are sometimes not easily identified. A dog may begin with the stages of heart failure which can include coughing, sluggishness, and breathing difficulties. It is important that Chihuahua owners not let their dogs become overweight as this causes excessive stress on the heart. Treatment for heart disease will depend upon the underlying problems that may be causing the disease. Owners should discuss treatment options with their veterinarian.

Some dog breeds including Chihuahuas may incur mitral valve disease which is commonly associated with a heart murmur. This illness can be quite serious as it is caused by irregular functioning of the valve that separates chambers of the left side of the heart. Veterinarians generally treat this disease with medications that are designed to reduce the symptoms caused by the illness.

Hydrocephalus

Hydrocephalus is associated with infections of the brain, tumors, and head injuries but its most common cause is a hereditary defect. When cerebrospinal fluid accumulates in the skull, pressure increases on the brain and the tissues inside the brain are forced against the skull. This disease is seen most often in toy breeds such as Chihuahuas and Toy Poodles. Treatment mainly depends upon the early diagnosis and the severity of the condition which can include surgery.

Environmental factors can adversely affect the health of a Chihuahua. Some can go their entire life without significant complications while others may encounter serious health issues. Any dog breed that is not provided proper nutrition and care is at risk to health-related problems and injuries. If your Chihuahua exhibits signs of illness, you should seek veterinary care for your pet.
