I actually came on here to post the same question..lol Chloe is 8 months now and I have just started hearing it too. She is also fearless jumping from couch to couch even jumps from back of couch to ground sometimes which scares me so much. And her favorite spot to rest or chew her nylabone is literally on my shoulder while i'm sitting on the couch. (partner calls her my parrot) So I hear it often as shes right next to my ear. Any how its just like knuckle cracking and I found some stuff online I was thinking of trying just as a preventive measure, not sure if anyone here has used this product before?
