Help with puppy! Honking noises wet nose

I have a 6 week old puppy he makes a honking noise every now and then and is also breathing from his nose quite loud every now and then. The person who gave us the puppy (which I know was WAY too early we asked for her to keep them longer but she didn’t) she told us that he has been reverse sneezing like his dad does but what worries me is the sounds during his sleep and the slightly wet nose every now and then. Any suggestions/thoughts on what it is? I don’t think it’s anything contagious as I also have his brother and he is fine. I’m a first time dog mama and it’s driving me crazy I’m so worried!
