Health Information
While generally recognized as a very healthy and long-lived breed, there are several health issues that you should be aware of when purchasing a Toy Fox Terrier.
Health Testing Guidance
Reputable breeders should be open about their breeding stock and share what they know about the breed's health. While no one can guarantee against unforeseen imperfections, being knowledgeable and asking questions will help you find the healthiest puppy possible.
Always ask to see the results of health tests (such as DNA tests for PLL and SCA, and OFA evaluations for patellas) for both parents of a litter.
Common Conditions
Patella Luxation
A dislocation of the kneecap that can be congenital. It is graded from 1 to 4 based on severity. All dogs should be screened prior to being bred to ensure joint health.
Demodectic Mange
Caused by microscopic mites often brought on by stress in puppies or young dogs. Most will 'self cure' as their immune system matures, but some may require treatment.
von Willebrand's Disease (vWD)
A genetic bleeding disorder making animals more likely to bleed abnormally. DNA testing is available, and carriers should be tested and bred responsibly.
Primary Lens Luxation (PLL)
An inherited condition where the lens of the eye becomes dislocated. DNA testing is crucial to avoid breeding two carriers together.
Spinocerebellar Ataxia (SCA)
A neurological disorder affecting balance and coordination. Genetic testing is available to identify carriers and prevent the disease in offspring.
Hypothyroidism
A condition where the thyroid gland does not produce enough hormones. It can be managed with daily medication.
