I must be a total idiot!!!
Doc, I'm sorry but your Father was making a very foolish statement and you are very foolish to repeat it!!
The Irish Wolfhound of which I have 3 are the tallest dogs in the world, two of them have been attacked by other dogs in the past each time another of my dogs will run to their aid, they will do everything possible to avoid fighting, the other dog would just grip the attacking dog and hold it without hurting it. My dogs have never fought and never would unless defending me or Mrs RATTER or unless under extreme provocation.
They are considered to be one of the most gentle breeds alive their closest dog to size are the Great Dane, again a very gentle placid dog.
Saying all that, I really would not like to be on the receiving end of an attack by one of these giant breeds, I have seen them crunch through bone 2 inches thick like pencils, and weighing in at over 10.5 stone they have the weight and strength to do some serious damage.
I have never even heard of an attack by a giant breed such as these beautiful gentle creatures.
