Why Their Large Size Can Be A Contributing Factor
To The Mastiff’s Short Lifespan

Firstly, it is noticeable that smaller dog breeds tend to live much longer than larger breeds such as Mastiffs, Bernese Mountain Dogs, and Irish Wolfhound. This has inspired a number of studies, such as the ones conducted in 2005, 2013, and 2016, that have eventually linked the size and lifespan of dogs. 

The findings of these studies are:

• Large dogs grow quicker, and this affects their immune system and increases the number of free radicals in their bodies.

A smaller dog such as a Cocker Spaniel will reach maturity within two years when he weights around 14kg. In the same amount of time, a Mastiff will grow to weigh around 80kg. This rapid growth has seen to affect the output of the thymus, the gland primarily responsible for the health of the immune system.

• There is a clear link between size and aging rate

While the reasons for this are not yet clear, it has been seen that, within the same species, larger individuals age faster than smaller individuals.

What Health Conditions Affect The Lifespan of Mastiffs?

Similarly to other breeds, Mastiffs are predisposed to many health disorders and conditions that considerably lower their life expectancy. Here are the ones you should be looking out for:

• Hip Dysplasia and Elbow Dysplasia: these are two similar conditions that often originate from abnormal development. The large size and rapid growth of Mastiffs make them particularly prone to it. This condition refers to the loosening of the hip or elbow joints. This can cause pain, difficulty of movement, and even instability.
  
• Arthritis: This condition is caused by the inflammation and stiffening of joints. It can be incredibly painful for your Mastiff and, once the joints have been damaged, there is yet no cure available.
• Wobbler Syndrome: Particularly common in large and giant breed dogs, this neurologic disease affects the neck region of the spine. It can cause neurologic disability and can be treated through anti-inflammatory drugs or surgically.
• Dilated Cardiomyopathy: This is one of the most common cardiovascular diseases contracted by Mastiffs. It happens when the heart is not strong enough to pump adequate blood through the body. While the development of this disease is slow, it can be lethal for the patient.
• Hypothyroidism: This condition is usually caused by an inflammation of the thyroid gland, which is responsible for controlling many body functions. If not treated promptly, it can lead to more serious health conditions.
• Bloat (GDV or Gastric Torsion): This disorder is one of the most common causes of death for Mastiffs. It happens when the stomach fills with air, twists on itself, and prevents blood and oxygen from circulating through the body. This is a medical emergency and, if not treated immediately, can lead to death in a matter of hours. 
  
  

Tips to Help Your Mastiff Live Healthier For Longer

While some genetic factors cannot be fought, there are some preventive measures that you could take to try to improve the lifespan of your Mastiff. 

• Exercise: exercise is incredibly important during the life of your Mastiff. In fact, without physical stimulation, your dog won’t be able to strengthen its muscle legs, a vital factor if he or she is affected by a bone or joint condition later on in life. During your Mastiff’s development phase, introducing just the right amount and type of exercise is essential. In fact, jumping, running, and demanding exercise can lead to future health conditions. On the other hand, a lack of stimuli can lead to obesity. Read Here our article about the Mastiffs exercise needs.

• Nutrition: since your puppy will be growing incredibly fast during his first years, nutrition is one of the most important factors for your dog to live a healthy life. Speak to your vet to find out a nutrient and balanced eating plan for your Mastiff. To lower the likelihood of Bloat, avoid feeding your Mastiff only once a day. This page on our site will tell you what you need to know about feeding your puppy thru out it's puppyhood. 

• Socialization: socialization can help your Mastiff release accumulated energy and stress, which can be incredibly detrimental for its health. At the same time, by letting your Mastiff socialize and free play, you will avoid the destructive behavior that can cause damage within your household. Learn some great socialization techniques from this page on our site.

• Keep yourself informed: many of the conditions that develop towards being life-threatening for your Mastiff have clear medical signs. As an owner, it is your responsibility to be aware of them to be able to start medical treatment immediately and save your dog’s life.
