Guide to Selecting the Best Dog Food for Mastiffs

Best Dog Food For Mastiff

This segment provides insights into choosing the optimal dog food for your Mastiff. Before delving into specific dietary considerations, it’s beneficial to understand the breed’s overall nutritional requirements. The recommended food for Mastiffs encompasses the following aspects:

Nutritional Needs of Mastiffs:

Tailoring the diet to your dog’s life stage is crucial. Puppies, for instance, require distinct nutrient levels compared to older dogs, and their feeding frequency is higher. Essential elements for every Mastiff include proteins, lipids, calories, and minerals.


Opt for a high-quality diet rich in animal protein. While vegetables and whole grains can contribute, they should not dominate the main components. Protein plays a vital role in muscle mass development, ensuring your dog remains agile and robust. Look for ingredients such as fresh and meat meals, with meat meals having a higher protein content than fresh meat.


Animal fat is a common ingredient that provides energy and enhances kibble flavor. Fatty acids, including DHA (an omega-3 fatty acid), are particularly beneficial for maintaining healthy skin, hair, and the cognitive development of puppies. Sources like canola oil, coconut oil, and fish oil can contribute additional fats. Be cautious not to overfeed fat, as it may lead to weight gain.


Your dog’s calorie requirements depend on factors such as exercise and metabolism. A 100-pound dog may need around 2,000 calories or 20 calories per pound of body weight for an average adult. Understand the calorie content per cup of food to ensure proper feeding. Consult your veterinarian for guidance, especially if your dog has medical conditions affecting caloric needs.


Incorporate Taurine to support heart health. Calcium and phosphorus are essential for robust bones, while including glucosamine and chondroitin is crucial for joint maintenance. A well-balanced diet should offer the appropriate ratio of vitamins and minerals, promoting a healthy immune and digestive system.


The cost of nourishing a sizable dog like a Mastiff, potentially consuming 10 to 11 cups of food daily, can be significant. Striking a balance between providing nutritious meals that meet dietary needs and adhering to your budget is essential. While it’s not an insurmountable challenge, it’s crucial to be aware that feeding a giant dog comes with higher costs compared to smaller breeds. Consider the long-term financial commitment associated with maintaining the optimal nutrition for your Mastiff.

Special Considerations:

Individual health conditions and dietary sensitivities may influence your choice of dog food. Some Mastiffs may require specialized formulations due to allergies or medical issues. Consulting with your veterinarian can help identify any specific dietary considerations based on your Mastiff’s unique health profile. This personalized approach ensures that your dog’s nutritional needs are met effectively.

Best Dog Food For Mastiffs

Nutritional Requirements for Mastiffs

Mastiffs, with a weight range of 160 to 230 pounds, are not particularly active due to their massive size, preferring to conserve energy for necessary activities.

Despite their lower activity levels, Mastiffs have a substantial appetite, and potential owners should be prepared for the significant food consumption associated with this breed. To maintain a healthy weight, adult Mastiffs require approximately 3500 calories daily. This high-calorie intake translates into a substantial amount of dog food. The caloric needs of Mastiffs vary with age, with growing pups needing more calories than adults, and senior dogs benefiting from higher quality proteins and lower fat content.

The optimal approach is to provide specially formulated large breed dog food, considering the unique nutritional needs of Mastiffs. Large dogs like Mastiffs require additional joint support and a diet that minimizes the risk of bloating compared to smaller breeds. Additionally, the dog’s life stage should be taken into account when selecting appropriate food.

Feeding Guidelines

Mastiffs are highly susceptible to bloating, a condition that poses a risk to their stomachs and may necessitate immediate surgery in severe cases.

To mitigate the risk of bloating, it’s advisable to divide their meals into three or four smaller portions throughout the day. Retrieving uneaten food after 30 minutes prevents grazing, a habit that puts Mastiffs at risk of obesity and complicates monitoring their food intake.

Calorie awareness is crucial in determining the appropriate amount of food for Mastiffs. Not all dog foods are equal, and low-quality options may meet caloric needs but lack essential nutrients, increasing the likelihood of obesity.

It’s essential to resist overfeeding, particularly during a Mastiff’s growth stages, as rapid growth can strain bones and joints. Overeating in younger dogs may lead to long-term bone and joint issues in their later years.

To calculate the right amount of food for each life stage, use a dog food calculator and choose a high-quality, sizeable breed-specific food for your Mastiff.

Choosing The Best Food For Your English Mastiffs

The English Mastiff, a formidable and sizable breed weighing up to 220 pounds, is renowned for its imposing appearance and gentle nature. Originally bred for guarding and fighting, this breed has evolved into a companion known for its kind temperament.

The term “Mastiff” traces its origin to the Latin word “mansuetude,” meaning “tame,” reflecting the breed’s history of being trained for battles and arenas against lions. The English Mastiff exudes boldness, self-assurance, and dignified bearing. Despite their intimidating size, English Mastiffs are generally reserved, enjoying moments of solitude while thriving in the company of their closest human bonds. Their affection extends to children, although their bulk may occasionally lead to comical falls.

To maintain optimal physical and emotional well-being, daily exercise is crucial for English Mastiffs, as they have a tendency to gain weight due to their love of eating. Free-feeding is not advisable for this breed. While generally healthy, English Mastiffs are susceptible to bloat, a condition that can be triggered by eating too quickly and excessively. Choosing a diet with large kibble pieces designed for large and giant breeds can help prevent overeating.

Drooling and flatulence are common traits of the English Mastiff. A healthy, easily digestible diet can contribute to reducing excessive gas. When selecting dog food for English Mastiffs, aim for a minimum of 18% protein and 5% fat in order to meet their nutritional needs. Paying attention to the unique characteristics and requirements of this breed will ensure that your English Mastiff enjoys a healthy and balanced diet.
