Cancer – Just like humans, cancer can develop in dogs as well. Bullmastiff is prone to lymphosarcoma, osteosarcoma, hemangiosarcoma, and mast cell tumors.

Bloat – This is a life-threatening medical condition that is prone to large deep-chested dogs like English Bulldog Mastiff mix. Dog parents must be aware of this so they know what is needed if an unfortunate situation happens.

This is a condition when the stomach of the dog is distended with gas or air and then twists. The dog is not able to vomit the extra air and goes in shock due to the lowering of blood pressure. Immediate medical intervention is required.

Care must be taken not to give one large meal and instead divide it into two or three meals in a day. Be vigilant that the dog is not eating rapidly. Do not give large volumes of water to drink after eating.

Exercise just after eating should also be avoided. Feeding on a raised platform is best so the dog doesn’t need to try bending down to eat. 

Hip Dysplasia – This is a medical condition which a dog can inherit. In this, the thigh bone doesn’t fit properly into the hip joints.

This is painful for dogs in varying degrees. It can sometimes get unnoticed until arthritis develops in old age. Dogs with hip dysplasia should be neutered as this can be passed onto dogs’ offspring.

Aortic Stenosis – This is also an inheritable medical condition in which the defect in the aorta narrows the aortic valve to enable a smooth blood supply.

Symptoms include dog feeling lethargic all the time and having instances of fainting. Again, as this is an inheritable condition, dogs having this should not be bred.
