The average lifespan of a Bull Terrier is around 13 years. Factors that can influence their longevity include genetics, diet, exercise, and regular veterinary care. Health issues such as congenital sensorineural deafness and heart and renal problems are known to affect this breed, and managing these conditions effectively is crucial. Ensuring a Bull Terrier receives a balanced diet, adequate exercise, and preventive health care, along with regular check-ups, can significantly contribute to a longer and healthier life. Engaging them in mental stimulation and maintaining their social interactions are also beneficial.
