1、恐惧感

当一只未适应新环境的狗狗在晚上不停地叫嚷，这通常是因为它对陌生的空间感到不安和害怕。为了缓解这种情况，主人应该花费更多时间与狗狗相处，让它逐渐熟悉新的居住环境。通过提供食物和玩具，以及参与互动游戏，可以加深彼此的情感联系。一旦狗狗适应了新环境，它的叫声就会减少。

2、生理需求

有时，dog's incessant barking at night may be a result of unmet physical needs. For instance, if the dog is hungry or thirsty, it will vocalize its discomfort. To address this issue, owners should ensure that their dogs' basic needs are met before bedtime. This includes providing adequate food and water for the night ahead.

3、高能量水平

如果一个没有得到充分锻炼的dog在白天保持低活动水平，那么到了晚上，它可能会因精力过剩而变得活跃并且吵闹。解决这个问题的一个方法是增加白天的运动和娱乐活动，以消耗其多余的能量。当夜幕降临时，一个疲劳的小动物就不会再发出那么大的声音。

4、警觉性高

某些dog breeds are naturally more alert than others, which can lead to excessive barking at night due to their heightened sense of awareness. If your dog starts barking in response to external noises or movements, you can train it to become less reactive over time.

5、健康问题

Dog's persistent whining during the night could also be an indication of underlying health issues such as pain or discomfort. It is crucial for owners to monitor their pets closely and seek veterinary care if they notice any unusual behavior or symptoms beyond just constant barking.
