So I searched on the threads for "tmj" and "jaw" with no results.
Cooper woke up at 4 am with his jaw locked open, chattering to try to close it. It made him whimper a bit.
No recent trauma or injuries that we can think of.
We took him into the vet this morning. She said she could feel a grinding noise, and prescribed Cosequin for joint health. She said he could continue eating solid food and that we could massage the muscles to get it back into place when he has an incident.
The locking has continued through the day. I know how to deal with jaw pain in myself (I have arthritis in my tmjs and am missing enough bone in one to cause major problems), but you can just tell a dog to not hyperextend his jaw when he yawns!
Any experience with this?
P.S. It's 50 degrees warmer in Minnesota than it's been in a week!!!! Some little basenji has been very upset at the weather!!!
