Reuger makes noises like that all the time. I think that they call it reverse sneezing on YT. When he does it I just put my hand over his nose. I don't know if it distracts him from the sneezing or if it calms him down but it works. He does it enough that he'll come to me when he's doing it so I can help him out. He almost always does it after having a bath and running all over the house. It sounds a lot worse than it actually is. BTW-I agree you should get your dog a harness instead of a collar.
