All puppies should be checked for deafness, as this sometimes occurs (most commonly in pure white dogs) and is difficult to notice, especially in a relatively young puppy. Many Bull Terriers have a tendency to develop skin allergies. Insect bites, such as fleas, and sometimes mosquitoes and mites, can produce a generalized allergic response of hives, rash, and itching. This condition can be stopped by keeping the dog free of contact from these insects, but this is definitely a consideration in climates or circumstances where exposure to these insects is inevitable. Their lifespan is somewhere between 10 and 14 years, although they can live longer - the oldest female Bull Terrier on record being an Australian housepet dubbed "Puppa Trout" who remained sprightly into her 17th year.The Bull Terrier's coat is easy to maintain, but grooming can keep it in near-perfect condition. Adding oils to their meals can also vastly improve the quality of their coat. The Bull Terrier requires a fair amount of exercise, but overworking the dog at a young age will cause strained muscles. Older dogs do require exercise, but in small doses, whereas younger ones will be happy to play for hours on end. The breed is renowned for being extremely greedy; be sure to maintain a good balance of exercise and food, or the dog can become overweight. Also, be sure to check ears, eyes, nose and mouth every day for signs of infection.

Common Ailments: Deafness, Umbilical Hernia and Acne. Bull Terriers can also suffer from Obsessive complusive behavior, such as tail chasing, self mutilation, and obsessive licking.
