contrast, the long-haired variety should have its coat brushed at least once a week to avoid tangles or mats. It is advisable that both varieties have their nails trimmed regularly. It is important to maintain good dental care for your dog. This includes brushing your dog's teeth and following any recommendations from your vet regarding dental treats. It is important to check the ears of a Chihuahua regularly and remove any excess wax or debris to avoid the risk of ear infections.
Training
Due to their tendency to adopt a sassy attitude, Chihuahuas require proper socialization and positive reinforcement-based training. Without adequate socialization, the breed may become fearful and defensive, especially around new people or animals. While the breed may be somewhat stubborn at times, it is also intelligent and can become well-behaved with dedication and consistency. It is also important to teach your Chihuahua to tolerate being handled from an early age, particularly for procedures such as nail trims and grooming.
Nutrition
A premium dog food formulated for the specific age of the dog (puppy, adult, or senior) will contain all the nutrients required by the breed. Some Chihuahuas are prone to becoming overweight, so it is important to monitor your dog's calorie intake and weight. While treats can be an effective training aid, overconsumption can lead to obesity. It is advisable to limit the amount of table scraps given, particularly those containing cooked bones or high fat content. It is important to be aware of which human foods are safe for dogs and which are not. Should you have any concerns about your dog's weight or diet, we advise you to consult with your vet.
Health Problems
Chihuahuas are prone to some genetic health conditions, including:
Patellar Luxation: This is a dislocating kneecap, which causes the dog pain. It is possible that you may observe your dog holding its foot off the ground, and that the kneecap may pop back into place when the muscles relax and lengthen.
Collapsing Trachea: This is a restriction of the windpipe that is often seen in small dogs. Coughing when pressure is put on the trachea is a sign of this condition. If you notice these symptoms, please discuss them with your veterinarian.
Hydrocephalus: This condition is characterized by an abnormally large head and the accumulation of fluid.
Hypoglycemia: Low blood sugar can affect Chihuahua puppies, and they may need a sugar supplement.
