What Is the Lifespan of an American Bully XL?

The American Bully XL is known for its strength, loyalty, and family-friendly temperament. But one of the most important questions for owners is: How long do XL Bullies live?

On average, the lifespan of an American Bully XL is 10–12 years, but with proper care, some live much longer. In fact, there are documented cases of XL Bullies reaching 16–18 years of age when given the right diet and lifestyle.

Factors That Affect an XL Bully’s Lifespan

Several key elements play into how long your Bully will live:

• Diet – What your dog eats directly impacts their overall health and longevity.

• Exercise – Maintaining a healthy weight reduces stress on joints and the heart.

• Genetics – Responsible breeding lowers the risk of inherited conditions.

• Veterinary Care – Regular checkups help catch health issues early.

Why Diet Matters Most

One of the biggest influences on lifespan is what you feed your American Bully XL. Many owners make the mistake of relying only on dry kibble, but overprocessed foods and artificial treats can shorten a dog’s life.

Raw Feeding and Natural Nutrition

In the wild, canines eat a raw, natural diet—meat, bones, and organs. This diet is biologically appropriate and provides nutrients in their most natural form. Owners who feed a properly balanced raw diet often report longer life spans, healthier coats, and stronger immune systems.

Some Bully owners have seen their dogs live up to 18 years on a raw diet—far exceeding the average expectancy.

Foods and Treats to Avoid

Certain processed foods and treats are harmful and can contribute to serious health problems, including cancer. Avoid giving your XL Bully:

• Overprocessed kibble as the main diet

• Milk bones and cheap biscuits (often full of chemicals and fillers)

• Pig ears and rawhides (can cause blockages and digestive issues)

• Plastic or artificial treats (linked to long-term health problems)

Final Thoughts

So, what is the lifespan of an American Bully XL? While the average is 10–12 years, the truth is that with the right nutrition and care, many Bullies can live far longer. A natural, raw-based diet, combined with exercise and proper care, may help your XL Bully thrive well into their mid-to-late teens.

Your Bully’s lifespan isn’t just genetics — it’s in your hands.
