Did You Know?
The size of the Mastiff may be intimidating, but he is a gentle dog who loves kids and even cats.
This breed comes from ancient origins and holds the title of oldest English breed. His strength and courage impressed those across Europe. The Romans took him back to Rome to fight with gladiators, bears and other opponents in the arena, while others in Europe used him for fighting, guarding and companionship.
While the breed has a history of fighting in arenas and pits, he is a great family companion and is relatively calm and docile. His large appearance makes him one of the largest breeds of dogs, and his wrinkles and jowls give him both a foreboding and comical appearance.
This breed makes a great family pet and protector. He loves children, and will go the extra length to protect them. He rarely barks but will bark if he feels threatened, or if he needs to alert his family of a possible threat. Steady, patient and docile, they do well in any situation.
They live on average 9 to 11 years, typical for a giant breed dog. Their large size has also led to several health issues including hip and elbow dysplasia, cystinuria, ectropion, persistent pupillary membranes, osteosarcoma, progressive retinal atrophy, seizures and bloat or Gastric Dilation and Volvulus.
While the short coat of this giant dog only needs occasional brushing, the folds and wrinkles over his head and neck can be problematic. They must be regularly cleaned and kept dry and free of debris or else they can become easily infected. They may also be prone to minor skin issues.
His easygoing nature makes this dog an eager and compliant learning. He should be socialized however, due to his large size and potentially suspicious nature. While he is eager to please, he may be slow to respond solely to his large size.
As a giant breed, care should be taken to keep him calm and not overexert his joints while growing. Long walks and play sessions are best, and they don’t require a great deal of exercise despite his giant size. He is happy both at home with family, or out on adventure with them.
