My puppy's jaw locked and mouth shook while yawning. Is it serious?

Updated on September 23rd, 2025

Pet's info: Dog | Mixed Breed Medium (23 - 60lb) | Male | neutered | 50 lbs

My puppy Brody is about to be 5 months this month and he was yawning and it's like his jaw locked mid yawn and his mouth was shaking and I massaged the muscles and it stopped and he went back to complete normal. He's eating and drinking normally and playing as his usual self? Is this something I should be worried about?

I wouldn't be concerned about this unless it is happening repeatedly. If it happens again then I would have your vet look at his jaw to see if it painful or malformed and potentially take X-rays. as of right now he sounds like he is doing well so just keep a close eye on him. I hope this helps!

This is a quite rare presentation. In terms of differentials this may be due to an inflammation of the temporomandibular joint, dental problems, or sometimes even early stage ear infections (in the inner or middle ear).
A clinical examination at your local veterinarian is essential to confirm these clinical suspicions and treat appropriately.

This can be a sign that Jr has a dental problem, and the shaking can be due to pain. Yes, I do think you should take him into the vet. The vet can diagnose what is causing the shaking, and can treat him for it. Best of luck, I hope this helps!

Is it normal for my puppy's jaw to shake when excited or playing?

This is likely just because she was really excited to be playing so I would not be too concerned. If she continues to shake her bottom jaw even when y’all are not playing then I would have your vet take a look at her. I hope this helps!

Why is my puppy's jaw trembling when sniffing? Is it a seizure?

Some dogs will have focal seizures known as 'chewing gum' seizures where the mouth will tremble or they will make chewing motions. Usually dogs will act a little disoriented after a seizure like this, but some dogs don't. If you think he may be having seizures you should see a veterinarian right away. It might be helpful to video an episode to show your vet. Of course it's possible that this is just a behavioral tic too, but it's better to be safe and have a veterinarian examine Mega to make sure.

Why does my dog's chin quiver when he yawns? Should I worry?

It is possible that this is not a problem for Tony, especially if he has done it for a long time. However, quivering of the jaw could indicate pain at the TMJ or dental disease. I would recommend that Tony be checked over by a vet to make sure there is no obvious problem that can be treated to resolve the quivering.

My 11-year-old dog's jaw is twitching. Should I be concerned?

Centralized muscle spasms, could indicate a neurological condition that can vary in severity, so it is hard to tell without examining him myself and running the necessary testing. However, if he seems stable otherwise I wouldn't worry too much. Especially if the spasm seems to only affect his jaw. The most important thing is to monitor him for overt signs of a serious problem and to have him evaluated by your local veterinarian soon for a full neurological work-up. This does not sound like it is cause for an ER vet visit; however you should aim to get him examined within the next 1-3 days if possible.

My dog's mouth tightens, baring teeth, and he whimpers. Is it serious?

This could be a form of seizure activity. I recommend getting your dog seen by your vet as soon as possible for an exam and lab work. If you can get a video of the episode, please do, so your vet will know what you're seeing. Sustained or repeated seizures can cause the body temperature to rise to dangerous levels and increases the risk of brain damage. When you have a chance, take a look around and see if you can find anything he might have gotten into, since poisoning is one of the causes of seizures. If he has a history of liver or kidney disease, this is also a potential cause. Sometimes we never know why a pet has a seizure. If he does have a series of seizures, your vet will want to do an exam and bloodwork to try and determine a cause and potentially put your pet on anti-seizure medication to lessen the chances of this happening again in the future.
