2. Dogs grind their teeth due to parasites in their bodies.
3. Indigestion caused by improper dog diet can also cause dogs to grind their teeth.
4. When some dogs are angry, they may also grind their teeth and growl at the same time.
Solutions to dogs grinding their teeth:
1. If teeth grinding is caused by tooth replacement, owners can buy teething toys for their dogs, such as teething sticks.
2. If the teeth grinding is caused by internal parasites, the owner needs to take the dog to the animal hospital for internal deworming.
