一隻 沒有喝孟婆湯，始終認真生活，並讓狗生有價值的 狗

這隻狗確實有我們人類需要學習的地方，比如：付出、認真生活、思考生命的意義、活的有價值。

結尾那段：

So, in all my lives as a dog,here's what i've learned.Have fun,obviously.whenever possible, find someone to save, and save them.Lick the ones you love.Don't get all sad-faced about what happened and scrunchy-faced about what could.Just be here now.Be here now.That's a dog's purpose.所以當了幾輩子狗，我終於明白了，首先要開心，只要有可能，就竭盡全力去幫助別人，舔你愛的人，對過去的事不要一副苦瓜臉，對未來也不要愁眉苦臉，只要活在當下。活在當下，這就是狗的使命。

So,what's a man's purpose?那麼一個人的使命是什麼？

開頭：

What is the meaning of life?Are we here for a reason?Is there a point to any of this?First,I had no idea what was going on.I...I couldn't see a thing.It was warm.There was my mother.Everyday,I had fun.Was having fun the point?The whole point?No,it couldn't be that simple.

And then it was over.No more fun.It seemed like such a short life.I mean,what exactly did I do?There was some playing.There was some eating.I dug in the dirt.But when I really thought about it,it didn't add up too much.

活著的意義是什麼，我們為什麼活著，活著有什麼使命嗎？我每天都很開心，開心就是意義嗎，全部的意義？不，不可能這麼簡單。

然後沒就沒有然後了，開心不再，感覺這輩子太短了，我到底做了什麼，我玩過遊戲，吃過東西，還挖過泥巴，可是仔細想想，好像也沒有別的了。

上文也適用於人類思考自己。

像製作地溝油的那類人，活的還不如這條狗。

Have fun,obviously.whenever possible, find someone to save, and save them.這一句博愛(基督教思想，儒家思想)的話，包含了佛教慈悲和拯救世人的思想。

其實片中輪迴的思想也是印度古老宗教的思想。只是這隻狗狗沒有喝孟婆湯。

「誠外無物」，誠，就是誠懇，誠實，有信用，真實，不虛偽，誠就是真實的存在，狗是最「誠」的，而人呢？具備這些特質嗎？虛偽，虛假，欺騙，陰險，利用，自私……

單詞，狗dog，上帝god。
