About Bullmastiffs
The Bullmastiff was developed in England during the 19th century by crossing English Bulldogs with Old English Mastiffs. Originally bred by gamekeepers to apprehend poachers on large estates, these dogs were trained to track quietly, tackle intruders, and hold them without mauling.
Bullmastiffs are large, powerful dogs with short coats in fawn, red, or brindle colours, often with black masks. They're known for their calm confidence, natural guarding instincts, and strong loyalty to their families.
These dogs are gentle with their families but naturally protective of their territory. They require moderate exercise and are generally content with daily walks. Early socialisation and consistent training are essential due to their size and strength. While generally healthy, potential concerns include hip dysplasia, elbow dysplasia, and bloat. Their short coat requires minimal grooming but they can be sensitive to extreme temperatures.
Complete Care Guide for Bullmastiffs
Expert advice on keeping your Bullmastiff healthy, happy, and thriving at every stage of life.
Proper nutrition forms the foundation of a Bullmastiff's health and longevity. These powerful, muscular dogs require carefully balanced meals rich in high-quality protein to maintain their impressive physique and support overall wellness. A well-planned feeding schedule should account for your Bullmastiff's specific life stage, as nutritional needs shift significantly from puppyhood through senior years.
Portion control plays a crucial role in maintaining a healthy weight, as Bullmastiffs can be prone to obesity. Work closely with your veterinarian to establish appropriate serving sizes based on your dog's age, activity level, and current weight. Breaking daily food allowances into multiple smaller meals helps prevent bloat while supporting steady energy levels throughout the day.
Fresh, clean water should always be readily available, with bowls refreshed multiple times daily. Including appropriate amounts of fibre through vegetables and select whole grains supports digestive health, though any dietary changes should be introduced gradually. Monitor your Bullmastiff's weight regularly and adjust portions accordingly, as excess weight can strain joints and contribute to health complications in this large breed.
