刚刚google 出来的,You’ll find quite often in working with mellow dogs that they have the type of personality that can change. At certain times, they can get excited and at other times they can be laid back, but so much of this is dictated upon you or the situation at the time. 感觉和屁屁还挺象的,有的时候很兴奋,有的时候又是很懒的。
