To put something on ice means to delay something until some point in the future. To postpone something. Usuall, this refers to something you have to do. Often, this is something that that you are currently doing or something you had planned to do now but, for some reason, you aren't able to finish it now or it would make more sense to do it later. A husband might say to his wife something like, "Sorry, Honey. Something came up at work, so we'll have to put our plans for the weekend on ice." In this case, the husband and wife had planned to do something, but will have to postpone it till some other time. In the following example, a group of employees has been meeting for some time, but is getting nowhere. They decide to stop for now and resume at a later date when the people might have some fresh ideas.

Mr. Drake: So, does anyone have any other ideas? We've been talking about this for four hours now.
Robert: Sorry, sir. My brain isn't functioning any more.
Mr. Drake: Alright, people. Let's put this on ice for now and meet again next week. In the meantime, be sure to think of some new ideas. 

This phrase come from the fact that, if you weren't going to eat something right away, you could put it on a block of ice (in the icebox or ice house–Nowadays you would use the refridgerator or freezer) and save it for later.  

いただきます。

Itadakimasu basically mean, "I will receive it." It is a very polite expression used when someone offers you something or gives you something. You would say it to someone high above you in social status. It is the keigo (honorific) form of "moraimasu." It is also what one says before starting to eat. In this case, it means, "I am about to receive this meal."

This expression originally comes from the word "itadaki," which means the top of a mountain. It can also mean, "to be crowned with." In the olden days, if someone received something from a superior, he would bow his head and place his hands, palms-up, over his head in order to receive it.

 お蔭様で （おかげさまで）

Okagesama de is a often-used phrase in Japan. You can kind of think of it as, "thankfully" or "thanks to God (or whatever powers that be)." It is often used as a reply to, "How are you." You can reply, "Okagesama de (genki desu)." Even without the "genki desu," it is understood that it is implied. In this case, it would mean something like, "Thankfully/Thanks to God, I am fine." It can pretty much be used any time someone asks you how something is and you want to reply that everything is well without appearing to be boasting about it. If someone asks you how you did on a test, you could say, "okagesama de." In this case it is like you are saying it went well without seeming to boast that it is a great thing or that you had anything to do with it.

 今回は少し楽しくない表現をみてみましょう。「go to the dogs」です。
これは、「だめになる、 落ちぶれる、荒廃する、堕落する」という意味です。

長年、続いてきたもの、或いは、過去に良い評価を得ていたものが、徐々に質を落としていくといった場面で使われます。

例えば、会社（This company is just going to the dogs.）、教育システム（The educational system in this country is going to the dogs. ）人生（ My life is going to the dogs.）、結婚（My marriage is going to the dogs.）、（老朽化した）家屋（This house is so run-down. It's just going to the dogs.）などです。 下の例で、トムは、１０年以上勤めてきた会社を辞めるつもりです。サムは驚いて、「なぜ？」と尋ねます。トムによれば、最近、この会社で起こったことを振り返る時、どうもこの会社は駄目になっていくように思えてならないということでした。

Tom: Hi, Sam. I just wanted to say it's been good working with you.
Sam: What do you mean by that?
Tom: I just gave my notice. I'm leaving the company.
Sam: What? Why? You've been here over ten years.
Tom: It's something I've been thinking about for a while. With everything that's been happening lately,I can't help feeling that it's just going to the dogs.
Sam: Well, it's been good working with you, too. I hope things work out for you.

食べ物の質が悪くて、人が口にするのは適当でないから犬に与える。
このイディオムのイメージはこんな感じです。
しかし、今日の愛犬家にとっては、「とんでもない！」といった気持ちにさせられますね。
