It is hard for me to describe this, but my 4 y/o Rusty seems to "click" his lower jaw much more frequently recently. It used to be when he just woke up, his jaw would "seize" for a few seconds, now it is happening more frequently. We tried to explain this to the vet who said that it wasn't a problem but maybe we didn't explain it properly. It is almost like when someone is double jointed and they can "click" and the lower jaw just shakes. It is so frustrating that I can't explain it. If no one has ever seen this before, perhaps I will take a video and bring it to the vet.

Does this sound familiar to anyone? Thanks in advance.
