A trembling dog's mouth may be caused by nervousness, fear, cold weather, physical pain, etc. It is recommended that the owner pay attention to observation. If the dog just trembles at the mouth and does not have any other abnormalities, then it may be caused by nervousness, fear or cold weather. The owner does not need to worry too much. He only needs to calm the dog's nervousness or do a good job. Just keep warm. However, if the dog is also accompanied by symptoms such as listlessness, loss of appetite, lethargy, fatigue, etc., it may be caused by physical pain. At this time, timely medical treatment is needed to avoid delaying the condition.
1. Nervous and scared
When a dog feels nervous or scared, his mouth will tremble unconsciously. This situation often occurs in dogs that have just arrived in a new home, or dogs that are frightened by certain noises or other things. At this time, what the owner has to do is to take measures to reduce the dog's fear, such as comforting it by stroking, picking up, etc. The dog's nervous and fearful mood will be relieved after the dog's nervous and fearful mood calms down.
2. Cold weather
When the weather is cold, the dog’s mouth will tremble uncontrollably. Therefore, owners must pay attention to keeping their dogs warm in the cold winter, such as putting clothes on their dogs, thickening their mattresses, etc., to prevent their dogs from catching colds.
3. Body pain
When a dog is in pain, his mouth may tremble. At this time, the owner should pay attention to observation. If the dog is found to have symptoms such as listlessness, loss of appetite, lethargy, fatigue, etc. in addition to mouth trembling, it is likely to be caused by physical pain, and it is necessary to go to the pet hospital for examination and treatment as soon as possible.
