Considering the reputation that they have, you would automatically assume that a wolf would make a wonderful guard dog and that nobody would venture anywhere near your home or whatever it was they were protecting. However, if that is indeed what you thought, then you would be very, very wrong.
Instead, a wolf would actually make a horrible guard dog, and it is all due to something that people either do not know or seem to gloss over for any number of reasons. You see, a wolf is known to actually be terrified of things that are unknown to them. In other words, if they were guarding an area and heard something that they did not understand, then they would have a tendency to run in the complete opposite direction. This is hardly what you want your guard dog to do.
A wolf is tough to see simply because it will not even bark at an intruder since it is too busy running away, so they are perhaps not as fierce as they are reported to be in the media. Oh, and if you thought that you could sneak up on them, then you would be incorrect because they can hear noises up to six miles away and have developed over 200 million scent cells, whereas us humans have a mere five million.
