Seal assemblies for dock shelters and dock seals at a loading dock are disclosed herein. An example seal assembly includes a foam pad, a pliable cover to couple to the foam pad, and a shield to attach to the foam pad. The shield has a first end and a second end. The first end is to couple to at least one of the foam pad or the pliable cover and the second end is to project adjacent a vehicle-engaging surface of the foam pad. The shield is to move relative to the foam pad between a standby position when a vehicle is in a non-engaging relationship with the vehicle-engaging surface and a deflected position when the vehicle is in engagement with the vehicle-engaging surface.
