Health of the Chihuahua

This is a long-lived breed, often achieving 16 or more years of age. However, there are some genetic diseases that can cause problems. Like most toy breeds, the Chihuahua is susceptible to slipped stifles (a knee injury caused by joint weakness) and fractures and may suffer from jawbone disorders, eye problems, heart disease, and tooth and gum complaints. The potential for some of these problems can be minimized by buying from a breeder who tests breeding stock for inheritable problems and by careful management. For example, Chihuahuas should not be allowed to jump off high furniture or out of your arms as the impact on landing could fracture a leg. Children should not be allowed to carry a Chihuahua or to play roughly with one for the same reason.

The Chihuahua puppies is also born with a soft spot on the top of his head that may not fully close, so a blow here could kill him.

The Chihuahua tendency to shiver or tremble is not a health issue but takes place when the dog is excited or stressed. One explanation is the toy dogs have a higher metabolism and so dissipate body heat faster than larger dogs. Shivering helps to generate body heat – that’s why people shiver when we are cold. However, rapid dissipation of body heat is a distinct disadvantage in cool or cold climates, so Chihuahuas should always be protected when taken outdoors in these areas. Fortunately, there are dozens of styles of protective sweaters available.
