No, some have had bad experiences with them at some point in their lives. There have been way too many people bitten by dogs, some so bad that surgery has been required to save their lives, other have been disfigured. Many people have been attacked or chased by them. I personally have been bitten by a dog, but I still like them.
There other day I was at a pet shop, and a woman and her daughter were looking at a St. Bernard puppy in one of their cubes, at first the puppy was very docile, then it got a little aggressive and the two were very frightened. I got one of the clerks to assist them, it was not a good experience for them.
Have a wonderful day.
