Raw Dog Food for Large Breeds: Feeding Great Danes, Rottweilers & Mastiffs

Feeding Raw Dog Food to a large or giant breed dog comes with a unique set of nutritional challenges that every big-dog owner needs to understand. Whether you share your sofa with a Great Dane, a Rottweiler, a Mastiff, or a Saint Bernard, their dietary requirements during both adulthood and the critical puppy growth phase differ significantly from smaller breeds. Getting it right supports strong joints, healthy weight, and steady development. Getting it wrong, particularly during the first eighteen months of rapid skeletal growth, can contribute to serious orthopaedic conditions that affect your dog for life.

In this essential episode of The Dog Food Expert Podcast, Alex and Daniel tackle the specific considerations of feeding Raw Dog Food to large and giant breeds. We start with practical advice on portion calculation and bulk-buying strategies that make feeding a 50-kilogram dog genuinely affordable.

We then address the topic that worries every deep-chested breed owner: bloat. Drawing on research published in peer-reviewed veterinary journals, we explore the identified dietary risk factors associated with gastric dilatation-volvulus (GDV) and discuss how the non-expanding nature of fresh food compares to the swelling behaviour of extruded dry kibble inside the stomach.

Finally, we dedicate significant time to the most critical subject of all: feeding large breed puppies. We explain why controlled, steady growth is far more important than rapid size gain, and why large breed puppies are uniquely sensitive to excess dietary calcium during their skeletal development.

In this episode, we cover:

• Portion Sizes for Big Dogs: How to apply the 2-3% bodyweight rule to large breeds, and why giant breeds often sit at the lower end due to their slower relative metabolism.
• Bulk Buying on a Budget: Practical strategies for making large breed raw feeding affordable using 10-20kg bulk boxes and calculating true daily cost.
• Bloat and Diet: What peer-reviewed veterinary research tells us about the dietary risk factors for GDV, and how fresh food behaves differently in the stomach compared to extruded kibble.
• The Growth Rate Trap: Why overfeeding a large breed puppy to maximise size can lead to serious joint and skeletal conditions including hip dysplasia.
• Calcium Sensitivity: Why large breed puppies cannot regulate calcium absorption as effectively as smaller breeds, and how to manage bone content and supplementation carefully during the growth phase.

Why Listen? If you own a large or giant breed dog and want to feed them the best possible diet without making costly mistakes, this episode gives you the breed-specific knowledge you need to feed raw safely and confidently at every life stage.
