米卡吃了大约2个月，跟以前一模一样，性格没有任何变化。我个人觉得是你家的工人的心理作用，她觉得小沙吃了生肉会变性格，就把小沙正常的小狗的举动，比如闻和拽跟生食联系起来了。
其实我倒是感觉，吃了生食之后，米卡高兴了不少，精神头好很多。也许你家小沙也是觉得自己精神了，同时觉得周围的气味更清晰了，才会兴高采烈地到处闻。不过这是我的估计，没啥科学依据的。
我们去买生食的那家有5条大狗，吃了一辈子的生食，温顺得跟绵羊一样。另外，每次去买都好多人，从没有人说狗吃了变暴躁的，他们吃得时间比我们长，如果发生这样的情况肯定就不来了，是吧？
医生是这么说的：
Feeding a dog a properly balanced diet can only affect his brain and brain chemistry in a positive way. A dog can develop digestive problems because of too much grain and a lack of proper hydration in his diet. Digestive problems affect brain chemistry, which is the main factor in behavior besides training and other external circumstances.
A dog won't realize that the meat is raw instead of cooked and all of a sudden become a wild dog. He will be better able to tolerate stress and will be more responsive to training. Therefore, he'll be much less prone to aggression.
吃生食是一种选择，不是必须的。我认为选择最适合自己的情况的方法喂养就可以了，有狗狗吃了一辈子的袋装食物，不也是开开心心的？
