The dog's mouth has serrated meat valgus, which is generally caused by skin inflammation caused by long-term drooling or food residue.

If this happens to dogs, it is recommended to take them to the pet hospital for examination in time to find out the specific reasons and provide targeted treatment.

At the same time, we should also pay attention to keep the dog's mouth clean and dry to avoid the dog being in a humid environment for a long time and reduce the occurrence of skin inflammation.
