Sometimes in the mornings, or after Murphy's been snoozing for a while, his front leg will make a 'cracking' sound when he gets up. He never shows any signs of being lame or stiff, but I was wondering if I could give him a supplement or something to help him.

He's only 2, it doesn't do it all the time but I'm not sure if it's a normal thing or not. I mentioned it to the vet but he didn't seem worried about it
