Frequently Asked Questions
Why do English Mastiffs have such short lifespans?
Giant breeds have shorter lifespans due to faster aging and higher rates of cancer and orthopedic disease. Mastiffs typically live 6-10 years. Responsible breeding and maintaining a healthy weight help maximize lifespan.
How much does an English Mastiff eat per month?
An adult Mastiff (160-230 lbs) eats 6-10 cups of food per day. Quality large-breed kibble costs $120-$220 per month.
What are the biggest Mastiff health expenses?
Hip and elbow surgery ($5,000-$12,000 per joint), bloat/GDV ($3,000-$6,000 emergency), cancer, and cardiac disease. Medication and anesthesia costs scale with body weight, making all procedures expensive.
