Jack Russell Terrier
The Jack Russell Terrier is a high-energy working terrier with endless enthusiasm.
Temperament
The Jack Russell Terrier is an energetic, clever, and athletic little dog with a big, fearless personality. They are highly intelligent and curious, which makes them fun but also quite stubborn and independent if not properly trained. Naturally vocal and alert, they make enthusiastic watchdogs and thrive in active homes where they receive plenty of mental and physical stimulation.
Health Considerations
Jack Russell Terriers are generally robust and long‑lived, with an average lifespan of 13–16 years when properly cared for. However, like all breeds, they can be prone to certain health issues, including patellar luxation (slipping kneecaps), Legg‑Calvé‑Perthes disease (a hip joint disorder), and inherited eye problems such as lens luxation and cataracts. Some individuals may also develop deafness, particularly in lines with a lot of white in the coat, and a small percentage may show allergies or skin sensitivities. Regular veterinary checkups, including eye and hearing evaluations as recommended, are important for early detection and management of potential issues. Keeping your Jack Russell at a healthy weight, providing appropriate exercise, and maintaining good dental care can help prevent many common problems associated with aging. Responsible breeders screen their breeding dogs for orthopedic and eye conditions, so choosing a reputable breeder or working closely with a trusted veterinarian and rescue organization is key to supporting your dog’s long‑term health.
