There are also theories that they have discovered in Mexico in the late 1800s. It is possible that chihuahua is a descendant of the techichi, a small framed companion dog that was domesticated by several pre-Columbian Mesoamerican civilizations and native North American tribes.

Chihuahua is comical and entertaining, expressive loyal little dogs. They would burrow under blankets and dance on their hind legs and lick everything in sight. They are absolutely brimming with personality, and often are quirky and eccentric.

It is said that how a chihuahua turns out depends on the genetic temperament of his lineage.


The dog’s lifespan is one of the longest in the canine kingdom. They can reach mostly from 17 to 20 years. However, chihuahuas are still like another breed of dogs and are prone to several health conditions:


The small size of the dog can lead to physical injury if not properly watched or prevented. There are a lot of cases in which the dog is hurt fatally, they can easily be stepped upon, crushed by feet, run over by a car and even dropped from a high distance.

Dental problems

Chihuahua tends to have tooth and gum diseases. Understandably, this is because their mouths are small. Their teeth are overcrowded, making it easy for them to have dental problems. There are a lot of cases where the remains of the food were trapped between the teeth. This causes plaque and tartar buildup. Some dog teeth cleaning wipes can be used in such cases for removing the trapped food from teeth. If untreated, it can result in periodontal diseases such as gingivitis and periodontitis as well as premature tooth loss.


It is a state of abnormally low blood sugar. This is one of the most common problems that chihuahua has. This can result to cause problems to the nervous system, resulting in seizures and even coma.

A hypoglycemic attack can happen without any previous trigger. Sometimes, the dog may show lethargy, weakness, restlessness, and tremors as a sign of low blood sugar level.

If there is a hypoglycemic attack, you should take quick actions. This is because it can deteriorate quickly and can result in permanent brain damage.

Tracheal collapse

The windpipe is made up of rings of cartilage. Tracheal collapse occurs because the tracheal rings do not possess normal rigidity. When the dog inhales, it resulted in the trachea collapsing and narrowing the windpipe.

The typical sign of the problem is a goose honk cough, sometimes with gagging and harsh breathing. The symptoms can be made worse by stress and overexertion.

Consult your veterinary for further medication, although bronchodilator drugs are often used to treat mild to moderate symptoms.

Chronic Valvular disease

This is a heart disease in which the dogs have degenerative changes in their heart valves. Specifically, the leaflets of the valves grow thick and the shape becomes distorted. The hallmark symptoms of chronic valvular disease is a loud heart murmur that can be heard over the left side of the chest.

Luxating Patella

It is a leg problem that often occurs among chihuahua. It is basically a congenital disease in which the alignment of the bones and joints of the hind leg is abnormal. This results in a displacement of the patella to the side of the join.

The main sigh of this sickness is an intermittent hopping on the limb when the patella pops out of the place. To cure this problem, your dog might need surgical correction.


So the next question that you have in your mind would be, how to keep your dog away from all those health problems? It is easy. Firstly, you need to provide them with a healthy diet.

Chihuahuas Care

Chihuahuas are usually picky eaters and it is common for them to beg for human food. These food actually are not good for their health. So, avoid giving them your food.

Chihuahua is also a breed that loves to play and go for walks. Keep them healthy by taking them for an exercise. Just because they are small does not mean that they should be carried around 24/7.
