[Bear GSD]

For the past couple of days whenever Bear gets up from a down position I hear this clicking sound that sounds like it's coming from his elbows?
I only hear it when he gets up, it's kind of like the noise my knees will make sometimes.

I have palpitated his elbow area and it doesn't creak when I do that. He is not in any pain or limps at all. He is pretty much acting like himself other than being a little creaky. I haven't had his hips or elbows xrayed yet, I was waiting for him to turn 18 months before I decided I would have them checked.

I've looked and can't seem to find any information on this? Should I be worried? Does anyone have a creaky dog? I have started him on Cosaquin just to see if it was maybe tight joints, I know I need to take him in to see the vet on it, but just thought I'd ask here first.
