Dogs + babies

Hey everyone! Before I start this small rant I just want to throw out there that I love dogs, and that I love being greeting spontaneously by dogs and I in no way don't love other people's dogs okay? But when you have a baby or a little kid and someone comes up to you or let's their dog loose and it comes running up to your kid it's extremely nerve racking, yes I KNOW your dog is probably the most kind thing in the world but my kid doesn't, and I've never met this dog before and I don't know what it's like, so yes I would love to meet your dog but don't let it just run up to my kid. While I know a lot of dogs are 100% harmless I don't know if yours will be, please people when having dogs in public that aren't trained to stay by you only put them on a leash, it's scary for those who don't like pets and young children.
