I do not have a dog, nor do I want one
But its more of a cultural thing. Most kids have a friend who has a dog and they want one too, however most frum families this is not the case as most dont have dogs and people dont grow up with one, so nobody has a dog
Most dogs arent vicious. People are thinking Rotwilers, Pitbulls, Doberman Pinchers or German Shepards and they might be scary, but do you really think a chihuhua is that dangerous or scary?
