在探索荷兰猪的日常饲养习惯时，我们发现它们通过各种肢体语言和叫声来与同伴沟通，表达自己的感情和需求。这些行为不仅反映了它们的情绪状态，还能够揭示它们对环境的反应、食欲变化以及社交互动。

首先，当荷兰猪处于陌生环境中，它们会表现出警戒性，头部抬高，全身紧绷，不断抽动鼻子。这说明它们对周围环境有所顾虑，并试图适应新的环境条件。

其次，如果它想要食物，荷兰猪会发出大声叫唤，同时将头部高举并且用前脚踏在食盆或草架上。这是明确表示自己需要食物的方式，让主人知道它的需求。

舔手指是一个新手经常遇到的情况。当新人把猪带回家后，推荐亲手喂食以增进感情，这时候就会出现舔人的情况。一般来说，刚领回家的猪对事物都不熟悉，所以伸出手指让它舔，可以分辨物体。如果你的手刚摸过菜叶胡萝卜等，它们也会舔你，因为你的手上有着食物味道残留。这种行为可能是因为怕被咬的小心或者喜欢（爱意）的表现，有时候抱起来还会舔，你这可能是想BB\NN了哦，要快点放回笼子里。

打哈欠也是一个重要信号除了下面提到的与等级有关以外，还表示它感到舒服了一般而言，与主人熟悉的猪会在主人身上打哈欠，这表示它们对你很放心哦~~另外感觉困的时候也会打哈欠，就像人一样。

清洁也是荷兰猪的一种自然行为，它们就像猫咪一样，用舌头不断地清理身体，比如洗脸、吃便便都是营养重吸收，不必刻意改正这个习惯。只吃半截或者只是叼一会就放下，也许是你给的营养含量太高了，便便里还有很多没吸收完的，所以他们就会吃，但由于本身已经摄入足够营养了所以只吃一半。有的DD都会发现 pigs常常这样“吃BB”，仔细观察就会发现其实他们是在“自我安慰”，由于DD发情比较频繁（基本上每天都会）所以他们也是要自我安慰一下子的。

挠痒痒是一种很普遍的情况，比如我家piggy 洗澡后背部还没完全吹干时毛发还是一条一条结在一起的时候，它们就开始挠背使自己的毛变得松一些。而小奶piggy也有这个动作。但不是因为病，而是为了保护自己比如水果的时候为了保护食物，他们就会蓬起来让自己看起来大一些但如果看到piggy毛突然膨开还是得引起重视极度虚弱的是“炸毛”的

蹦蹦跳跳通常表明hog is happy and excited, especially when they see their owner or get treats. They may also exhibit this behavior when they are playing or exploring their environment.

委屈和害怕则是不好的迹象。当hog feels threatened or scared, it will lower its head, flatten itself against the ground, and close its eyes. This is a clear sign of submission or fear.

寻求安全感也是正常现象，有时候new piglets might freeze up for hours on end as they adjust to their new surroundings. But if your hog has been in the house for a while and suddenly starts freezing up again, it could be a sign of illness.

攻击性则是一个需要注意的问题。当hog feels threatened or territorial, it will stand tall with its ears back and tail raised. If it attacks you directly, it may bite down hard on your hand.

兴奋和玩耍则另一个方面，当hog gets excited about something (like food), it will start making noises like "oink oink" and jump around in circles. When they play with each other, they often roll over onto their backs exposing their bellies to each other - a sign of trust.

摸头顶虽然有些hogs don't like having their heads touched but some do enjoy being scratched behind the ears where there are many nerve endings that stimulate pleasure hormones in the brain!

最后，我们必须了解到当hogs reach puberty around 6-8 months old (depending on breed) changes occur that can make them more difficult to handle: increased aggression from males towards females; females becoming more skittish due to hormonal fluctuations; both sexes exhibiting heightened sensitivity to touch and noise; increased energy levels leading to destructive behavior if not provided enough exercise! So remember patience is key!
