Musculoskeletal conditions:

Patellar luxation is an hereditary disorder affecting the knees of the dog. The kneecap slips off the groove where it sits and you may notice your dog running while holding his hind leg in the air. It can sometimes slip back in place and then you see your dog running in his usual way. It becomes more serious when it affects both legs.

Many people find giant dogs irresistible because they're usually gentle, patient and loving. However, it is their very size which makes them more prone to certain health concerns and gives them a shorter lifespan.

It is why it is so important to ensure you feed your pet a healthy diet to ward off illness. A large dog like the Irish Mastiff doesn't have a particularly long lifespan, and with good care he can get to 9, 10, 11, 12 years of age.

Hip Dysplasia:

This condition is more common in large dogs and it can lead to joint degeneration, arthritis and pain. Your pet may even be reluctant to get up and greet you when you come home which can be very sad. Vet intervention will certainly be required.

Dilated Cardiomyopathy:

This heart disease is commonly seen in large dog breeds where the heart becomes weak so that it can't pump blood throughout the body. Coughing, difficulty with breathing, weakness and lethargy are just some of the symptoms of this disease and will also require veterinary intervention.

Exercise:

Grooming:

Diet:
