This breed can be somewhat difficult to train. Health Problems Bull Terriers are generally healthy, but some are prone to suffer from a zinc deficiency, which can cause death. Some pups are born deaf. Some suffer from obsessive compulsive behaviors, such as tail chasing. Some male Bull Terriers have an overabundance of testosterone, which makes them too territorial.
Neutering often fixes the problem - mellowing the dog out some.
Can be sensitive to fleas or other parasites. Living Conditions Bull Terriers will do okay in an apartment if they are sufficiently exercised. They are fairly active indoors and a small yard will do. They prefer warm climates. This breed needs vigorous daily exercise, but they should always be on a lead in public at all times, because they will fight with other dogs.
