Traits at a glance
Scores are the AKC's 1–5 breed trait ratings. [1]
Exercise needs
The Chihuahua loves to run and play and can usually get enough exercise in a very small space. Simply trotting around following their people is usually enough exercise for this happy breed. Short, slow walks will keep your dog in good weight and condition. [1]
Grooming
The two coat varieties of the Chihuahua have slightly different grooming needs. The smooth-coat Chihuahua will need only occasional brushing and regular baths to look dapper, while the longhaired variety should have his coat brushed at least once a week to avoid any tangles or mats. Both varieties should have their nails trimmed regularly. [1]
Health issues to budget for
The majority of Chihuahuas are healthy little dogs, but there are some genetic issues that can affect the breed. You should choose your dog from a breeder who routinely does genetic health screenings on all breeding stock to ensure that the puppies they produce are as genetically sound as possible. Some of the issues that can possibly affect the Chihuahua include potential heart problems (patent ductus arteriosus, mitral valve disease), eye disease, and patellar luxation (loose kneecaps). Idiopathic epilepsy is also known to occur in the breed. [1]
AKC-recommended health tests for breeding dogs: Patella Evaluation, Cardiac Exam, Ophthalmologist Evaluation. [1]
