I am sorry to hear about this. In my experience, Thor is unpredictable about which dogs he is good or not with. He is good with most bigger dogs, but does bark agressively at them at first. It's wierd. I think it is all about socialiazing them when they are young and since your dog is still young you have time to do this. Don't worry, just keep hard at his socializing!!!
Good luck!
