Four-month-old puppies generally do not suffer from progressive jaw trembling. The shaking is more likely a transient issue that occurs as the puppy’s nervous system matures.

Rarely, a quivering jaw may be a sign of poisoning or a serious neurological disorder. However, I’ll bet that your son’s puppy is simply going through a phase. I don’t think you should worry too much about this matter.

Why does my dog open and close his mouth repeatedly?

Dogs may open and close their mouth repeatedly if they are choking. The dog is having difficulty getting enough air so the repeated open and closing of the mouth may indicate a dog’s attempt at trying to dislodge whatever foreign object is stuck in the dog’s throat.

While there are a lot of causes of lockjaw in pets, thankfully they are all relatively rare. Still, if you notice your pet having trouble picking up food or chewing, or if you see wasting away of the muscles on top of your pet’s head, trismus may be the reason, and it’s worth a trip to the vet.

What does it mean when a dog’s teeth chatter?

Intense emotions, such as excitement, fear, or anger, are known to trigger teeth chattering. That said, if your dog is so aggressive that his teeth are chattering, the aggression may be a medical symptom. It’s best to consult a vet in this case.
