What happens when a dog grinds its teeth in its sleep

There are several possible reasons for dogs grinding their teeth in their sleep: 1. Puppies are in the teething period. 2. Short-term indigestion and food accumulation. 3. Parasitic infections that attack the brain. If the puppy is grinding its teeth, we need to prepare a teething stick for the puppy in advance; if the worm is present in the body, we can clean the dog’s litter and pay attention to giving the dog medication and avoid giving the dog raw food in the diet; if the digestion is poor, we can just give the dog dog food.
