10-20 spots in 30 minutes would have me rush him to the vet, could be everything, dogs don't show paint like we do, they can be calmed, but in pain.
Maybe a spider bit him they do looks like eruptions caused by a spider bite, so i'd take him to the vet, either now, or tomorrow first time, but lets just hope that the 40 spot per hour ratio doesn't continue.
