Popping sound when breathing

[Cobbles]

Hi I have a one year old Hermann. He is acting normal. Eyes are bright and eating well. He has started making this popping sound when breathing though. What should I do? Does he need to go to the vet? Or is there something I need to look at , at home. Thanks

What are your temps, day, night, basking?
I would raise day temps to 85 do not let night temps go below 75 and be sure there is a proper day basking temp of 95-100.
Keep the day and night temps I listed above for a couple weeks and see if the sound goes away.
If so, keep the temps there for about a week or two longer then you can put them back to normal. Basking temp should always be as I listed.
