Breed Details


The Irish Mastiff is a cross between an Irish Wolfhound and a Mastiff purebreds. They are called hybrids or designer dogs due to their origination from two different pure breeds.

The Irish Mastiff is a large breed dog that can stand up to 38 inches and weigh in between 120-250 pounds. These are large size dogs with a gentle and loving attitude.


The Irish Mastiff is found in different colours of their parent breeds. Common colours for these dogs are black, black and tan, gray, red, silver and white and any mix of these colours.


Their coat can be medium length rough and wiry like an Irish Wolfhound or short and fine like a Mastiff.


The Irish Mastiff dogs are gentle, loving and loyal dogs. They are easy-going and even-tempered dogs that are very good with children. They also get along well with other dogs and pets in the family. These dogs bond themselves strongly with their family and are very protective of them. The Irish Mastiff dogs need to be trained NOT TO JUMP OR LEAN due to their large size and heavy weight. They are stand-offish with strangers but mix with them after proper socialization. They are not very good watch dogs but can be used as deterrent due to their size. These dogs need lots of room to run but do not need any extra exercise than most other dogs. They can fit into an apartment life if ample exercise is provided but they ideally would need a large yard to play and run.


The Irish Mastiff dogs grow very fast and should not be exercised hard as they may develop joint problems.


They are easy to train and their eager to please attitude will make them suitable for gentle but firm training.


Though very large dogs, they do not need any more exercise than any other dog. A daily long walk or jog will keep them fit and healthy.
