Overall The Chihuahua breed is relatively healthy. They live the longest of all the dog breeds and often make it into their twenties!
But like all dog breeds, there are some common genetic health issues in Chihuahuas that you need to be aware of.
It’s not hard to imagine why Chihuahuas may have eye problems with their large protruding eyes. Their eyes can easily get injured or get infected.
Dry eyes or Keratoconjunctivitis Sicca is another eye issue.
You may also notice tear staining under your dog’s eyes. This is normal unless you notice an odor. An odor is a sign of infection which needs to be treated by your veterinarian.

You have probably heard of this condition before since some people suffer from it. What it is, is low blood sugar. It is most common in younger Chihuahuas and Chihuahua puppies. Basically it’s caused by the high metabolism of the young dog. It’s important to make sure your Chi eats at regular intervals. Symptoms include muscle weakness, staggering, listlessness and in extreme cases, seizures, coma and death. If you suspect your dog is suffering from this, rub a little honey or jelly on his gums and see if that helps. You can read more about it here: Hypoglycemia in Chihuahuas.

Chihuahuas tend to shiver a lot. It can be caused by several different things. The most common reason is because they are cold. Being that their breed comes from a hot climate, they have trouble dealing with chilly temperatures.
Chihuahuas also shiver when they are stressed, excited or frightened.
Hypoglycemia can cause shivering too.

Chihuahuas have very small mouths, which often causes dental problems with overcrowding with their teeth. The overcrowding causes food build up in their teeth which causes decay and tooth loss.
In this condition, the dog’s windpipe weakens and collapses, causing the dog to chronically cough and wheeze. It can be quite serious. You can read more about it here Tracheal Collapse
