This breed has a higher risk of health issues

Bullmastiffs are a brachycephalic breed; problems associated with the condition include;
Brachycephalic obstructive airway syndrome: a condition in brachycephalic breeds (those with a short nose and squashed face) where breathing is obstructed and can lead to reduced ability to exercise, or even severe respiratory distress.
Skin inflammation/infection: brachycephalic breeds have a short nose and a normal amount of facial tissue. This means there is often excess skin around their face which leads to skin folds. The skin inside these folds can become sore and infections are prone to develop. 
Eye ulcers: ulcers are painful erosions on the surface of the eye. They are more common in brachycephalic breeds due to their conformation, as their eyes tend to be more bulbous.

They can also suffer from:
- Hip dysplasia 
- Elbow dysplasia
- Cruciate problems 
- Gastric dilatation volvulus
- Panosteitis 
 - Dilated cardiomyopathy¹ which is a condition where the heart muscle becomes progressively weak and cannot beat properly.
- Wobblers syndrome² which is a problem in the spine that causes a wobbly abnormal gait.
- Entropion³ and/or ectropion which are painful conditions where the eyelids turn inwards or outwards, this happens as a result of excessive skin around the eyes.
- Cherry eye4, which is where a gland within the third eyelid pops up in the corner of the eye.

Personality

Despite their often violent past, the Mastiff is a calm, gentle and noble dog that is devoted and loving towards their family - often thinking of themselves as a lap dog! They are however indifferent or even suspicious of strangers - human or canine.
