A lot of dog actions bother my sensory sensitivities. The barking startles me and hurts my head, they tend to lick or slobber which bothers my skin, they often have an unappealing odor, and they invade person space often. So I like to see dogs just not be super close to them. There are some exceptions. I know a few dogs who are very well behaved, and I feel comfortable around them.
I think you've nailed it. Especially for small children with sensory sensitivities, a dog can be a far-too-large hairy undirected cannonball with blunt claws, making loud, sharp, unexpected noises, dripping organic fluids, smelling bad, and absolutely determined to get you (including, in larger untrained dogs, knocking you down and stepping all over you). Even as an adult, a large dog moving at speed can skittle you or cause minor abrasions purely through unbridled enthusiasm, or bark like they're trying to bring the building down.
It can help to read up on dog psychology and body language, to firmly take charge of interactions with dogs, and to initially interact with dogs which are slow-moving and rarely make noise (older, well-socialized dogs, generally). When dogs are something of an open book, they can be less intimidating and unpredictable.
