What are the common health problems in Chihuahuas?

Some conditions are more common in Chihuahuas due to their genetics and small size. Here are the most frequent illnesses you should be aware of.
DENTAL PROBLEMS
Why is my Chihuahua so vulnerable to dental problems?
Their small jaw size and the number of teeth it contains make them extremely vulnerable to plaque and tartar buildup.
According to Dr. Sandra Manfra Marretta, professor emeritus and former head of the small animal dentistry service at the University of Illinois, "periodontal disease is the most frequent and most diagnosed health problem in small pets." She adds that "miniature dogs, like the Chihuahua, have a very high incidence of developing a severe form of this disease."
A study showed that more than 80% of dogs show signs of dental disease before the age of 3, and this percentage is particularly high in miniature breeds. Without preventive care, periodontal disease can lead to infections, pain, and even problems in the liver, kidneys, or heart.
PATELLAR LUXATION
Is patellar luxation a hereditary disease?
Yes, it is one of the most common hereditary conditions in Chihuahuas. It occurs when the kneecap shifts from its normal position, causing pain, occasional lameness, and difficulty jumping. A breed study showed a 23% prevalence in the population studied, making it a common and genetic orthopedic problem.
HYDROCEPHALUS
Is hydrocephalus common in Chihuahuas?
Hydrocephalus, often called "water on the brain," is a genetic condition that causes cerebrospinal fluid buildup in the skull. Chihuahuas are among the breeds most predisposed to this condition, which can cause neurological problems, seizures, or abnormal head enlargement.
TRACHEAL COLLAPSE
Is my Chihuahua more at risk of tracheal collapse?
Tracheal collapse is a very common genetic respiratory condition in very small breeds. The trachea, made of cartilage rings, can collapse, making breathing difficult and causing a dry cough, often described as a "goose honk." A harness is recommended for walks to avoid putting pressure on the neck, which can worsen this condition.
How to take care of your Chihuahua’s health daily?

Prevention and daily care are the best ways to minimize risks. Here are our tips for a healthy Chihuahua:
- Brushing teeth: Get your dog used to brushing from a young age.
- Weight control: Obesity can worsen patellar luxation and other joint problems.
- Using a harness: Always choose a harness instead of a collar for walks to protect their fragile trachea.
- Proper nutrition: Provide high-quality, balanced food adapted to their size.
- Regular monitoring: Pay attention to changes in behavior, gait, or appetite, as early detection is key.
