Irish Mastiff

The Irish Mastiff is not a purebred breed, but a hybrid that is the result of mixing a Mastiff with an Irish Wolfhound. Since the breed is hybrid, sometimes the name may be misleading, because it is not a guarantee that all of the dogs will be 50% of each parent breed due to the popularity of multi-generation breeding. Not much is known about the breed but there is some speculation that the breed has existed before in Ireland, but went extinct due to the frown upon mix breeding. To best know the Irish Mastiff it is most helpful to research the parent breeds.
