My dog-breed prejudice is that dogs bred to be human helpers (hounds, collies, huskies, spaniels, etc) are trustworthy, and dogs that have been bred to be fighters because that is what we needed at the time will fight given the chance. The useless little toy dogs should be ground up and fed to the fighters, and then the fighters killed off for eating them.
For most of my childhood, we had a dog we got for free from the local Game Warden, halfbreed of his bloodhound and water spaniel. The dog's name was Gypsy, but was baby-talk-named Bitsy by my little sister and that name stuck. That dog was a cross between being the seventh child in the family and the third parent. She eventually succumbed to old age - which is another benefit of a family dog - their life cycle speed is 7x of humans so you get to experience its entire life.
