Irish Wolfhound
The Irish Wolfhound is well-known for its height, and many saw them as a perfect guardian dog. They could protect people from wolves and even hunt them. They are taller than Great Danes, and even if they’re the tallest among the dog breeds, they aren’t the heaviest.
They can come in colors like black, grey, white, red, brindle, wheaten, and fawn. Even if they are big dogs, they won’t wreak havoc in your house unless you leave them alone for a long time. Irish Wolfhounds, like most large dogs, have a short life span averaging at seven years. Their leading cause of death is bone cancer and dilated cardiomyopathy.
