Miniature Chihuahua Health Problems

Small Chihuahuas are at risk for a number of health problems.

While the American Kennel Club does not recognize miniature or teacup Chihuahuas to be an official size within the breed, some are abnormally small. Small Chihuahuas are at a higher risk than larger dogs for a variety of health conditions, some of which can be life threatening.

Breeding

Bad breeding practices, such as inbreeding, can heighten the risk of small Chihuahuas developing certain health conditions, such as patellar luxation, where the patella slips out of place, then slips back. Patellar luxation can lead to breaks, bow-leggedness and other complications with age. A properly bred Chihuahua is less likely to develop certain health complications but should still be screened regularly.

Time Frame

Small Chihuahuas can develop certain conditions throughout their lifetime. Some conditions are apparent at birth, while others develop with age as a result of genetics or negligence. For example, the smaller the Chihuahua, the larger the risk of gum disease forming as they age. Because the teeth are overcrowded in the mouth, food particles get stuck between the teeth and rot, causing bacteria and cavities to form.

Mild Health Problems

There are several mild health problems that very small Chihuahuas may encounter. A collapsing trachea is very common in this breed, and often develops with age. The trachea of the Chihuahua flattens and causes the dog to cough dryly and have mild breathing problems temporarily.

Hypoglycemia, or low blood sugar is also very common in small Chihuahuas. Hypoglycemia can cause the dog to act lethargic and weak, but is easily treatable.

Severe Health Problems

There are several severe health problems that very small Chihuahuas are at risk of developing, all of which can be fatal if left untreated. Hemophilia is a blood disorder that makes it impossible for the dog's blood to clot on its own. This can be potentially deadly if the dog is ever injured.

Hydrocephalus is a condition that causes excessive spinal fluid to build up within the Chihuahua's skull, in turn putting pressure on the brain. Hydrocephalus can lead to seizures and vision problems for the chihuahua, as well as an enlarged skull.

A number of heart conditions are common in small Chihuahuas, including murmurs, mitral valve disease and pulmonic stenosis, all of which can be fatal if not appropriately treated.

Prevention/Solution

The easiest way to prevent your Chihuahua from developing any mild or severe health complications is to have him carefully and fully screened by a veterinarian. A series of blood tests, scans and physical examinations can result in an early diagnosis or assess the risk the dog faces. Regular teeth cleanings and checkups also can help prevent your Chihuahua from facing health problems as he ages.
